<span>If the parent's reproductive cells or gametes contain 12 chromosomes each, the number of chromosomes in the zygote is 24. Fertilization is the fusion of two haploid gametes and results in the creation of a diploid zygote. If two haploid gametes containing 12 chromosomes each fuse, the zygote will have 24 chromosomes (12 + 12 = 24).</span>
Answer:
The purpose of the organs of the male reproductive system is to perform the following functions: To produce, maintain, and transport sperm (the male reproductive cells) and protective fluid (semen) To discharge sperm within the female reproductive tract during reproduction
A confounding variable refers to an external effect, which modifies the influence of an independent and dependent variable. This extraneous effect is used to affect the outcome of an experimental design. The confounding variables can ruin the experiment and can generate unnecessary outcomes.
In the given case, confounding variables can be introduced by testing multiple hypotheses at a time and by using distinct kinds of soil in each of the samples.
Answer:
Meiosis II.
Explanation:
Meiosis may be defined as a type of cell division in which four daughter haploid cells are produced from the single diploid cell. Meiosis is also known as reduction division as the chromosome number is reduced to half as compared with the original parent cell.
Meiosis is divided into meiosis I and meiosis II. The meiosis is similar to mitosis as the each cells contain only one set of the homologous chromosomes.
Thus, the correct answer is option (3).
