Answer:This relationship is an example of a morphological similarity reflecting a likely evolutionary link
Explanation:
Lungfish and Coelacanths are distinct from other fish because they are lobe-finned species.
Lately, major palaeontological studies proposed that Lungfish and Coelacanth form a monophyletic sister group that is related closely to the tetrapods.
A monophyletic group is a group of organisms that include all the descendants and they share a common ancestor.
Answer:
See the second attached image showing the gametes from the parent with the location of the centromere indicating the type of chromosome
Explanation:
According to the position of the centromere, chromosomes can be of 4 types namely:
- Metacentric
- Acrocentric
- Telocentric
- Sub-metacentric
A metacentric chromosome is a chromosome that has no short or long arm. The arms are equal in length with the centromere joining the two sister chromatids located at the center.
Acrocentric chromosomes have unequal arm lengths with the centromere skewed towards one end of the chromosome.
Telocentric chromosomes have their centromeres at one end of the chromosome.
Sub-metacentric chromosomes have unequal arm lengths but the centromere is not as skewed to one end of the chromosome length as found in acrocentric chromosome.
The only possible gamete from <em>aa bb</em> parent is <em>ab</em>. Recall that the allele <em>a </em>is located on a metacentric chromosome while allele <em>b </em>is located on acrocentric chromosome.
Think it’s answer D but it maybe B
hope this helps!!
sorry if it’s wrong
