Question 1 2 pts Which statement represents a result of natural selection! o the best adapted individuals have lower ness ele frequency in a population does not change Onewalls are added to the population seeded O different phenotypes with a species we favored in different habitats Question 2 2 pts When we say that one individual is more fit has higher fitness than other individuals, we mean that it produces more later than others in the population compete for food...
17.You are a geneticist studying the population genetics of Monarch butterflies. You are particularly interested in one gene for which the species has two alleles: B and b. Upon examining the alleles present in 100 individuals, you find that the B allele is very common, with an allele frequency of .6. Therefore, you calculate that there are a total of _______ b alleles present in the population. Group of answer choices A) 60 B) 80 C) 100 D) 120 E)...

1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?
1b) What is this name...
please only experts answer , this question is really tricky ,
