Natural selection directs evolution as it results in adaptations in a given population.

Two pea plants,one with round green seeds $(RRyy)$ and another with wrinkled yellow $(rrYY)$ seeds,produce $F_1$ progeny that have round,yellow $(RrYy)$ seeds. When $F_1$ plants are selfed,the $F_2$ progeny will have new combinations of characters. Choose the new combinations from the following:
$(i)$ Round,yellow
$(ii)$ Round,green
$(iii)$ Wrinkled,yellow
$(iv)$ Wrinkled,green

All human races,such as Africans,Asians,Europeans,Americans,and others,might have evolved from a common ancestor. Provide a few pieces of evidence in support of this view.

The two versions of a trait (character) which are brought in by the male and female gametes are situated on

Who are the carriers of genes?

What is micro-evolution? Does it explain speciation?
