Answer:

D. natural selection

Explanation:

<em>Natural selection is an evolutionary process in which organisms that are better adapted to changes in the environment survive and contribute more to the subsequent generations in terms of reproduction.</em>

The weak organisms gradually phase out of the population because they are weakly adapted to changes in the environment. Hence, they are not able to survive and or reproduce.

<u>Hence, processes whereby some animals are better able to survive and reproduce under changing environmental conditions ahead of others are natural selection processes.</u>

A maize plant with genotype Aa Bb produces the following gametes 100 Ab 45 AB 106 aB 50 ab This tells us that the two genes are
bogdanovich [222]

Answer:

True

Explanation:

The linkage relation of two genes can be determined on the basis of calculating recombination frequency.

If the recombination frequency value is greater than 50% then the genes are not linked and if the value is less than 50% then the genes are linked.

In the given question, the  crossover gametes formed will be Ab = 100

and aB= 106.

Therefore,

\dfrac{recombinant\ progenies}{ Total\ progeny}\times 100\\\\\dfrac{100 +106}{100+106+45+50}\times 100\\\\=\dfrac{206}{301}\times 100\\\\= 68.43\%

Since the recombinant frequency value is larger than 50% therefore the genes do not show linkage.

Thus, True is the correct answer.
