Unit 3 list 3 DNA and hereditary Flashcards
(27 cards)
Cellular division
Single cells split to make daughter cells
Egg cell
A female reproductive cell
Epigenetic
How the environment influences our genes
Fertilization
Combining male sperm with female egg
Genome
Haploid set of chromosomes
Inherited traits
A genetically determined characteristic
Multicellular organism
An organism with multiple cells
Sexual reproduction
Production of new organisms by the combination of genetic information from two different sexes
Sperm cell
A male reproductive cell
Autosomal
A non sex chromosome
Complete dominance
Where the dominant allele masks the recessive one
Dihybrid cross
Breeding experiment of identical hybrids for two traits
F1 (first filial)
The first file generation seeds
F2 (second filial)
Series of crosses with two specific parents
Genotype
The genetic makeup of an organism
Genotypic ratio
Amount of times a genotype would appear in an offspring after test cross
Hardy-Weinberg Equilibrium
Genetic variation that stays constant in a population
Hardy-Weinberg
The genetic variation in a population
Incomplete dominance
When alleles do not cover the recessive one
Monohybrid cross
A breeding experiment where parents differ in one genetically determined trait
P (parental) generation
The first set of parents crossed
Phenotype
A individuals observable traits
Phenotypic ratio
A ratio comparing out comes of an organism based on physical appearance
Polygenic inheritance
Inheritance of a trait governed by one or more genes
