3. A neutral mutation occurs in a monomorphic population of size 5000, so that in the next generation there are 4999 wild-type individuals and one mutant. The efective population size of this population is 1000. Assuming that no other mutations occur in the near future, what is the probability that this new neutral mutant will fix in the population?

Focus on the evolution of the horn size in the Bighorn sheep population from 1950 to present. What would be evidence that the population evolved in relation to horn size (remember the definition of evolution)? There were more sheep with smaller horns because of mate choice. The genotype frequencies changed but the allele frequencies of H1 and H2 stayed the same. There was a change in allele frequency over time due to the hunting pressure. The population was in Hardy-Weinberg...

n a new generation of offspring, a new neutral mutant appears in a population of size 50. In other words, in this new generation, there are 49 wild-types and 1 new neutral mutant. Using the methods we learned for the Wright-Fisher model, what is the probability that this new mutant mediatelydisappears and is absent in the folowing generation? 7. In a new generation of offspring, a new neutral mutant appears in a population of size 50. In other words, in...

Focus on the evolution of the horn size in the Bighorn sheep population from 1950 to present. Does variation exist for horn size in bighorn sheep? Explain the variation. Yes, variation exists. There are sheep with small, medium and large horns O No, variation does not exist. It is a fixed trait. Yes, variation exists. The sheep can change its horn size to adapt to the environment. Yes, variation exists. The sheep need bigger horns to fight and win mates....

Focus on the evolution of the horn size in the Bighorn sheep population from 1950 to present. What is the origin of the variation in the sheep species? The origin of variation is mating between sheep with all sizes of horns The origin is a response to the selective pressure of hunting pressure making the male sheep have smaller horns The origin is selective pressure of female sheep making the male sheep have bigger horns The origin is a random...
