Consanguinous matings: Increase heterozygousity Increase homozygousity Decrease
ID: 263404 • Letter: C
Question
Consanguinous matings:
Increase heterozygousity
Increase homozygousity
Decrease homozygousity
Increase genetic variation in large populations
The Hardy-Weinberg Law holds true based on which criteria?
Large populations and random mating
Small populations and inbreeding
Geographic isolation
High migration and mutation rates
Hardy-Weinberg Law establishes that:
Genetic frequencies radically shift from generation to generation.
The most populous genotypes are dominant in expression.
Dominant genotypes always favor "survival of the fittest."
Genetic equilibrium remains constant from generation to generation.
If a dominant allele is in 85% of a population (p= 0.85), what percentage of the population will have the recessive allele according to the HW equation?
0%
15%
85%
100%
CODIS is:
a fifteen-base DNA sequence used in profiling
a type of mutation
a DNA profiling data base used by crime laboratories
a technology used to amplify DNA
A "cold hit" refers to:
a DNA profile made from frozen DNA
identifying a suspect from DNA alone
a technology used to preserve DNA found at crime scenes
using mtDNA to generate a profile
In human populations, inbreeding results in:
a decrease in heterozygosity
increase in homozygosity
both a and b
neither a or b due to HW equilibrium
