Inheritance (AP BIO)

Question	Answer
Dominance	(type of inheritance) dominant trait is exhibited ex. tongue roll
Incomplete Dominance	(type of inheritance) 3rd phenotype is expressed from the heterozygous condition ex. red flower + white flower crossed to produce pink flower
Codominance	(type of inheritance) both alleles are dominant + expressed ex. red cow + white cow crossed to produce roan cow
Polygenic	(type of inheritance) multiple allelic pairs are involved to determine phenotype ex. dihybrid cross with the hair type allele (curly/str8), and the hair color allele (blond/brown)
Linked Genes	genes that are located on the same chromosome only separated by crossing over
Sex Linked Genes	genes located on the x/y chromosomes ex. hemophelia, colorblindness (on x chromosome)
Epistasis	expression of one gene is affected by another gene ex. pigment gene needed to express any skin, hair, eye, color genes ---> IF NO PIGMENT: ALBINO
Pleitropy	one gene may cause multiple effects ex. sickle cell anemia --> circulatory probs -> heart probs -> liver probs
