Summary
This document discusses the different types of cells, including somatic and gamete cells, as well as the processes of reproduction and genetic inheritance. It covers topics such as homologous chromosomes, autosomes, sex chromosomes, sexual reproduction, fertilization, diploid and haploid cells, meiosis, and gametogenesis.

Somatic Cell:-Also called body cells, these make up most of your body tissues and organs. Gamete:-Sex cells-ova (eggs) in females and spermatozoa (sperm) in males. Homologous Chromosome: -Two chromosomes, one inherited from the mother and one from the father, that have the same length and general...
Somatic Cell:-Also called body cells, these make up most of your body tissues and organs. Gamete:-Sex cells-ova (eggs) in females and spermatozoa (sperm) in males. Homologous Chromosome: -Two chromosomes, one inherited from the mother and one from the father, that have the same length and general appearance. Autosome:-Chromosomes that contain genes for characteristics not directly related to the sex of an organism. Sex Chromosome:-Chromosomes that directly control the development of sexual characteristics. Sexual Reproduction-Involves the fusion of two gametes, resulting in offspring that are a genetic mixture of both parents. Fertilization- The fusion of an egg and sperm. Diploid- A cell that has two copies of each chromosome, one from the mother and one from the father. Haploid:-A cell that has only one copy of each chromosome. Meiosis-A form of nuclear division that divides a diploid cell into haploid cells. Gametogenesis-he production of gametes. Sperm:-The male gamete. Egg-The female gamete. Polar Body-Cells with little more than DNA that are eventually broken down.
