For the following problems, state whether or not the offspring can be produced and the reason why that is the case. a. An O child by mating two A individuals b. An AB child by an A and O mating c. An A child by and AB and a B mating This is a genetics question

Answer #1

a) An O child can be obtained by mating two A individuals if they are heterozygous (AO)

b) An AB child cannot be produced by an A and O mating because O individuals are always homozygous (OO).

c) An A child can be produced by an AB abd B mating if B is heterozygous (BO).

    ABO BLOOD TYPE The ABO blood groups in humans are determined by multiple alleles. A single gene can exist in any of three allelic forms: 14, Bor i. This inheritance of the ABO blood type displays codominance as well as complete dominance. The two codominant genes A and B code for production of antigen A and antigen B on the surface of red blood cells, and are both completely dominant to the recessive allele i. The chart below shows the...

    For these questions, you are using the A, B, and O to represent the alleles in this example. The ABO blood system works in a Mendelian fashion, but has 3 possible alleles at one locus (A, B, and O alleles). Each person can have only 2 of those alleles in their genotype. A and B are both dominant (and so can be co-dominant), and O is recessive to both A and B. So, for example, if you have B blood...

    In the ABO blood groups, there are A, B, O, and AB blood types. They are due to three alleles, IA, IB, and IO, with IAIA and IAIO having blood group A; with IBIB and IBIO having blood group B; with IAIB having blood group AB; and with IOIO having blood group O. Among many aboriginal American Indian tribes, the allele frequency of IB in the ABO blood groups is extremely low. In one sample of 600 Papago Indians from...

    In simple Mendelian inheritance alleles display a simple dominant/recessive relationship. There are many exceptions to Mendelian laws of inheritance. Most genes have more than two allelic forms and do not exhibit simple Mendelian inheritance. The human ABO antigens are an example of a multiple allelic trait. There are three ABO blood group antigens, IA, IB and i. The i allele is recessive to both IA and IB. A person who is homozygous ii has type O blood and does not...

How many alleles we as individual can we have in our DNA? Is this a typical example of monogenic trait? Digenic trait? Or trigenic trait? Is only one gene involved? Is A dominant over B allele? Is A dominant over O allele? Is B dominant over O...
