Answer:  The species are poorly related to each other.

Darwin gave information for evolution as "descent with modifications" it involves a process in which species change and gives rise to a new species over generations. He proposed that the evolutionary history of life forms a branching tree with many level as a new species evolve. All species can be traced back to a common ancestor. Each newly evolved species will have one or more characteristics in common as that of the old species.

In species with no common ancestor will not have any similar characteristic in common such species cannot be evolutionary linked and cannot be placed and linked in an phylogenetic tree.

Brown mice disappear from the mouse population for two generations and then reappear in the third generation. Give two possible
gizmo_the_mogwai [7]

Answer:

The trait is inherited in the homozygous recessive pattern

Possible mating is between two heterozygous individuals

Explanation:

One possible explanation for this is that the trait for this brown mice has to inherited in the homozygous recessive condition. It is possible for this trait to skip two generations and then reappear if it has to be inherited in the homozygous recessive condition.

Another explanation to complement the first is that for this trait to reappear, there was mating between two heterozygous individuals (with one allele being domiant and the other being recessive). It is possible that all matings within the two skipped generations was between an heterozygous and a homozygous dominant or between two homozygous dominant individuals which will not produce the brown mice..
