The presence of a specific trait is genetically inherited. There are only two possible outcomes for this trait: An individual ei
Igoryamba

Answer:

D) Each parent contributes one allele for this trait  

Explanation:

All traits of individuals are determined by specific genes of that trait. For example, there is a certain gene for height, certain gene for eye color, face shape etc.

Genes are the units of hereditary, and for every trait there is one gene in every organism. However, one gene is present in two alternative forms called alleles in an organism. For example: There is a trait height, a person has two alleles for the height gene, one allele is for short height, and other allele is for tall height. The trait of tallness is dominant over the trait of shortness, Therefore, this person will have tall height.

Now the alleles are transmitted from parents to offspring. Every parent contributes one allele for a specific trait, in the process and transmit it to offspring.

The allele which will be dominant will be expressed while the one that is recessive will e suppressed.

Therefore, option D is the right answer.

Hope it helps!

Which of the following statements is consistent with the principle of competitive exclusion?
Marina CMI [18]

Answer:

D) Even a slight reproductive advantage will eventually lead to the elimination of the less well adapted of two competing species.

Explanation:

The competitive exclusion describes relationship between two species that compete for the limiting sources, and cannot coexist. It is enough for one species to have slightly advantage to be dominant over the other. As a consequence, other species (the weaker one) will be extincted (shift to a different ecological niche).
