Respuesta :
f(M) = 0.7, f(N) = 0.3 are the frequencies of the m and n alleles in this population.
What is the relative fitness of genotype BB What is the relative fitness of genotype BB?
- A relative fitness of 1.0 can occur for more than one genotype. B.
- The relative fitness of genotype BB in a population of chickens used as a sample is 1.0.
- The selection coefficients for genotype Bb and genotype Bb are respectively 0.3 and 0.4.
Which of the following processes tends to increase genetic variation in a population?
- Genetic diversity is typically increased by mutations while being decreased by the other three mechanisms.
- Migration tends to homogenize genetic variation, reducing the genetic diversity between populations, whereas natural selection and genetic drift tend to increase it.
Where are alleles?
- Alleles are matching genes; one from our biological mother, one from our biological father.
- We have two copies of every gene (strings of code that drive some biological function on our chromosomes).
- They can be identical, but they can often have slight differences.
