In pea plants, the gene for the color of the seed has two alleles. In the following Punnett
square shown below, the dominant allele (Y) represents yellow and the recessive allele (y)
represents green.
Female Plant Parent One
Phenotype = Yellow
Genotype = Yy
Male Plant Parent Two
Phenotype = Yellow
Genotype = YY
Based on the Punnett square, what percentage of offspring would be expected to have
yellow seeds?

100%

Explanation:

since the only chance to not have yellow phenotypes is to have 2 "y's", all the offspring will have yellow peas since the genotypes each have a "Y" and one has two.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
