In rabbits, full coat color (c) is the dominant trait. a second allele, chinchilla (cch) is recessive to full coat color. himalayan coat color (ch) is recessive to chinchilla and full coat colors, and albino (c) is recessive to all coat colors. if a homozygous chinchilla rabbit mates with a heterozygous himalayan rabbit, what is the expected phenotypic ratio in their offspring? a) 2 chinchilla : 2 himalayanb) 3 chinchilla : 1 himalayanc) all chinchillad) 2 chinchilla : 1 himalayan : 1 albinoe) cannot be determined from the information given

c) All chinchilla

Explanation:

The dominance relationship between alleles is:

Full color (C) > chinchilla (cch) > himalayan (ch) > albino (c)

Cross between a homozygous chinchilla rabbit and a heterozygous Himalayan rabbit

The genotypes of the parents and the gametes they produce are:

With this information we can complete a Punnett Square to determine the genotypes and phenotypes of the expected offspring.

There are only 2 possible genotypes for the offspring: cch ch and cch c.

Because both the ch and the c alleles are recessive to cch, the whole offspring will have a chinchilla (cch) phenotype.

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.
