A Graphic used to help predict the possibility
of different gametes

Punnett squares and probability.

A Punnett square can be used to predict genotype and phenotypes of offspring from genetic crosses.

Each parent produces one kind of gamete, resulting in an F{1} generation with a dominant yellow phenotype and the genotype Yy

tissue

explanation:

it is actually formed by geoup of cells which is tissue

b is dominant over the allele for the white fur.
