Homework Answers
The number of allele combinations form any genotype can be calculated by 2N, where N is the total number of heterozygote genes in a genotype such as Aa or Bb. The given genotype is AaBB. As we can see we have only one heterozygote Aa, so the value of N is 1. The number of allele combinations will be 21 = 2. So it will form two allele combinations that are AB and aB.
The answer is B.

Genes A and B are linked. Individual plants homozygous for different combinations of these genes (AABB, aabb, AAbb, aaBB) were crossed at random to produce F1 plants. The F1 plants were self pollinated to produce the F2. The F2 progeny from six of the F1 self pollinations are listed below. Number of F2 plants in each phenotypic class F1 Plant-------------------AB--------------- Ab --------------- aB----------------- ab 1 --------------------------0 ----------------98 ---------------- 0------------------ 32 2 ------------------------- 64 --------------10 -----------------8...
