Intro to Heredity

__________ is the physical expression of a set of genes for a particular trait.

• Genotype

• Chromosome

• Phenotype

• Gene

Since human cells carry 2 copies of each chromosome (one from each parent), they have 2 versions of each gene; these versions of a gene are called ________ and can be dominant or recessive.

• alleles

• homologous chromosomes

• genome

• gene
