Mendelian Genetics Flashcards
Meiosis
A cell division where chromosome numbers are reduced by half and the daughter cells are destruct genetically from their parents.
Mitosis
Stage in the cell cycle where 1 thing of DNA is equally distributed between 2 identical daughter cells.
Genetics
Study of patterns in heredity and the variation of organisms.
Cross pollination
Reproduction process in which pollen from one plant is transferred to the stigma of another plant.
Allele
The letters that show the genes from mom or dad. Alternate versions of a trait.
Homozygous
A gene pair where 2 alleles code for the same trait (same: dominant AA recessive aa)
Law of segregation
States that pairs of genes separate in meiosis and each gamete receives a gene from each pair.
Hapliod
Having only one chromosome of each homologous pair. (Half)
Diploid
Cell that has both chromosomes of a homologous pair.
Trait
A characteristic
Dominant
An allele that ranks higher then another allele for the same characteristic.
Genotype
Genetic makeup of an organism.
Heterozygous
A gene pair where two alleles don’t code for the same trait (different Aa)
Law of independent assortment
Law that states pairs of genes separate independently of one another in meiosis.
Gametes
Reproductive cell (sperm, male: ova/egg cells, female)
