TermDefinition
Allele One of the possible types of a gene. Most genes have a dominant and recessive one.
Autosome Any chromosome that is not a sex chromosome.
Codominance Is when two genes are evenly shown
Dihydrid An organism that is heterozygous for 2 traits
Dominant Allele It is more influential over the recessive allele
Genotype An organism's unique genetics
Heterozygous having a recessive and dominant allele. Two differents ones
Homozygous “Homo” Having the same alleles
Monohybrid hybrid that is heterozygous for one trait
Multiple Allele There are more than 2 alleles
Phenotype appearance that is the way it is because of the environment and genotype
Punnet Square a machine used to forecast the product of easy genetic crosses
Recessive Allele innate factor shown in phenotype but only when genotype is homozygous
Sex Chromosome chromosome that decides sex so either male XY or female XX
Sex-linked Trait a certain trait that is with the sex chromosome but not to do with sexual stuff
Test Cross crossing of the dominant and recessive phenotype
Apoptosis the cell dies because a lot of cellular events have pushed the cell to dying
Cell Cycle a cycle that has cell growth as well as division
Centriole Is cell organelle. Found in pairs. Can organize spindle fibres during division
Centromere area where sister chromatids bind to each other where fibres attach
Chromatin Holds DNA. Is what chromosomes are made of
Chromosome Hold your genes. See during division
Crossing-Over transfer of genes between homologous chromosome .Makes offspring unique
Cytokinesis splitting of the cell in either meiosis or mitosis
Diploid(2n) double # of chromosomes in gametes
Chromosome Number characteristic # of chromosome in cell in certain species
Gamete sexual reproduction cell that makes zygote
Haploid(n) Chromosome Number haploid number (n) is the # of chromosomes in a gamete
Homologous Chromosomes Chromosomes that pair up for meiosis
Meiosis a type of cell division used for sexual reproduction
Mitosis cell division where daughter has same genetic makeup. Used for growth and repair.
Nondisjunction homologous chromosomes failing to split during meiosis
Somatic Cell Any cell that is not a reproductive cell
Synapsis homologous chromosomes pair in meiosis in prophase 1
