<u>N</u><u><em>atural selection acts on existing heritable variation</em></u>
Answer: Option C
<u>Explanation:</u>
Natural selection is a process that occurs in nature as a key to evolution. It also goes hand with the survival of the fittest. Nature always selects the best trait to survive or get accustomed to the surrounding by undergoing modifications.
It acts on the genotype of the existing generation and causes variation in the future generation. So the population over generations get to have acquired the variations in their body, structure so that it is adaptable to the surrounding.
Answer:
50%
Explanation:
In this case, it is imperative to know each genotype >>
1. Genotypes for leg trait
- LL: normal legs
- Ll: deformed legs
- ll: very short legs
2. Genotypes for fur trait
- BB: black fur
- Bb: brown fur
- bb: white fur
According to the data above, the parental cross is as follow:
BBLl X bbLl
The possible gametes for each parental genotype are as follow:
Parental 1 >> 1/2 BL; 1/2 Bl
Parental 2 >>1/2 bL; 1/2 bl
Punnett square to calculate the possible genotypes of offspring:
bL - bl
BL 1/4 BbLL - 1/4 BbLl
Bl 1/4 BbLl - 1/4 Bbll
In consequence, the expected proportion of offspring with deformed legs and brown fur (genotype BbLl) is 1/2, i.e., 50%.
Answer:
The cells circulate in the atmosphere, then joining together, and eventually, they clusters, (clouds) get too heavy, and rain falls.
