Chapter 10

Genetics Scientific study of heredity
Fertilization Process in sexual reproduction in which male and female reproductive cells join to form a new cell
Trait specific characteristic of an individual
True-Breading having two identical alleles for a particular gene
Hybrid offspring of crosses between parents with different traits
Segregation separation of alleles during gamete formation
Independent Assortment One of Mendel's principles that states that genes for different traits can segregate independently during the formation of gamates
Gameters sex cells
Homozygous same as true breading
Heterozygous same as hybrid
Phenotype Physical characteristics of an organism
Genotype genetic makeup of an organism
Dominant Is the trait that is most likely to show up
Recessive This hides behind the dominant trait
Allele One of a number of different forms of a gene
Incomplete Dominance situation in which one allele is not completely dominant over another allele
Punnet Square diagram that can be used to predict the genotype and phenotype combinations of a genetic cross
Multiple Allele Trait a gene that has more than two alleles
Polygenic Trait trait controlled by two or more genes
X-linked Trait Gene located on a a sex chromosome
Carrier You have the gene for the disease but don't have it
