Gregor Mendel
father of genetics
genetically determined variant of a characteristic
height, position, color, appearence, texture
What were traits mendel observed about pea plants.
how did Mendel control breeding and track inheritance of traits
what are the male reproductive parts of a flower?
What are the female reproductive parts of a flower called?
P generation
true breeding parents of the crossing
f1 generation
offspring of p generation, to collect seeds
f2 generation
offspring of seeds produced from original p generation
Law of independent assortment
factors separate independently from one another during formation of gametes
molecular genetics
study of the structure and function of chromosomes and genes
two or more alternative forms of a gene
genetic makeup of an organism
appearence of an organism
Punnet square
used to predict outcome of genetic crosses
monohybrid cross
a cross which one characteristic is tracked
Homozygous recessive
both recessive traits
Homozygous dominant
both dominant traits
split traits both dominant and recessive
complete dominance
happens when Hetero and Homozy. individuals are individuals in phenotype
incomplete dominance
occurs when 2 or more alleles influence phenotype and results in a phenotype intermediate b/w dominant and recessive trait.
occurs when both alleles for gene are expressed in heterozygous offspring
dihybrid crosses
a cross where 2 characteristics are tracked.
