Heredity

• a model that is used to show the probability of all possible genotypes and phenotypes of offspring

• the passing of traits from parents to offspring

• a genotype in which the two alleles of a gene are different

• an inheritance pattern in which an offspring’s phenotype is a combination of the parent’s phenotype

Phenotype

• genetic makeup of an individual
• a specific location on a chromosome
• physical characteristics of an individual
• the fundamental unit of heredity

Which is homozygous recessive?

• BB
• Bb
• bb

Selective Breeding

• a model that shows genetic traits that were inherited by members of a family

• the selection of breeding of organisms for desired traits

• when the last individual of a species dies

• a branch of biology that studies why many species are in trouble and what can be done to save them
