11-1, 11-2, 11-3 Flashcards
The transfer of traits from parent to offspring
Heredity
The receiving of traits by the offspring
Inheritance
The original parental generation
P1 Generation
The offspring of the P generation
F1 generation
The offspring of the first filial generation
F2 generation
Sequence of DNA on a chromosome that code for a trait
Gene
A specific characteristic that varies from one individual to another
Trait
Different forms of a gene
Alleles
Genetic makeup of an organism
Genotype
The traits you have because of the genes you have
Phenotype
When an organism has 2 identical alleles for a particular gene
Homozygous
When an organism has 2 different alleles for a particular gene
Heterozygous
Portions of chromatids are exchanged within the tetrad
Crossover
If the dominant allele is present in an organism, the organism will exhibit that trait. In order for the recessive trait to show up, both alleles must be recessive
Dominance and recessiveness
The alleles for a trait are separated during meiosis
Segregation
