Genetics Flashcards
(27 cards)
Father of genetics
studied pea plants
experiment published in 1865
gregor mendal
a sexual reproduction happens by what
binary fission
how does yeast divide
budding
what can multi-cellular do
regenerate and propagation
single cell asexual, how do they reproduce
binary fission
budding
DNA packing
what does it do
DNA is packed into chromosomes
DNA coils around histones
histones coil to form supercoil
passing of traits from generation to generation
heredity
human race: two arms walks on two legs,
species traits
brown hair, blu eyes
individual traits
TT dominate or recessive
Dominate
in asexaul or sexual reproduction do allels come in pairs?
sexual
alike genetic pairs also called purebread
mixture of two alleles
ex: TT
homozygous
principle of segregation:
each individual has two allels for a gene
the alleles of each gene segregation during meiosis
when genes separate and are placed within the gametes
distribution is random
law of independent assortment
a chart grid used to determine the probability of an event happening
punnett squares
monohybrid
1 trait
dihybrid
2 trit
trihybrid
3 traits
all possible allele combinations of the offspring produce
genotype
physical characteristics of each genotype
phenotype
Ff is heterozygous or homozygous
heterozygous
FF is heterozygous or homozygous
homozygous
set of alleles for a given trait
a genotype
an alternative form a gene
Allele
