Which represents the cross between parent plants if one is heterzygous and has yellow-colored pods and the other is homzygous and has green-colored pods? Yy ´ yy
YY ´ yy
Yy ´ Yy
yy ´ yy

The cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homzygous and has green-colored pods -  Yy yy

Purebred genotype:

Thus, the cross would be -  Yy yy

Its the first one

Yy is yellow (dominant) and heterozygous

yy is green (recessive)

with Yy and yy, you could only get 50% Yy(yellow) and 50% yy(green).  There is no way to make only yy or YY, and in order to make 100% Yy you would need one yy and one Yy

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
