Cards

Term
cross polination
Definition
have on plant pollinate another
Term
allele
Definition
alternative form of gene
Term
law of segregation
Definition
differing traits in organism result from two genetic elements (alleles)that separate in gamete formation, such that each gamete gets only one of two alleles
Term
homozygous
Definition
two indetical alleles of gene for a given character
Term
heterozygous
Definition
differing alleles for a character
Term
dominant
Definition
used to designate an allele that is expreessed in the heterozygous condition,
Term
recessive
Definition
term used to designate an allele that is not expressed in the heterozygous condition
Term
law of independent assortment
Definition
states that during gamete formation, gene pairs assort independetly of one another
Term
multiple alleles
Definition
when three or more alleles of the same gene exist in a population
Term
polygenic inheritance
Definition
inheritance of a genetic character that is determined by the interaction of multiple genes, with each gene having a small additive effect on the character
Term
how many copies of specific gene found in each situation?
Definition
-G1=2
-prophase=4
-gametes=1
Term
phrophase
Definition
replicates
Term
incompletely dominant alleles
Definition
-one copy gives partial phenotype
-need two copies to get full phenotype
Term
codominant alleles
Definition
both phenotypes show up together
Term
genotype and phenotype
Definition
-just because have genotype doesn't mean have phenotype
-Why? -- X activation, late onset, enviorment
Term
polygenic traits
Definition
many genes produce range of characteristics
