Designer Genes: Inheritance Basics, Mendelian, Peidgrees, Punnet Squares

autosomal

genes transmitted to offspring via non sex-related chromosome

sex-linked

genes transmitted to offspring via sex chromosomes (X or Y)

codominance

both allesl expresses dominantly (red-white flower)

incomplete dominance

neither allele is dominant , mixed phenotype (pink flower)

you are going to get a lot of mendelian and punnet square questions what do you need to do?

practice questions

x-linked recessive

trait appears more in males then females

x-linked dominant

fathers pass on to daughter only

Mitochondial

only mothers can pass it on

what do you need to do to get good a pedigrees?

practice problems

epistatis

a genetic phenomenon where the expression of one gene masks, inhibits, or modifies the phenotypic trait (physical appearance) of another separate gene

polygenic inheritance

multiple genes independently affect a single trait

hybridization

cross of two true-breed varieties

why is codominance more accurate than full dominance

both alleles are always expressed
