Question

single heterozygous condition in dihybrid cross ?​

Answer 1

Answer:

9:3:3:1

A dihybrid cross tracks two traits. Both parents are heterozygous, and one allele for each trait exhibits complete dominance *. This means that both parents have recessive alleles, but exhibit the dominant phenotype. The phenotype ratio predicted for dihybrid cross is 9:3:3:1.

Answer 2

$\huge\boxed{\underline{\mathcal{\red{A } \green{N } \pink{S } \orange{W } \blue{E } \pink{R }}}}$

A dihybrid cross allows us to look at the pattern of inheritance of two different traits at the same time. For example, say we are crossing two pea plants. ... This means that all of their offspring will be heterozygous for those traits (they each have one dominant allele and one recessive allele).
