mitosis, meiosis, genetics, dihybrid crosses, morgan, sutton and boveri, curt stern, exceptions to mendel, mutations, human disorders

mendel

father of genetics

incomplete dominance

blending

test cross

used to determine the genotype of a dominant phenotype

sutton and boveri

chromosome theory

chromosome theory

alleles are on chromosomes

morgan

sex linked traits

karyotype

picture of the chromosomes

autosomes

non-sex chromosomes

xx, xy

sex chromosomes

curt stern

crossing over

crossing over

equal exchange of genetic material

chromosome mapping

locating the position of alleles on chromosomes using crossing over information

human genome project

mapping of human genome

linkage group

all the alleles on the same chromosomes

polygenic

more than one set of alleles for a trait

multiple allele system

more than two alleles for a trait in the population

pleiotropy

one allele that codes for two traits

epistasis

one set of alleles that effects the expressions of another set

mutations

errors in the genetic code

mutagens

causes mutations

point mutation

change one base

base deletion

the loss of one base

base insertion

the addition of a base

translocation

loss or gain of a piece of chromosomes

monosomy

loss of a chromosome

trisomy

one extra chromosome

polyploidy

extra set of chromosomes

nondisjunction

unequal separation during meiosis

sex influenced traits

expression of allele determined by the gender
