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. |
