what is the phenotypic ratio results from a cross between a homozygous recessive individual and a heterozygous individual

Sagot :

The phenotypic ratio from crossing monohybrid between a homozygous recessive individual and a heterozygous individual is 1 : 1.

The recessive homozygous gene is the result of the fusion of two recessive genes from the two sex cells. The symbol for a recessive homozygous gene is two lowercase letters aa or aabb.

Heterozygous is a gene that has a pair of different alleles, so one is dominant and the other is recessive, so it is written with a combination of uppercase and lowercase letters, such as Aa or AaBb.

Crossing between a homozygous recessive (aa) individual and a heterozygous individual (Aa):

     a        a

A  Aa     Aa

a   aa     aa

Genotype ratio → Aa : aa = 1 : 1

Phenotype ratio → 1 : 1
