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.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
