Answer:
4 allopatric
Explanation:
The formation of a new species can occur in several ways. One such process is the separation of two populations of a species geographically. The presence of any geographical barrier may separate the two populations from each other. These populations accumulate variations over time. After several generations, the members of these two populations can not interbreed successfully and are said to be reproductively isolated. The two populations are now two different species. This is called allopatric speciation.
Answer:
Yes
Explanation:
Homologous structures or similar structural features can be a result of common ancestry. DNA comparison and analysis between the species can be used to identify the common ancestor.
None of their children would have the disease, but they would all be carriers. Because the X-linked disease is recessive which mean that it is not the main base so if you use punett squares and would get that all of the genomes are Xx, Xx, Xx, Xx which show you that there is a 0% chance of them two people having a child with that disease but there children could have a child with that disease if they had a mate that had that recessive gene.
