Unit 1 Genetics

3. genes at more than one gene pair influence a single trait
8. offspring produced by crossing an individual back to a parent
11. alternative version of a gene
12. Mendel's first law, genes are in pairs in somatic cells and the pairs separate when gametes are formed
13. the homozygous and the heterozygous genotype having the same phenotype
14. trait phenotype in which individuals are classified into categories that range from one extreme to another, height, weight.

1. trait phenotype in which individuals can be classified into discerete categories, male vs female, normal vs dwarf etc.
2. the genes an organism has at a particular gene pair or gene pairs
4. groups of individuals that produce offspring with their phenotype when mated
5. in population genetics, having a trait that impacts an inviduals reproductive success
6. having two of the same alleles at a gene pair
7. intermating group of individuals
9. classical: something that is found in our cells that controls traits
10. the allele that is masked or covered up by the dominant allele
