Coat color in rabbits is under the control of a single gene with

Mashcka [7]

Answer: a) Cch x Ccch

b) Ccch x Cc

c) Cch x cchch

d) cchc x chc

Explanation:

Data:

Coat color in rabbits is under the control of a single gene with

four alleles: C (full gray color); cch (chinchilla, light gray); ch

(Himalayan, white with black extremities); and c (albino, absence

of pigmentation).

The dominance hierarchy is represented as: C >cch > ch > c.

Possible genotypes:

For full gray color: CC (Gray), Ccch (Gray-2), Cch (Gray-1), Cc (Gray-3). The allele "C" dominates over the other three alleles, so in every combination where "C" is present, the animal will be fully grayed.

For light gray color/Chinchilla: cchcch (Chinchilla), cchch (Chinchilla-1), cchc (Chinchilla-2). The allele "cch" dominates over "ch" and "c", but not over "C". So if the allele "C" is combined with "cch", the animal will be fully grayed, but in any other combination with "cch", the animal will be light grayed.

For white with black extremities/Himalayan: chch (Hymalayan), chc (Hymalayan-1). The allele "ch" that determines the Himalayan color is only dominant over the allele "c". But in combination with any other allele, "ch" behaves as a recessive one.

For albino: cc. In the presence of any of the other alleles, the allele "c" always behaves as a recessive one. The only possibility of getting an albino animal is if "c" combines with another "c".

Which enzyme is not working correctly if the dna had more than nomal level of mutations?

alina1380 [7]

Answer:

The name of the enzyme is DNA POLYMERASE.

Explanation:

DNA replication is the process by which the DNA reproduce itself. During the process of replication, the blocks of nucleotide that are been added are checked constantly by mean of proof reading in order to ensure that all the nucleotide are properly paired. The enzyme that carried out the work of proofreading and subsequent repair is DNA polymerase enzymes. The activities of the enzyme ensures that no mutation occur in the DNA strands that are been produced.
