- Doing genetic analysis it is determined that two parents are heterozygous for two separate unlinked recessive traits (i.e., both parents are heterozygous for both loci). Given this genetic information, what is the probability of their having a child which is homozygous recessive for both traits?In the early 1900s, Lucien Cuénot studied the genetic basis of yellow coat color in mice (). He carried out a number of crosses between two yellow mice and obtained what he thought was a 3 : 1 ratio of yellow to gray mice in the progeny. The following table gives Cuénot’s actual results, along with the results of a much larger series of crosses carried out by Castle and Little (W. E. Castle and C. C. Little. 1910. Science 32:868–870). Q.Using a chi-square test, determine whether Cuénot’s results are significantly different from the 3 : 1 ratio that he thought he observed. Are they different from a 2 : 1 ratio?In the early 1900s, Lucien Cuénot studied the genetic basis of yellow coat color in mice ().

- For all seven characters described in the data of Mendel allowed the F2 plants to self-fertilize. He found that whenF2 plants with recessive traits were crossed to each other, theyalways bred true. However, when F2 plants with dominant traitswere crossed, some bred true but others did not. A summary ofMendel’s results is shown to the right When considering the data in this table, keep in mind that theydescribe the characteristics of the F2 generation parents that haddisplayed a dominant phenotype. These data were deduced byanalyzing the outcome of the F3 generation. Based on Mendel’slaws, explain why the ratios were approximately 1:2In the early 1900s, Lucien Cuénot studied the genetic basis of yellow coat color in mice ().

Science 32:868–870). Q.Combine the results of Castle and Little and Cuénot and determine whether they are significantly different from a 3 : 1 ratio and a 2 : 1 ratio.One of Mendel's most significant results was the conclusion that genes determining different characteristics are transmitted independently. In pea plants, Mendel found that round peas (r) are a dominant trait over wrinkled peas (w). Mendel crossbred a group of (rr, yy) peas with a group of ( ww ,gg) peas. In t his notation, rr denotes a pea with two "round" genes and ww denotes a pea with two "wrinkled" genes. The first generation were either (rw,yg) , (rw ,gy) , (wr, yg), or (wr, gy) plants with both hybrid shape and hybrid color. Breeding among the first generation yielded second-generation plants in which genes for each characteristic were equally likely to be either dominant or recessive. What is the probability P [Y] that a second-generation pea plant has yellow seeds? What is the probability P [R] that a second-generation plant has round peas? Are R and Y independent events? How many visibly different kinds of pea plants would Mendel observe in the second generation? What are the…The non-wild-type alleles are k (clipped wings), l (long tail), and m (magical powers). The parental stocks are homozygous doubly recessive flies of genotype k+/k+ · l/l · m/m and homozygous singly recessive flies of genotype k/k · l+/l+ · m+/m+. From this cross, triply heterozygous progeny of genotype k/k+ · l/l+ · m/m+ are obtained, and females of this genotype are testcrossed to triple recessives of genotype k/k · l/l · m/m. The genotypes determining the eight progeny types from this testcross (CROSS C) are shown here with their numbers, out of a total sample of 1,572 flies. What is the correct order of the genes? What number of progeny for each genotype would you predict in the case of independent assortment? What is a non-recombinant genotype? What is a genotype of a single crossover? What is a genotype of a double crossover? What is the longest distance between any of the two dragon alleles above? What is the shortest distance between any of the two dragon alleles above?…
