How do analogous structures evolve?
PSYCHO15rus [73]

Answer:

" Often, two species face a similar problem or challenge. Evolution may then shape both of them in similar ways — resulting in analogous structures. For example, imagine two flower species that are not closely related, but both happen to be pollinated by the same species of bird."

Why is meiosis important for organisms? It allows for genetic variation among organisms. It determines which genes are dominant
Studentka2010 [4]

Meiosis is important for organisms since it allows for genetic variation among organisms.

<h2>Further Explanation</h2><h3>Cell division</h3>
  • Cell division is the process in which cells undergo division to form other new cells.
  • There are two types of cell division;
<h3>Mitosis Division  </h3>
  • Mitosis is a type of division in which a parent cell undergoes division to yield two daughter cells that are similar to the parent cells.
  • The daughter cells have equal number of chromosomes as the parent and are identical to the parent.
  • This type of cell division normally occurs in somatic cells of organisms and facilitates growth and development of organisms.
<h3>Meiosis division</h3>
  • Meiosis division is a type of division that occurs in gamete cells where a parent cell divides into four daughter cells that differ from the parent cells in terms of the number of chromosomes.
  • In meiosis the daughter cells have half the number of chromosomes as the parent cells.
  • Meiosis occurs in the gamete cells and facilitates sexual reproduction in living organisms.
  • Meiosis occurs in two phases, that is, meiosis I and meiosis II
  • During the process of meiosis several processes occurs that cause genetic variation among organisms.
  • These processes include, crossing over, independent assortment of genes, among others.
<h3>Crossing over  </h3>
  • Cross over is the process that occurs during the prophase I phase of the first stage of meiosis known as meiosis I.  
  • During the process of crossing over, genetic material is exchanged between homologous chromosomes which enhances the genetic variation in organisms.

Keywords: Cell division, meiosis, crossing over, genetic variation

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>.
