What happens to the alleles between the P generation and the F2 generation?

In the P generation, one parent is homozygous dominant and the other parent is homozygous recessive. In the F1 generation, the product of a cross between the P generation, the offspring are all heterozygous. In the F2 generation, the product of a cross between the F1 generation, the expected result is 1/4 homozygous dominant, 1/2 heterozygous, and 1/4 homozygous recessive.

What is the genotypic ratio for a tetrahybrid cross?

1:1:1:1:1:1:1:1 ratio is the expected outcome of a heterozygous (BbGgCc) and a homozygous recessive (bbggcc) cross.


The offspring of two parents that are heterozygous for a given trait have a percent chance of being homozygous for that trait?

This would result in 1 heterozygous offspring. You can think of it like this: If the first parent is homozygous it would have AA alleles, the second heterozygous parent would be AB. When they mix genetically it would result in 4 combinations: AA, AA, AA, AB. As there is only one B there can only be one heterozygous offspring. This is not expected it is certain.


What is the probable genotype for the two parents of a cross between two pea plants?

Crossing between two parents is done to combine noble characters of parents into the next generation. Suppose a dwarf pea plant has better quality of pods and its tall counterpart has more number of pods per plant then a plant breeder may think of combining these two characters into its hybrid. The genotype for these tall & dwarf parents with variable pod quality and quantity may be designated as - Tall parent --- ppTT & dwarf parent -- PPtt
