Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d). A pigment-eye
Ivenika [448]

Answer:

PpDD and PpDd

Explanation:

Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d).

The <u>possible genotypes of a pigment-eyed, dimple-chinned person</u> would be  PPDD, PpDd, PPDd, PpDD while a blue-eyed person without a dimpled chin would have the genotype ppdd.

The genotype of a blue-eyed, dimpled chin child would be either of ppDd or ppDD, but in this case, the mother is ppdd and as such, the child cannot have two copies of D allele. Hence, the genotype of the child can only be ppDd.

In order for the child to have blue eyes (pp), it means that the father has to have the non-pigmented allele (p). This also means that the father is heterozygous for eye pigmentation (Pp).

<em>Hence, the genotype of the father is now limited to </em><em>PpDD</em> <em>and </em><em>PpDd</em>.

Select the correct statement about plant life cycles.
vagabundo [1.1K]

The right answer is A.

Meiosis is an important process in many organisms:

In angiosperms, plants with flowers, meiosis occurs for the production of cells of pollen grains (gametes, haploid cells).

In animals, meiosis is important because it is the mechanism of gametogenesis that produces eggs (oogenesis) and sperm (spermatogenesis).

In the fungi, meiosis produces spores, which by mitosis will give a haploid generation.

If an organism has a high biological fitness in one environment ,does that mean that it would also have high biological fitness
dsp73

The answer is NO. This is because different environments require different adaptations. A desirable trait in one environment may be inconsequential or detrimental in another environment. This is the reason also why evolution is continuous as natural selection acts on traits of a population to ensure desirable traits are retained with changes in the environment in a dynamic world.
