Answer:
The correct answer would be D.) It is carried out in cells that are involved in sexual reproduction.
Meiosis is type of cell division which results in the formation of four haploid cells from single diploid parent cell.
It is also celled reductional division as it reduces the number of chromosomes to half in all the daughter cells.
It is divided into two stages meiosis I and meiosis II. Meiosis I includes division of homologous chromosomes which results in the formation of 2 haploid daughter cells from one parent cell.
The two daughter cells undergo meiosis II during which sister chromatids are pull apart which results in the formation of 4 daughter cells each containing half the chromosomes of parent cell.
It takes place in cells that are involved in sexual reproduction that is, it results in the formation of haploid gametes from diploid precursor cells.
In males, it results in the formation of sperm cell and in females it helps in the formation of eggs.
In sexual reproduction, fusion of gametes results in the formation of diploid zygote that is, re-storage of diploid chromosome number.
Answer: lower reproductive potential
Explanation: Evolutionary psychologists focused on what today is sociobiological approach to sexuality shaping the pattern of human sexuality. This considers that women's parental investment in reproduction is greater than men's, because human sperm is more abundant in quantity than eggs, and the fact that women must carry their young in the womb for several months as well as nurture them for a considerable time after birth. This tends to make women more selective in their choice of mates than men and is seen as a limiting factor in regards to sexuality compared to men.
According to social learning theory however, sexuality is a learned behaviour which arise from studying our environments. The attitudes of parents and grown ups in the society tend to shape our perspectives and expectations which expressing sexuality is a part of.
