Document Summary

The collection of genes found in either an individual or a population of individuals. A specific instance of a given gene. Identical or different (heterozygote) aka carries 2 different genes per chromosomes. Carry two copies of every gene (except in the heterogametic sex) Expressed if only one allele is required to generate the trait. Red eyes in fruit flies is dominant (wildtype) Genes provide the basic blueprint for an organism. Cells have a meter long strand of dna. Fruit fly example: bristle formation in drosophila. Nutrition of mother changed coat color of her offspring. A segment of the genome that gives rise to an rna product.
