Answer:

9:3:3:1

Explanation:

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. (There's a calculator on google that show the outcomes just to let ya know) hope it's correct .

Answer:

when you perform a dihybrid cross with two heterozygous individuals for the two traits, what is the expected phenotypic ratio?

HhBb x HhBb= HHBB, HhBb, HhBb, hhbb

3:1

Explanation:

This results into two homozygous and two heterozygous, one homozygous is dominant while the other is recessive, although out of the four offspring three are dominant over one recessive

Gelneren [198K]

In chromatin, substitution mutations are most common in linker regions. Option d is the correct answer.

Mutation by substitution When one nucleotide base is replaced by another, this occurs. Mismatch mutation A type of substitution mutation in which a single nucleotide is replaced, resulting in the coding of an incorrect amino acid, which usually results in a malfunctioning protein. Silent mutations are the result of genetic code redundancy (degeneracy): This is false, as silent mutations are the result of a base substitution that has no discernible effect on a protein's amino acid sequence.
