1.Cross one parent that is heterozygous for both beak color and feather color with a parent that is homozygous for both recessive traits. What are the genotypes of the parents? (Hint: Recall that the P generation includes a heterozygous parent with dominant traits and a homozygous parent with recessive traits.)Assume the following F1 generation:YyBb: 420Yybb: 80yyBb: 80yybb: 420Which offspring are the recombinant offspring in this cross?How far apart are Y and B
