Answer:

All these three location provide some kind of barrier be it physical, geographical or due to limited resources and thus lead to speciation

Explanation:

Speciation is a process in which species get isolated from the main group and then become re productively isolated and diverge and hence form new species.

a) A rugged mountain terrain can become a physical barrier there by allowing speciation

b) A large open forest is extremely vast  is size and thus species which have traveled to far away distance may not come back and thus get separated there by causing speciation.

c) An island in the Ocean is itself an isolated geographical location . Once a species land on this island, it can never return back to the main group and hence lead to speciation.

In a particular family, one parent has Type A blood, the other has Type B. They have four children. One has Type A, one has Type
AlladinOne [14]

Answer:

The correct answer is -

Parental genotypes: AO & BO

Children genotypes: AB, AO, BO, and OO

Explanation:

In the human blood group system, more than two types of alleles are present that lead to the existence of four blood groups in the human population.

Here, A and B alleles are co-dominant while the O allele is recessive to both A and B alleles in the ABO system.

The cross depicting the genotypes of children is

IA IO

IB    IAIB    IBIO

IO   IAIO   IOIO

In this cross, we get the same result as given in the question -

One parent has A and the other has B type blood while the children have all four types of blood groups One has Type A, one has Type B, one has Type AB, and the last has Type O. It is possible only when parents are heterozygous in their genotypes and not expressing codominance.
