Question

in a group of koi fish, some individuals have red eyes and others have black eyes. in this group, the gene for the eye color trait has two alleles. the allele for black eyes (e) is recessive to the allele for red eyes (e). this punnett square shows a cross between two koi fish. punnett square with e, e on top and e, e on side, resulting in ee, ee, ee, ee what is the expected ratio of homozygous recessive to heterozygous to homozygous dominant offspring genotypes? choose the most likely ratio. 0:4:0, 0:0:4, 4:0:0

Explanation:

Step1: Identify Genotypes

In the Punnett square, all offspring genotypes are \( ee \). \( ee \) is homozygous recessive (since \( e \) is recessive). There are 0 heterozygous (\( Ee \)) and 0 homozygous dominant (\( EE \)) genotypes.

Step2: Determine Ratios

Count the number of each genotype: homozygous recessive (\( ee \)) = 4, heterozygous = 0, homozygous dominant = 0. So the ratio is \( 4:0:0 \).

Answer:

4:0:0
