Answer:
3 yellow : 1 green
Explanation:
Yellow seed allele (Y) is dominant over the green seed allele (y).
A cross between two true breeding parents is done: YY x yy
The F1 offspring would be heterozygous Yy.
<u>If the F1 is selfed (Yy x Yy) the expected ratios for the F2 generation according to Mendel's law of segregation would be:</u>
- 1/4 YY (yellow)
- 2/4 Yy (yellow)
- 1/4 yy (green)
So 3/4 seeds of the F2 would be yellow because they have a dominant Y allele, and 1/4 would be green.
The phenotypic ratio will be 3 yellow : 1 green
Answer: A. Only the strongest animals survive.
The theory of natural selection - the survival of the fittest suggests differential survival and reproduction of the organisms. This means the organisms that have better phenotypic advantage over the others likely to survive and reproduce in the adverse environment. Such phenotypic traits will be passed from the parents to the offspring and will promote the evolution of the species.
On the basis of the above description, the only the strongest animals will survive is the correct option.
