Question
In particular duck species, feather color is determined by 3 different pairs of alleles at 3 loci. The colors range from dark green to pale green. A male and female duck are both heterozygous for all 3 loci controlling coat color.
A) How many different phenotypes are possible in their offspring?
B) What is the probability of having an offspring with the darkest possible pigmentation?
C) What is the probability of having an offspring with the same genotype as either parent
D) What type of inheritance pattern is demonstrated by this example?
Explanation / Answer
Lets assume the alleles are ABC and abc.
As, the parents are heterozygous
Parental genotypes are:
AaBbCc X AaBbCc
