Hello students, single dominant gene causes the feathers while homozygous recessive causes the unfeathers.
00:26
When there are heterozygous at both locius and are crossed, then the genotype of parent will be aab and it is crossed with the other parent.
00:51
Here capital a or the a represents the allele at locus 1 while b represent the allele at locus 2.
01:09
Now when this fuses the allele will be ab, ab, small a capital b and small a small b.
01:21
Similarly here also a small b, capital a small b.
01:30
Capital b and small a capital b and small a and small b.
01:38
Now when it is crossed the offsprings will be we will draw the ponent square that is a b a b small a and small b here also a b capital a capital b small a capital b small a capital b and small a and small b.

Capital a, capital a, capital b, small b, capital a, capital a, capital a, capital b, capital a, capital b, capital a, capital b and small b...
