Genetics
Term | Definition |
---|---|
Heredity | the passing on of physical or mental characteristics genetically from one generation to another. |
Genetics | the study of heredity and the variation of inherited characteristics. |
Phenotype | the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment. |
Genotype | the genetic constitution of an individual organism. |
Homozygous | having two identical alleles of a particular gene or genes |
Heterozygous | having two different alleles of a particular gene or genes. |
Heterozygous Dominant | An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene. |
Heterozygous Recessive | An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene. ... Peop |
Genetic Material | The material used to store genetic information in the nuclei or mitochondria of an organism's cells; either DNA or RNA. |
Sexual Reproduction | the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced |
Asexual Reproduction | Asexual reproduction is reproduction without sex. |
Regeneration | the action or process of regenerating or being regenerated, in particular the formation of new animal or plant tissue. |
Budding | (of a plant) having or developing buds. |
Binary Fission | Binary fission ("division in half") is a kind of asexual reproduction. ... In binary fission, the fully grown parent cell splits into two halves, producing two new cells. |
Mitosis | a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. |
Homozygous Dominant | An organism can be homozygous dominant, if it carries two copies of the same dominant allele |
Homozygous Recessive | homozygous recessive, if it carries two copies of the same recessive allele. |
DNA | deoxyribonucleic acid, a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information. |
Punnet Squares | The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. |
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. |
