List the stages of parturition. Genetics: Solve the following genetics problem by determining how the following traits would assort. Use D/d for Rh. Remember Rh+ is dominant, and Rh- is recessive. Use A, B and O for blood types. Remember human ABO blood types are in a co-dominant system with O as the only recessive allele (both A and B are dominant).
The mother is type AB+ and the father is type B-. List all possibilities for each parent’s genotype using what you know from the information given so far (assuming you have only read this so far ).
Now assume that any dominant trait is heterozygous. What are the genotypes you will use for each parent?
Create a double square (dihybrid cross) to assort these two traits. Show your work.
What are the possible genotypes for each child? Provide a percentage (or a fraction) for each possible genotype.
What are the possible phenotypes for each child? Provide a percentage (or a fraction) for each phenotype.
Is there any possibility that a child will be born to these parents that will show the recessive phenotype(s) for either or both traits? Explain: Why or why not?
