Scientific study of heredity Genetics Scientific study of heredity
F1 Generation First filial generation
P Generation Parental generation
recessive Allele that may not be expressed
Independent Assortment Two or more pairs of alleles segregate independently
Probability Likelihood that something will happen
Codominance Both genes in the heterozygous condition are fully expressed—you see both
Homozygous Having identical pair of alleles TT or tt
alleles Different forms of a gene
phenotype Physical appearance
segregation Law that says two factors for a trait segregate into two different gametes
Dominant Allele that is always expressed if present
Monohybrid Focuses on only one trait using a punnett square
Heterozygous Having two different alleles for the same trait Tt
Punnett Square Grid that shows possible outcomes of a cross
Dihybrid Cross Shows two traits in a punnett square
Mutation Change in a gene
Genotype The alleles that make up an organism
Incomplete Dominance Intermediate forms of traits of two parents are displayed
