Allopatric speciation occurs without gene flow rather it is due to the geographical isolation of populations of the initially same species True False Question 7 2 points Listen In lake Tanganyaka there is a population of fishes with 2 alleles B and b for the gene coding for the color of the dorsal fin of the fish B is dominant over b The dominant phenotype for the dorsal fin is black whereas the recessive phenotype is blue Following the Hardy Weinberg equation and knowing that the population includes 100 members 25 fishes with a blue fin 75 with a black fin including 20 of heterozygous determine the provide the value of n and that of a
the phenotype of the majority of the individuals in this population Question 5 1 point Listen Evolution can be defined as the variations in the alleles frequency of a population over time True False Question 6 1 point 4 Listen Allopatric speciation occurs without gene flow rather it is due to the geographical isolation of populations of the initially same species True False
