Which genetic variation is shown below?
Leno4ka [110]

Answer:

This Punnett square shows<u> incomplete dominance.</u>

Explanation:

The homozygous red flower has two dominant red alleles, and these are represented by the letters RR. The homozygous white flower is represented by rr. Their offspring are all heterozygous Rr, and they have pink flowers. This is the first filial generation, or F1. When the F1 generation cross-pollinates, their offspring will be RR, Rr, and rr in a 1:2:1 ratio. Some of their offspring (the F2 generation) will inherit two R alleles, some will inherit two r alleles, and some will inherit both.

(i) An allele is a variant of a gene, can either be short or tall.

Dominant = the tall allele that "trumps" the short allele. if a dominant and recessive allele is present (heterozygous) then the dominant phenotype will be shown.

(ii) David's eyes are Brown

(iii) Sarah's eyes are blue

(iv) David - B, b

Sarah - b, b

(v) Possible genotypes include Bb and bb. These give the phenotypes of brown eyes or blue eyes.

(vi) The chance for blue eyes is 50% (or 1:1 ratio)
