Question

A. meiosis

B. uniformity

C. gametes

D. genetic diversity

Please Help me answer i wasnt really sure about this question...

Answer 1

The answer is D., ask Charlie Darwin if you want proof.

In biology, meiosis is the process that allows one diploid cell to divide in a special way to generate haploid cells in eukaryotes. The word "meiosis" comes from the Greek meioun, meaning "to make smaller," since it results in a reduction in chromosome number.

Meiosis is essential for sex. It therefore occurs in most eukaryotes, including single-celled organisms. meiosis is the process that produces genetic variation.

A gamete is a specialized germ cell that fuses with another gamete during fertilization (conception) in organisms that reproduce sexually. In species which produce two morphologically distinct types of gametes, and in which each individual produces only one type, a female is any individual which produces the larger type of gamete -- called an ovum (or egg) — and a male produces the smaller type — called a spermatozoon (or sperm cell) in animals, and a pollen grain in higher plants. Gametes from a mature diploid individual are produced in the gonadal tissue through meiosis.

Genetic diversity is a characteristic of ecosystems and gene pools that describes an attribute which is commonly held to be advantageous for survival -- that there are many different versions of otherwise similar organisms. For example, the Irish potato famine can be attributed in part to the fact that the genetic distance of all potatos in the country was very low - they were to uniform , making it easier for one virus to infect and kill much of the crop.

However, a population that is reproducing with mutations and crossing-over will produce a genetic diversity.
