Kingdom- a country, state, or territory ruled by a king or queen.

Species- a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial, e.g. Homo sapiens.

Prokaryote- a microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialized organelles, including the bacteria and cyanobacteria.

Eukaryote- an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaea.

Meiosis is a process that produces gametes. Using the diagram, what do you notice about the cells produced in meiosis?
Verizon [17]

Answer:

<u><em>The correct option is C) Meiosis produces 4 daughter cells each with half the number of  chromosomes of the original cell.</em></u>

Explanation:

There are two main processes by which cell divides:

1) Mitosis

2) Meiosis

All the cells of the body divide by the process of mitosis except the sex cells.<em> Sex cells divide by the process of meiosis.</em>

Meiosis can e described as a type of cell division in which four daughter cells are formed each having half the number of chromosomes as the parent cell. This is because the cell has to attain half of the maternal and half of the paternal chromosomes at the time of fertilization.

Crossing over and independent assortment are the phenomenon of meiosis which bring genetic diversity among parent and children.
