- (E) Natural Selection:
What would violate the conditions of Hardy Weinberg equilibrium?
Mechanisms of evolution correspond to violations of different Hardy-Weinberg assumptions. They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection.
What happens when a population is not in Hardy Weinberg equilibrium?
When a population is in Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies will stay the same across generations. If the assumptions are not met for a gene, the population may evolve for that gene (the gene’s allele frequencies may change).
What is meant by Hardy Weinberg equilibrium?
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors. For instance, mutations disrupt the equilibrium of allele frequencies by introducing new alleles into a population.
How does inbreeding affect allele frequencies?
Individuals who are related genetically are termed consanguineous, and the offspring of mating between such individuals are said to be inbred. Inbreeding increases the frequency of homozygous genotypes and decreases the frequency of heterozygous genotypes in the population.
What is the most inbred country?
Brazil
Why is inbreeding a bad idea?
This is important as certain congenital defects and genetic diseases, such as cystic fibrosis, are carried by recessive alleles. Inbreeding stacks the odds of being born with such conditions against you. Charles suffered from numerous disabilities and congenital defects.
Why is inbreeding a problem?
Inbreeding increases the risk of recessive gene disorders Inbreeding also increases the risk of disorders caused by recessive genes. These disorders can lead to calf abnormalities, miscarriages and stillbirths. Animals must have two copies of a recessive gene to have the disorder.
Why does inbreeding lead to homozygosity?
Mating closely related animals on purpose, like brother and sister or father and daughter matings, results in an increased probability that the offspring of the mating will receive the same allele from both parents. This results in increased homozygosity, and thus in inbreeding.
Can incest cause mental health problems?
The incest victims also suffered certain psychiatric disorders more frequently than did the other women. The incest victims most often suffered alcohol dependence, depression, panic attacks and phobias, especially a fear of public places–all potentially disabling and all highly treatable.
