Meiosis V Mitosis
| Term | Definition |
|---|---|
| Allele | one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome. |
| fertilization | the action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote. |
| Gametes | -a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote. |
| gene | a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring. |
| genetics | the study of heredity and the variation of inherited characteristics. |
| Genotype | the genetic constitution of an individual organism. |
| Heterozygous | refers to a pair of genes where one is dominant and one is recessive |
| Homologous | similar in position, structure, and evolutionary origin but not necessarily in function. |
| chromosome | a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes. |
| Homozygous | you've got a pair of matching alleles, which are the two genes that control a particular trait. |
| hybrid | of mixed character; composed of mixed parts. |
| distributed | among cells |
| meiosis | a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. |
| phenotype | the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment. |
| Probability | how likely it is to get characterics from your parent. |
| Punnett square | a diagram that is used to predict an outcome of a particular cross or breeding experiment. |
| zygote | a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum. |
