Question

the expression of one of the character in F1 generaton in F1 and both of the traits in F2 can be explained by

Answer 1

Every member of the F1 generation is heterozygous and the phenotype of theF1 generation expresses the dominanttrait. Crossing two members of the F1 generation produces the second filial (F2) generation. Probability theory predicts that three quarters of the F2 generation will have the dominant allele's phenotype.
