I believe the answer to this question is D, I am not sure though.
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
Cross: between two dihybrids

F1) 9/16 Black-furred individuals, D-M- (1/16 DDMM + 2/16 DDMm + 2/16
DdMM + 4/16 DdMm)
3/16 Brown-furred individuals, D-mm ( 1/16 DDmm + 2/16 Ddmm)
4/16 Gray-furred individuals, dd-- ( 1/16ddMM + 1/16 ddmm + 2/16 ddMm)
Answer:
In eukaryotes, ribosomes can commonly be found in the cytosol of a cell, the endoplasmic reticulum or mRNA, as well as the matrix of the mitochondria. Proteins synthesized in each of these locations serve a different role in the cell. In prokaryotes, ribosomes can be found in the cytosol as well.
