Answer:
ecological dominants
Explanation:
In an ecosystem, organisms of same and different species are usually found. However, some organisms appear too commonly than others in that particular ecosystem. These commonly observed organisms (plants and animals) due to their large numbers are called DOMINANT species. An ecological dominant species is that which numerically outshines its competitors in an ecosystem.
A species may be dominant because it is better adapted to certain processes than Its competitors e.g. getting resources, disease resistance etc. or even deters its competitors. Hence, they appear large in number. This is the case of the abundance of pinyon pine and juniper trees along the desert slope of the sierra nevada mountains in california. In that ecosystem, these two plants dominate, hence, will be referred to as ecological dominants.

Answer:
50% (Answer Choice 3)
Explanation:
One important thing to keep in mind when solving sex-linked Punnett Squares is that males can never be carriers, since they have one X and one Y chromsome. Thus, it is only possible for females to be carriers, because they have two X chromsomes. Because of this, before solving the problem, you already know that 50% or less of the offspring can be carriers, thus eliminating two answer choices right off the bat. Now, the only way to find out whether 25% or 50% of the offspring are carriers is to solve the Punnett Square. The two female genotypes resulting from the cross is 
and . Since both offspring have only one allele for color-blindness, both are carriers, which means that the answer is 50%.
