Leeches, ticks, mosquitoes, lampreys, and vampire bats all suck blood. would they form a monophyletic group of close relatives with a recent common ancestor in a phylogenetic tree?

Answer;

No, they would not form a monophyletic group of close relatives with a recent common ancestor.

Explanation;

-This is because their similarities are due to convergent evolution (adaptation to the bloodsucking lifestyle); phylogenetic analysis is based on homologous features, not analogous features.

-Convergent evolution is the process by which unrelated or distantly related organisms evolve similar body forms, coloration, organs, and adaptations. Phylogenetic analysis is based on homologous features, which the above organisms lacks. Homologous traits are those traits that are shared by two or more different species that share a common ancestor.

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
