Sexual Reproduction, Meiosis, and DNA

Sexual Reproduction, Meiosis, and DNA. Sexual Reproduction. During sexual reproduction , two sex cells, sometimes called an egg and a sperm, come together. Sex cells are formed from cells in reproductive organs. Sperm are formed in the male reproductive organs.

Equilibria in populations. Population data. Recall that we often study a population in the form of a SNP matrix Rows correspond to individuals (or individual chromosomes), columns correspond to SNPs The matrix is binary (why?)

Meiosis

Meiosis . Foundation for Sexual Reproduction. Chromosome Characteristics. Diploid set for humans; 2n=46. Autosomes; homologous chromosomes, one from each parent (humans=22 sets of 2). Sex chromosomes (humans have 1 set). Female-sex chromosomes are homologous (XX).

Mitosis

Mitosis. Genes and Proteins. Proteins do the work of the cell: growth, maintenance, response to the environment, reproduction, etc. Proteins are chains of amino acids. The sequence of amino acids in each protein is coded in the DNA as a specific sequence of A, C, G and T bases: a gene.
