The differences in the genetic variations in the yup locus of Mimulus cardinalis ( M. cardinalis ) and Mimulus lewisii (M. lewisii ) plant species affecting the visitation by the hummingbirds and bees. Given: The variation at a single locus called the yup caused color differences in the two species, which was found by the researchers. The gene of M. cardinalis allele C is recessive, whereas the allele L of the M. lewisii is dominant. The genotypes CC were found to be red, and the genotypes LC and LL were found to be light pink. The preference of the bees and hummingbirds were recorded. The graphs below show the visitation rates of the bees and hummingbirds. Introduction: Flower shows a variety of morphology having different color, structure, and texture. The morphology of flowers is decided by their genetic trait. Pollination plays an important role in the life cycle of the plant. It helps in fertilization of flowers. Pollination is carried out with the help of different insects, birds, and animals.

Question

The ratio of nonsynonymous differences pernonsynonymous site, dN, to synonymous differences per synonymous site, dS, can be usedto test for positive selection Imagine that in a duplicate pair of loci, oneparalog is evolving neutrally while the other isevolving under strong positive selection.

. Consider the genotypes of two lines of chickens: thepure-line mottled Honduran is i/i ; D/D ; M/M ; W/W, andthe pure-line leghorn is I/I ; d/d ; m/m ; w/w, whereI = white feathers, i = colored feathersD = duplex comb, d = simplex combM = bearded, m = beardlessW = white skin, w = yellow skinThese four genes assort independently. Starting withthese two pure lines, what is the fastest and mostconvenient way of generating a pure line that has coloredfeathers, has a simplex comb, is beardless, and has yellowskin? Make sure that you showa. the breeding pedigree.b. the genotype of each animal represented.c. how many eggs to hatch in each cross, and why thisnumber.d. why your scheme is the fastest and the mostconvenient

In a population of wild squirrels, most of them have gray fur, butan occasional squirrel is completely white. If we let P and p represent dominant and recessive alleles, respectively, of a genethat encodes an enzyme necessary for pigment formation,which of the following statements do you think is most likely tobe correct?a. The white squirrels are pp, and the p allele is a loss-offunction allele.b. The gray squirrels are pp, and the p allele is a loss-offunction allele.c. The white squirrels are PP, and the P allele is a loss-offunction allele.d. The gray squirrels are PP, and the P allele is a loss-offunction allel
