PLEASE PLEASE PLEASE HELPPP DUE VERY SOO In dogs, the gene for fur color has two alleles. The dominant allele (F) codes for grey fur and the recessive allele (f) codes for black fur. 3) The f e m a l e d o g is h e terozygous. The m a l e d o g is h o m o z yg ous recessive. Figure out the phenotypes and genotypes of their possible puppies by using a Punnett Square.

Genotypes:

FF: 0%

Ff: 50%

ff: 50%

Phenotypes:

Black fur: 50%

Grey fur: 50%

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.
