Natural selection makes an adaptive trait more common in a population. After many generations, will all individuals in the population have the same adaptive trait?

List the premises of evolution by natural selection. What is the inevitable outcome?Variation; heritability; “struggle”/context; differential survival/reproduction

Which of the following is true about fitness? a) It refers to the physical strength of an individual b) It is determined solely by an individual's genotype c) It is the same thing as survival d) It is the ability of an individual to reproduce and pass on its genes to the next generation

Explain what is required for evolution by natural selection to occur in a population.

A hypothetical population has two alleles for a “B" gene: B1 and B2. In a random sample of 50 diploid zygotes (for a total of 100 alleles), the following genotypes were found: 20 B1B1, 20 B1B2, and 10 B2B2 The above values represent the initial genotype frequencies of zygotes in the population. Let's say that selection acts against the B2 allele, and all 10 individuals with B2B2 genotype die off before reaching maturity (leaving 0 B2B2 individuals). (The number of surviving adults in the population is 40, so the number of alleles is 80). What is the new observed frequency of the homozygous dominant genotype? O A. 0.10 О В. О.70 O C. 0.25 O D.0.50 O E. 0.75
