We'll use humans as an example since it's simple and relevant.
<span>All healthy humans have 46 chromosomes (23 pairs of very similar chromosomes). When gametes are formed in meiosis, this number is halved, such that sperm and ovum have only 23 chromosomes (just one of each pair). When these gametes meet and fuse as a result of sexual reproduction, the 23 chromosomes from the ovum and the 23 chromosomes from the sperm combine to form the full set of 46. </span>
<span>Sometimes meiosis doesn't quite work perfectly, though. Downs Syndrome is an example of this (one gamete has both copies of chromosome 21, so after fusion with the other gamete there are 3 chromosome 21s!).</span>

Explanation:
Genetic factors are the determinant of social and biological traits. Aptitude is a genetic factor that can influence the personality of individuals.
<h3>What are the factors influencing personality?</h3>
Genetic factors can influence the overall personality of an individual as they reflect the attributes and the characteristics of the person.
Aptitude is related to fitness, and the ability born naturally for doing something. It is generally acquired and inborn and is passed from the genetics of the parents to their offspring.
Other factors like love, support and security are not hereditary factors that impact the character of a person and are not genetic dispositions.
Therefore, option D. <u>aptitude </u>is correct.

Answer:
The first two are more closely related to each other than they are to the third.
Explanation:
The question tells us that the first two organisms share many common characteristics with each other, this tells us that the first two are related. We can cross out answer choice a. The question also tells us that the first two have very few characteristics in common with the third organism. With this much info given, the answer choices left are:
- Relatedness of the three organisms depends on the characteristics the first two share.
- The first two are more closely related to each other than they are to the third.
- The first two are equally related to the third.
First choice doesn't make any sense, there is no correlation between the common characteristics of the first two with the 3 organisms as a group.
Second choice makes sense and logical.
Third choice is wrong since the question does not give us enough information to know the first two is equally related to the third.
The first two are more closely related to each other than they are to the third. Is the right answer.
