Explanation:
Answer:
e. Because gene flow between populations prevents genetic divergence in sympatry.
Explanation:
Speciation requires genetic divergence between populations of a species to isolate them reproductively. however, when present in the same habitat, gene flow between populations of a species does not allow their reproductive isolation and thereby, prevents the formation of new species. These populations need strong episodes of disruptive selection for their reproductive isolation.
On the other hand, two geographically isolated populations can not interbreed and thus, there is no gene flow between them leading to their genetic divergence and speciation. So, allopatric speciation is more common than sympatric one.
All of them, they are all very important factors to test for the identifying
Answer:
1/64 = 0.015625
Explanation:
Genotype of parents: aa bb Cc Dd Ee x aa Bb Cc dd Ee
To calculate the frequency of the child with desired genotype, individual frequency of desired genotype can be calculated followed by application of product rule.
aa x aa = All aa
bb x Bb= 1/2 bb: 1/2 Bb
Cc x Cc= 1/4 CC: 1/2 Cc : 1/4 cc
Dd x dd = 1/2 Dd: 1/2 dd
Ee x Ee= 1/4 EE: 1/2 Ee: 1/4 ee
Expected frequency of the child with desired genotype= 1 aa x 1/2 bb x 1/4 cc x 1/2 dd x 1/4 ee = 1/2 x 1/4 x 1/2 x 1/4 = 1/64 = 0.015625
