Meiosis
Term | Definition |
---|---|
genes | sequence of DNA that codes for a protein and thus determines a trait |
homologous chromosomes | chromosomes in which one set comes from the male parent and one set comes from the female parent |
gamete | sex cells |
haploid | a cell that contains only a single set of genes (HALF) |
segregation | separation of alleles during gamete formation |
independent assortment | genes for different traits can segregate independently during the formation of gametes |
fertilization | process in sexual reproduction in which male and female reproductive cells join to form a new cell |
diploid | a cell that contains two sets of homologous chromosomes, (DOUBLE) |
meiosis | process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell |
crossing over | process in which homologous chromosomes exchange portions of their chromatids during meiosis |
recombination | exchange of genes between chromosomes |
DNA | genetic material that organisms inherit from their parents |
mutation | change in the genetic material of a cell |
mitosis | part of eukaryotic cell division during which the cell nucleus divides |
daughter cells | one of the two or more cells formed in the division of a parent cell |
asexual reproduction | process of reproduction involving a single parent that results in offspring that are genetically identical to the parent |
sexual reproduction | type of reproduction in which cells from two parents unite to form the first cell of a new organism |
cell cycle | series of events in which a cell grows, prepares for division, and divides to form 2 daughter cells |
genetic variation | variation in alleles and genes |
chromosome | threadlike structure of DNA and protein that contains genetic information |
