Hope this helped! This is called a punnett square, it calculates the percentages of phenotype outcomes. Some are more difficult than others, but this is pretty basic, just be sure to study about this.
Answer:
C.) Disruptive selection
Explanation:
Disruptive selection is also called as diversifying selection. Here, two or more extreme phenotypes are preferred over the intermediate phenotype. Since more than one phenotype is preferred here, the genetic diversity of the population increases over generations.
For example, in lobsters alpha males are able to successfully mate by using force. Smaller males can also sneak in alpha males's territory and successfully mate. Hence, both alpha males and small males will be preferred over medium sized males in lobsters increasing the overall genetic diversity of population.
The tricuspid valve has three cusps that are essential components of the valve. (Hence "tri-" in tricuspid. ) The semilunar valve is called semilunar because each semilunar valve has cusps in the shape of half moons. Hope this helps to contrast their structure!
