heredity
traits being passed on from gen to gen
genotype
The alleles an organism has (e.g., Tt).
phenotype
The trait you see (e.g., tall plant).
Law of Segregation:
parent gives one allele during meiosis
Law of Independent Assortment
Genes are passed on independently of each other
incomplete dominance
offspring is a blend of both traits
autosomes
chromosome pairs 1-22
co dominance
both traits appear in phenotype
carrier
contains the gene that can be passed on but isn’t affected by it
linked genes
genes that are close together on the same chromosome and are usually inherited together
Polygenic Traits:
Traits influenced by multiple genes (e.g., skin color, height).
