Vocab Flashcards
Epistasis
one gene affects the expression of another gene. (suppressor genes)
Polygenitics
multiple genes affect the expression of a single trait.
complete dominance
dominant and recessive
incomplete dominance
blending of dominant and recessive alleles for the heterozygous (black x white = gray)
co dom
express (black x white = Black and white spots)
linked genes
2 genes must be on the same chromosome (also known as recombinant frequency)
multiple alles
A single gene, has many different allelic variations (each may have different interactions with other alleles) EX: Blood typing
test cross
cross ANYTHING with homozygous recessive to determine the genotype of an unknown
p generation
2 true breeding,
f1 generation
Heterozygous for all offspring
f2 generation
1:2:1 ratio
Frame shift
when letters are changed in the amino acid sequence
recombaint
exchanging of genes that result in different aleeles
Interphase
where a cell is copied and then preped for cell divison
metaphase
this step is before interphase and lines up all of the cells for it to be properly divided
law of segregation
the law that explains how a offspring gets two genetic pairs that helps provide genetic diversity
law of assortment
it determines what traits effect certain traits
