In cats, the Dense pigment gene, D/d, codes for melanophilin, a protein involved in the transportation and deposition of pigment
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

Cross: between two dihybrids

Parental)         DdMm     x     DdMm

Phenotype) Black-furred      Black-furred

Gametes) DM, Dm, dM, dm   DM, Dm, dM, dm

Punnet Square)    DM        Dm         dM          dm

             DM       DDMM    DDMm   DdMM   DdMm

             Dm       DDMm    DDmm   DdMm   Ddmm

             dM        DdMM    DdMm    ddMM   ddMm

             dm        DdMm    Ddmm    ddMm   ddmm

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)

Mesosphere, 50-80km, the temperature here reaches -140 Celsius shooting stars are formed here

Stratosphere, 12-50km produces the mayor part of the atmospheric ozone, some army planes reach this later
