Answer:
D) The chromosomes are composed the two sister chromatids and are lined up along the equator of the cell.
A condition in which a single mutant gene affects more than one distinct characteristic of an individual is referred to as Pleiotropy.
<h3>What is Pleiotropy?</h3>
- Pleiotropy occurs when one gene influences two or more seemingly unrelated phenotypic traits.
- Such a gene that exhibits multiple phenotypic expressions is called a Pleiotropic gene.
- Pleiotropy can arise from several distinct but potentially overlapping mechanisms, such as gene pleiotropy, developmental pleiotropy, and selectional pleiotropy.
- An example of pleiotropy is phenylketonuria.
- So, when a single trait mutant gene controls more than one trait it is called Pleiotropy and it can cause the various syndrome.

The sodium and potassium ions are transported using a sodium potassium pump the process of moving sodium and potassium ions across the cell membrane.
Answer:
Phylogenetic relationships
1. includes all descendants from a single common ancestor >>> monophyletic group
2. does not share any common ancestry but represents convergent evolution >>> polyphyletic group
3. includes some but not all descendants from a single common ancestor >>> paraphyletic group
Explanation:
A monophyletic taxon is a collection of organisms that have the same most recent common ancestor, thereby including an ancestor and all its descendants. Examples of monophyletic groups are angiosperms, mammals, insects, etc. A paraphyletic group is composed of some (but not all) the descendants of the most recent common ancestor. An example of a paraphyletic group includes fish and lizards. Finally, a polyphyletic taxon is composed of a group of organisms that do not contain the common ancestor of all the members of the group. An example of a polyphyletic group is composed of birds and mammals, (which constitutes a group of warm-blooded animals).
