Below are the answers to the question on the article
1 MvSI is closely related to MvSn than it is to MvDsp1.in phylogenetic tree the closeness of the relationship between two or more species highly depend on their claim to share a more recent common ancestor. In this case the species MvSI and MvSn share a more recent common ancestor compared to their ancestry relationship with MvDsp1.
2 MvLf is equally related to MvSd as it is to MvS1. In this case MvSd and MvS1 are more closely related as they share a more recent common ancestor as they share a common internal node which shows the splitting apart of one common group into two. The parents of MvLf and those of both MvS1 and MvSd share a more recent common ancestor as indicate by the internal node. As a result a conclusion is made that MvLf is equally related to MvSd as it is to MvS1
3 Based on the life cycle, the reproductive isolation that limited of heterospecific sporadia would be considered prezygotic. Research indicates that in behavioral isolation,prezygotic barriers are in most cases responsible for prevention of conjugation from occurrence.
4 The formula of reproductive isolation (IS)= 1-(ph/pc). Where ph is equivalent to success in conspecific crosses and ph is equivalent to the heterospecific crosses. Thus RI-2 = 1-(0.15/0.2). Hence RI-2 is equal to 0.25
5 It is not possible for the measure of reproductive isolation to be negative as the numbers are made of probabilities. Probabilities are always positive in value.
6 There is a significant relationship between RI-1 and genetic distance. An increase in genetic distance leads to a decrease in reproductive isolation (RI-1).
7 There is a significant relationship between RI-2 and genetic ...
