Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.

The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.

SVETLANKA909090 [29]

Answer:

a. M_D_ : 9/16 Black furred individuals

b. M__dd : 3/16 gray furred individuals (1/16 MMdd + 2/16 Mmdd)

c. mmD_ : 3/16 Brow-furred individuals (1/16 mmDD + 2/16 mmDd)

d. mmdd: 1/16 gray furred individuals.

Explanation:

Available data:

Dense pigment gene, D, codes for melanophilin.
D allele dominant over d.
Gene M/m is responsible for the production of the pigment
M is dominant over m
If D is present, M/m is expressed
If dd is present, M/m is not expressed
DDMM, DdMM, DDMm, DdMm --->Black fur
DDmm, Ddmm ---> Brown fur
ddMM, ddMm -----> Light gray fur
