Allele Dominant or recessive? Trait description G dominant gray g recessive black 1. Baby mice produced from the cross between male gg and female Gg parents will include Choose genotypes and Choose phenotypes

Respuesta :

Allele will be both heterozygous dominant and homozygous recessive in the progeny in the ratio of 1:1 ie 50 per-cent chance of both the alleles be expressed.

Phenotype: 50 per-cent chance of both black and gray colour mice

Genotype: Gg, gg 1:1

Explanation:

Dominant G

Recessive g

Baby mice produced from the cross between:

gg X Gg

Gg gg Gg gg

Genotype would be Gg gg in the ratio of 1:1

Phenotype would be Gray if dominant heterozygous gene having a dominant allele  appear or black if recessive homozygous appears in the progeny mice. It will be in the ratio of 2:2.
