Inheritance (AP BIO)
Flashcards do conjunto (8)
- 1Dominance(type of inheritance)
dominant trait is exhibited
ex. tongue roll - 2Incomplete Dominance(type of inheritance)
3rd phenotype is expressed from the heterozygous condition
ex. red flower + white flower crossed to produce pink flower - 3Codominance(type of inheritance)
both alleles are dominant + expressed
ex. red cow + white cow crossed to produce roan cow - 4Polygenic(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) - 5Linked Genesgenes that are located on the same chromosome
*only separated by crossing over* - 6Sex Linked Genesgenes located on the x/y chromosomes
ex. hemophelia, colorblindness (on x chromosome) - 7Epistasisexpression of one gene is affected by another gene
ex. pigment gene needed to express any skin, hair, eye, color genes ---> IF NO PIGMENT: ALBINO - 8Pleitropyone gene may cause multiple effects
ex. sickle cell anemia --> circulatory probs -> heart probs -> liver probs
