Trying for a Baby Part 8

I haven't even visited my dad's grave yet, and now that I'm in the UK I probably won't get the chance. My parents were "older" when they had me, mom was 34 almost 35 and dad was 37. I wasn't exactly a surprise, but I wasn't exactly planned either. They had been trying for 10 years. Due to that I was and am an only child. I just hope that my husband and I have an easier time of it than my parents did. My husbands parents on the other hand had him when they were young, and we haven't told them that we are even trying yet. His mom would probably drain a whole bottle of wine if we did! She doesn't want to be a grandmother until she's older, but quite frankly, it's our decision. Don't get me wrong, I love his parents completely and they have both been wonderful since I moved countries.

On a completely different note, what are the chances of passing on food and medicine allergies to a little one? I'm allergic to all sorts of antibiotics, as well as barley, almonds, walnuts, and macadamea nuts. The nuts don't cause anaphalactic shock (thank goodness) but do cause a few days of a very uncomfortable mouth.

My BFs mum was older too, only started at 36 and went on to have three. See never know. I'm an only child too and my parents are abroad, not easy. I'm sure your MIL will love being a grandma despite being "too young" . I hope it happens soon for you

Anyway. About allergies, best speak to your doctor as I have heard varyious stories. Friends of mine have passed them on to their kids whereas others haven't at all. So not sure what it depends on

I could go through and find out which genes the allergies are on (if it's genetic) and play around with the stats on them. That's how I made it through my three genetics classes. Not sure I'd want to do that with myself though! I already know that there is a 50/50 chance of either boys or girls that we have being RG colour blind. Husband is and my dad was. I'm a genetics nut and sometimes delve too deeply into it!

I'm not too worried about it honestly. I suppose that the good news is that I know the allergy symptoms to look out for if it does happen!

Forgot to say, my mom is abroad as well. She's still in the US, but I'm here in the UK with the husband. It's lonely sometimes (mom and I are close, but have never been as close as my dad and I were), but being able to call her any time day or night for free really helps.

Congrats Rumfeeble :T:T

Has been manic in work last few weeks, so have not had time to catch up!

Well CD1 for me... was over a week late... even bought some tests on Friday... but was going to wait Wednesday. NO obvious signs and to be honest knew I wasn't... so did not get my hopes up at all, I am a real pesimist! My cycle is all over the place, 23 days and now 31 days... so when I thought I was BD on the right days, I wasnt even close!

Well I am off to catch up!!!

Bigs hugs to everyone and baby dust to everyone!

Mrs_T_M - It's best to not look to deeply into things. I went to see a geneticist to find out what I'm likely to pass on, and I was rather upset to find out there was a 50% chance of my children being deaf. Sometimes it's better not to know.

I was mostly just curious. Even though my allergies are not life threatening, I know some are. I'll take things as they come though.

Thanks for all the well wishes and thanks for all the hugs and support since I joined this thread back in January. You lot are amazing and i wish you could all get bfps with super sticky beans very soon.
I'm going to hang around/stalk this thread for a bit anyway as I would really miss all the antics on here if i left.
Lao-cat will i see you over on the less than 12 wks thread?

I am a bit scared to post over there but have a gp appointment tomorrow to confirm and then ill post over there!!

RG colour blindness only gets tranferred through the female line, and only appears in the sons of women carriers of the gene. So as long as your brother/mother's brother aren't RG colourblind, you won't be a carrier of the gene. If your hubby has a sister, she might pass it on to her sons. Same with your Dad's sisters. Hope that helps

Colour blindness is a sex linked trait on the X chromosome. Males have 1 X chromosome (since being male is technically XY) and females have 2 X chromosomes (being female is XX). Any affected male will pass on his affected X chromosome to ALL of his daughters, but none of his sons (they get the Y chromosome, which makes them male).

My father had the gene, and I'm a girl, which means he passed down his X chromosome, affected by the RG colour blindness, to me. I have one affected X chromosome and one normal X chromosome, meaning I do not exhibit the colour blindness.

My husband IS RG colourblind, which means he has one affected X chromosome and one Y chromosome. If we have a girl (XX), she will be a carrier, since she MUST carry her fathers X chromosome (he's only got one to pass on, so all girls we have will carry it). Since I have one normal and one affected X chromosome, 50% of our girls will display RG colour blindness. The other 50% will be carriers, therefore will be able to pass it on to their kids, but will not display the trait.

50% of our boys will display RG colour blindness. Their dad will pass along his Y chromosome to all of our boys, but there is still a 50% chance of them receiving the affected X chromosome from me. The other 50% of our boys will be completely unaffected and thus will NOT be able to pass it down to their children.

*Whew* Sorry about the mini-genetics lesson, but genetics was what I specialised in while getting my degrees and I enjoy working with genetics. RG colour blindness is a simpler one of the traits that can be passed down. Full colour blindness however deals with multiple alleles on multiple chromosomes, thus is more difficult to have.

Most traits (eye colour, hair colour, etc) are controlled by so many alleles in humans it's almost impossible to predict without a full genetic panel, and even then it's difficult to pinpoint.

Sorry, hope this post doesn't come across as "rantish" I don't mean it in that way.

Haemophilia is another X linked trait that is passed down and displayed in the exact same way that is described above, but neither of us have any incidence of it in our families, thank goodness.

Also forgot to add the bit that RG colour blindness is a recessive sex linked trait, therefore, any "normal" X chromosome that our girls have will take over and mask the affected X chromosome, which is why they will not display the trait. Males that have the gene do not have a "normal" X chromosome to take over, so they will display it. For females to display RG colour blindness, they must have 2 affected X chromosomes.

Wow mammouth post ! I stand corrected, i was referring to my genetics lesson from uni too (i'm a nurse), but i don't think we ever looked at the case of the male and female having the dodgy gene ! My brother is rg colourblind and it has been quite disabling for him when choosing his profession, not to mention the trouble it caused him at school when having to colour things in the right colour. My mum always put sticky labels on our colouring pencils to help him.

No worries! I just hope that it didn't come across as being haughty! Lots of things I say come out that way, even when I definitely don't mean for it to.

Since your brother has it, your mom is a carrier, which means you have a chance at being a carrier.

I just graduated (well, I say just, but my last course ended in May '11! Eek!) and I do absolutely nothing with my degrees for the most part. It's just a piece of paper that sits on the shelf collecting dust. When I was in the states I would substitute teach and tutor math, science, history and some basic skills (reading clocks, which I have trouble with at times as well, and basic literacy skills). I'm very strong in the maths and sciences, as well as history (which is weird), and although I love reading (extreme visual learner), I have difficulty grasping grammar and writing properly. Sometimes I miss teaching and tutoring, other days I don't. We plan on home schooling, so I'll be back to it before long (hopefully!) anyway.
