Homework Answers
The genus Saintpaulia is found in very small portion of east Africa and is a endemic genus and its majority of species being found growing at various elevations throughout the Eastern Arc Mountains of Kenya and Tanzania. The species of this genus produce distinct differences in the seed capsules . So i can argue that these 4 population could be different from one another. It is simply hard to guess the generalisation about the entire genus because there are some commonalities when it comes to the habitats these plants prefer. As we know that genus Saintpaulia grow at a variety of elevations but most of them prefer growing in the shaded forest .Because of their limited geographic distribution the species elevated from one another produce different kind of seed capsule and it produce a huge difference .

A part of the aminoacid sequence in Cytochrome-C protein from 6 different species is given in the table. Rank the organisms from 1 to 5 according to the similarity of the organism to human: based on the similarity between the cytochrome C aminoacid sequences, 1 being the closest to human. It is largely agreed that the greater the number of amino acid (or nucleotide) differences between a given pair of organisms, the further apart they are in evolution. On the...

Could someone check my answers, please? 1. Suppose that a species of fish has split into two populations in a lake: one on the eastern side and one on the western side. How could you determine whether the two populations constitute different species? A. Examine the populations for morphological, color, or other physical differences. B. Examine the populations for different genetic markers and allele frequencies. C. Attempt to breed members from the two populations in captivity. D. Introduce members from...

e) 9; 9 3. In another plant species, the presence and type of hairs on the plant are controlled by epistatic interaction between two independently assorting genes. Gene C determines whether the plant has hairs (dominant) or not (recessive); Rene D determines whether the hairs are straight (dominant) or curly (recessive). In a cross between a straight-haired plant and a curly- haired plant, 1/4 of the offspring have no hairs. 3/8 have straight hairs,...

He wants to test whether a finch-like bird on Island X in the Galapagos archipelago is a different species from the finches found on the other islands in the archipelago. Beak length is used to distinguish finches from other species of birds in the Galapagos archipelago. The mean beak length of the population of finches in the Galapagos is 2 cm; the variance of beak length in...

Under nearly all circumstances, postzygotic reproductive
isolation cannot evolve under the direct action of natural
selection. Instead, postzygotic isolation evolves as a by-product
of other genetic changes as proto-species diverge. In contrast,
natural selection can directly act to enhance prezygotic
reproductive isolation. Consider two species with overlapping
ranges. If hybrids between the species are less fit than pure
species individuals, females that mated with heterospecific males
would be at a selective disadvantage, because their resulting
offspring had low fitness....
