Answer to Question #142356 in Genetics for Aldo Bagaskoro

Question

The genotals for rabbit fur are as follows:
A. Dark gray: CC, CCCH, CCH, Cc
B. Chincilla: CCHCCH, CCHCH, CCHc
C. Himalayas: CHCH, CHc
D. Albino white: cc

What are the results of the crosses, what is the comparison of results, and what are their genotypes and phenotypes?
A. Dark gray (CC) with Chincilla (CCCH)
B. Dark gray (CCH) with Himalayas (CHCH)
C. Chincilla (CCHc) with Himalayas (CHc)

Answer 1

The task condition is incorrect.

A. Dark gray: CC, CCCH, CCH, CcA.

A. Dark gray (CC) with Chincilla (CCCH) but should be A. Dark gray (CC) with Dark gray (CCCH)

A. P. ( Dark gray) CC x CC^ch ( ( Dark gray)

F1 CC, CC^ch,CC,CC^ch

Genotypic ratio: 2/4 or 50% - CC, 2/4 or 50%-CC^ch

Phenotypic ratio: 100%-Dark gray

B. P. (Dark gray ) CC^h x C^hC^h ( Himalayas)

F1 CC^h ,CC^h ,C^hC^h ,C^hC^h

Genotypic ratio: 2/4 or 50% - CC^h, 2/4 or 50%-C^hC^h

Phenotypic ratio: 2/4 or 50% -Dark gray (CC^h), 2/4 or 50%- Himalayas(C^hC^h)

C. P. (Chincilla) C^chc x C^hc (Himalayas)

F1 C^chC^h, C^chc, C^hc, cc.

Genotypic ratio: 1/4 or 25% - C^chC^h, 1/4 or 25% - C^chc, 1/4 or 25% - C^hc, 1/4 or 25% - cc.

Phenotypic ratio: 2/4 or 50% -Chincilla (C^chC^h, C^chc), 1/4 or 25%-Himalayas (C^hc), 1/4 or 25%-Albino white (cc).

A. Dark gray (CC) with Dark gray(CC^ch) produce 2 genotype and 1 phenotypes.

B. Dark gray (CC^h) with Himalayas (C^hC^h) produce 2 genotypes and 2 phenotypes.

C. Chincilla (C^chc) with Himalayas (C^hc) produce 4 genotypes and 3 phenotypes.
