Short Answer 4. You identify two recessive mutations in fruit flies, one that results in curly wings (cc) and one that res in an ebony body (ee). You cross two flies that are heterozygous for both traits (CcEe), and find 352 flies progeny in the next generation with the following phenotypes: wild type - 193 wild type wings, ebony body - 69 You believe the curly and ebony alleles assort independently and are not linked. Perform a chi square analysis for this cross to test the null hypothesis.

8-9. White eyes (w) is sex-linked and recessive in Drosophila. Cruved wings(cu) and black body (b) are autosomal recessive alleles on the same chromosome, separated by 20 map units. If one breeds a homozygous white, curved winged female fly to a homozygous black male fly to produce an F1, and inbreeds the F1 males and females, at what frequency is a phenotypically wild-type male expected? (note: male flies do not cross over) A. 0.25 es B.0.05 C.0.10 D. 0.20 E.0.125
1- In garden peas, yellow (Y) seed color is dominant to green (y). Because yellow and green are two different forms of the same gene (seed color), they are alleles. Use a Punnett square to show a cross between two heterozygous pea plants. What are the phenotype(s) of the offspring? What are the genotype(s) of the offspring? 2- In garden peas, yellow (Y) seed color is dominant to green (y). Because yellow and green are two different forms of the same gene (seed color), they are alleles. Use a Punnett square to show a cross between two heterozygous pea plants. What are the phenotype(s) of the offspring? What are the genotype(s) of the offspring? Use the information below to answer questions 3-6 There may be a number of possible alleles for a given gene within a population. In a multiple allele system the dominance relationships between the various alleles must be considered. One of the more familiar examples of a multiple allelic system is that of the human ABO blood group. The gene…
Topic: Penetrance. Petal number is controlled by a single gene in merigonias. The gene has a completely dominant wild type allele F that makes a plant have five petals and a mutant recessive six petal allele(f). However the six petal trait is only 50% penetrant. You do the cross Ff x Ff. What fraction of the progeny do you have the 6 petals? what is the meaning for 50% penetrant.
the progeny i each seehario. Q4. You conducted an experiment similar to Morgan's fruit fly but you used honey bee instead. You are thus following 2 genes, the wing size Long (L) and short (1) and body color Yellow (Y) and black (y). You crossed YyLI x yyll and obtained 4,000 offspring. You counted the offspring classes and found the following distribution as follows: 1200 YyLl individuals 1190 yyll individuals 800 Yyll individuals 810 yyLl individuals a) what is the phenotype of each class of offspring? b) Which classes are of the parental type and which are the recombinant types? c) What is the recombination frequency between both genes? d) What is the map distance in cM and in map units between both genes? When you counted the offspring, you also collected data on a third gene coding for antenna shape. The gene has 2 alleles in the population, bended antenna (B) and straight antenna (b). You found a distance of 13 cM between the gene for antenna shape and that for wing size, and 24…
7-5. In corn a pair of genes determines leaf shape and another pair determines pollen shape. A ragged-leafed plant with round pollen was crossed to a ragged-leafed plant with angular-pollen, and the resultant progeny were classified as follows: Class Phenotypes 186 ragged-leaf round-pollen 11 IV 174 ragged-leaf angular-pollen 57 smooth-leaf round-pollen Total 63/480 smooth-leaf angular-pollen (a) Using alphabetical letters of your choice, designate the genes for the different leaf and pollen characters. (b) On the basis of the symbols given in (a) 1 provide genotypes two parents. (c) (forth)/(nbers) According to your hypothesis what would you have expected for each of the four classes of progeny? (d) After re viewing Chapter 8, use the chi-square method (p. 132) to test your hypothesis and indicate whether you accept or reject it.

1-Gigantism is being traced in a family through a pedigree. Its mode of inheritance is thought to be autosomal recessive. You examine the pedigree and decide that the mode of inheritance is not correct. What is the correct mode of inheritance? 2-Provide 2 pieces of evidence for the mode of inheritance selected for Gigantism. (i.e.- Individual 45 is afflicted and passed it on to all of her offspring, indicating that it is dominant. Or there is a gendered pattern of inheritance seen when Individual 99 passed it on to only his female offspring.)
