Ans.

Angiosperms are vascular, flowering plants that produce seeds, enclosed in ovaries. Reproductive structures of angiosperms are present in flowers, which include male reproductive structures (stamens) and female reproductive structures (carpels).

Stamen includes anther (where pollen grains are produced) and filament, while carpel includes stigma, style, and ovary (where eggs are produced).

Thus, the correct answer is 'flowers.'

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

soldier1979 [14.2K]

answer:

by having a high genetic level of melanin in your skin, you're skin is more protected from the ultra violet sun rays. Darker skinned races have more melanin present, these races originate from hot countries where sunlight is often present; the production of melanin in their skin allows them to reflect and inhibits they're skin from becoming extremely damaged. Light skinned races don't have a large amount of melanin due to they're native countries lacking sunlight. This is an evolutionary adaptation of the human race.
