Answer:

C. Disruptive Selection

Explanation:

Disruptive selection occurs when two extremes of continuous variation are favored more than intermediate traits.  

The extremes of continuous variation exhibited in this species of snail is the color of their shell which allows them to blend with the background of their habitat.  

The shady forest of the habitat makes the dark-shelled individuals to be better hidden from bird predators, while the light-shelled individuals are better hidden in well-lit brushy edge areas. This disruptive coloration exhibited by both individuals makes both individuals of this species of snail less vulnerable to predation.  

Both individuals of this species both extremities would naturally survive in this habitat as snails with intermediate extremities would be highly preyed on since there is no area of intermediate brightness in the habitat to make them invisible to predators

Inheritance patterns cannot always be explained by Mendel’s models of inheritance. If a pair of homologous chromosomes fails to
Talja [164]

The correct answer is: a. n+1, n+1, n-1, n-1

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during mitosis  or meiosis. There are three forms of nondisjunction:  

1. failure of a pair of homologous chromosomes to separate in meiosis I ,  

2. failure of sister chromatids to separate during meiosis II, and  

3. failure of sister chromatids to separate during mitosis.

As a consequence of nondisjunction abnormal chromosome numbers appears. If nondisjunction occurs during the meiosis I (anaphase I), this means that at least one pair of homologous chromosomes did not separate. The consequence is two cells that have an extra copy of one chromosome and two cells that lack that chromosome.

<span>Meiosis helps prevent mutations from occuring over and over again. In Meiosis process, the number of chromosomes during reproduction was caused in half. During this process, the chromosomes that could potentiall caused mutation could be tossed out and therefore reduce its chance from happening</span>
