1:1:1:1:1:1:1:1 ratio is the expected outcome of a heterozygous (BbGgCc) and a homozygous recessive (bbggcc) cross.
Because in heterozygotes, both alleles are transcribed and translated.
The genotype of the P (parent) generation can be done by crossing an offspring from the F1 (first filial) generation with one of the gametes from the P generation and then calculating the genotypic and phenotypic ratios. Such an experiment is called a back cross

The expected genotypic ratios for a dihybrid cross is 9:3:3:1, and for a monohybrid cross is 1:2:1.
becouse you touch yourself at night.
The genotypic ratio of a cross of Aa and Aa is: one AA, one aa, and two Aa. Or 1:2:1

It does.. But you knew anything you would try to answer it 👏
representation of genotypes of a pair of contrasting traits of a character in the form of ratio is referred as genetic ratio. in this ratio the three different genotypes are represented- homozygous dominant genotype:heterozygote genotype:homozygous recessive genotype in case of a monohybrid cross ( either normal cross,reciprocal crosses of Mendel or back cross or test cross ratios) and for dihybrid crosses- dominant genotype:recombinant genotypes:recessive genotypes are represented. For instance monohybrid genotypic ratio is 1:2:1 and back cross/test cross ratio-1:1 For dihybrid genotypic ratio 1:2:2:4:1:2:1:2:1 It may differ in different cases according to T.H.Morgan.Bateson, punnet, Garrod etc.
