Term | Definition |
DNA- | molecule contains the information that determines the traits that a living thing inherits and needs to live |
Chromosomes- | in an eukaryotic cell, one of the structures in the nucleus that are made up of DNA n protein |
Cell cycle- | Life cycle of a eukaryotic cell |
Interphase- | A period of a cell cycle during which activities such as cell growth and protein synthesis occur without visible signs of cell division |
mitosis- | process of cell division that forms two new nuclei, each of which has the same number of chromosomes |
Cytokinesis- | the division of the cytoplasm of a cell. |
homologous chromosomes- | chromosomes that have the same sequence of genes and the same structure |
Meiosis- | a process in cell division during which the number of chromosomes decreased to half the original number by two divisions of the nucleus which results in the production of sex cells. |
asexual reproduction- | reproduction that does not involve the union of sex cells and in which one parent produces offspring that are genetically identical to the parent |
sexual reproduction- | reproduction in which the sex cells from two parents unite to produce offspring that share traits from both parents. |
fertilization- | the union of a male and female gamete to form a zygote. |
heredity- | the passing of genetic material from parent offspring |
Genes- | one set of instructions for an inherited trait |
Alleles- | one of the alternative forms of a gene that governs a characteristic, such as hair color |
genotype- | the entire genetic makeup of an organism also the combination of genes for one or specific traits |
Phenotype- | an organisms appearance or other detectable characteristics |
Dominant- | in genetics, describes an allele that is fully expressed whenever the allele is present in an individual |
Recessive- | Recessive- |
incomplete dominance - | a condition in which two alleles are expressed such that the phenotype of a heterozygous individual is an intermediate of the phenotypes of the two homozygous parents |
codominance- | a condition in which two alleles are expressed such that the phenotype of a heterozygous individual is a combination of the phenotypes of the two homozygous parents |
punnett square- | a graphic used to predict the results of a genetic cross |
ratio- | a comparison of two numbers using division |
probability- | the likelihood that a possible future event will occur in any given instance of the event |
pedigree- | a diagram that shows the occurrence of a genetic trait in several generations |
