Lecture 3 Flashcards
the hardy-weinburg eq
it is a the frequency of A and B
q + p =
1
what kind of model is mating seen as
it is random and seen as collisions
conditions for HWE
random mating
infinite pop size
no migration, mutation, naturel selection
diploid
discrete generation
men/women and allele frequencies are identical
how to find DF
DF is genotype # - allele #
What is the reality in forensics databases
they are very few people in the population
if mating is not random then it is
it is assortive (inbreeding)
what does inbreeding cause
it causes an increase in homozygote
postiive assorment
like genotypes mating
negative assortive
unlike genotypes mating
what is fixation index (F)
measures heterozygosity increase and decrease
the same alleles means
positive F
different alleles
negative F
what is the assumption about the second allele
it is independent and has no correlation (random)
