Blood Group Ratio

Post by chikis » Sun Nov 13, 2011 2:58 pm

A man with blood group A (TAP) married a woman with blood group O (pp). Which of the following is the probable ratio of the blood groups of the offspring? A. 1:1 B. 3:1 C. 2:1:1 D. 1:2:1 E. 4:1. Any one who is sure of the correct answer from the options should do well by giving such option with good explaination. The person if he can should go further in detail saying all he knows about blood and blood groups. Moreover, any person who has something to say about the question should do so without hesitation. Am waiting forward for replies. Thank You.

Interesting, how cheeky you are (OK, now I understand your nickname). When you're asking us to answer your homework, you do not come with humbleness, but instead you bumptiously ask us to provide answer with good explanation without hesitation.

Draw your Punnet square or keep waiting.

Cis or trans? That's what matters.

you could both either be A or O.

Genes in humans contain two alleles. One allele you get from mom, and one allele you get from dad. Alleles can be dominant (expressed when present), or recessive (only expressed in the absence of a dominant allele). A alleles are dominant over O alleles; O alleles are recessive to both A and B blood types.

I still don't understand how and the the procedure to use in answering this question.
Maybe somebody should refer me to a web address or a link where I will take my time to read more about facts relating to blood and blood groups.

Use punnet squares and calculate the ratio of possible outcomes. Consider the possible genotypes for both parents (is there only one, or more than one?). A quick wikipedia search on ABO blood groups will help you figure out how the genotypes correlate with phenotypes and what to expect.

Averaged out over 17 countries these are the percentage breakdown of blood types

Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, China, Ireland, South Korea, Netherlands, New Zealand, Poland, Sweden, UK, USA

O+ = 36%

A+ = 34%

B+ = 12%

AB+ = 5%

O- = 6%

A- = 6%

B- =<2%

AB- = <1%
