Biology: Chapter 9.2

Chapter 9.2 Vocabulary

Genotype an organism's genetic makeup
Phenotype an organism's appearance
Homozygous when both alleles of a pair are alike
Heterozygous when the two alleles of a pair are different
Probability the likelihood that a specific event will occur
Monohybrid Cross a cross in which only one characteristic is tracked
Punnett Square a diagram biologists use that aid them in predicting the probable distribution of inherited traits in the offspring
Genotypic Ratio the ratio of the genotypes that appear in offspring
Phenotypic Ratio the ratio of the offspring's phenotypes
Testcross in which an individual of unknown genotype is crossed with a homozygous recessive individual; can determine the genotype of any individual whose phenotype expresses the dominant trait
Complete Dominance when one allele was completely dominant over another
Incomplete Dominance when the offspring have a phenotype in between that of the parents; occurs when the phenotype of a heterozygote is intermediate between the phenotypes determined by the dominant and recessive traits
Codominance occurs when both alleles for a gene are expressed in a heterozygous offspring; neither allele is dominant or recessive, nor do the alleles blend in the phenotype
Dihybrid Cross a cross in which two characteristics are tracked
