Look at the F1 generation in Figure 21.7 in both your book and the powerpoint lecture. Explain how a Kit+Kit+ mouse in the F1 generation can have white feet and tail. Are both of the Kit+ alleles silenced in the F1 generation Kit+Kit+ mice?

Shown in the pictures below are the degrees of dominance in the inheritance of flower color in some plants. *Based on the phenotypes (or maybe genotype), differentiate between complete dominance, incomplete dominance, and codominance. Be able to discuss the difference briefly but concisely. You may also refer to the definition.

Give typed full explanation  The Genes you are examining exhibit a continuous pattern of variation. For these Genes, a Dominant Allele represents a 1 foot increase in overall height. If you cross the following individuals, AaBb and AaBb, what percentage of the offspring will be 7 feet tall. Assume an individual with no Dominant Alleles (aabb) is 4 feet tall. Report your answer as a percentage i.e., 22.1%.

Gene interaction and Epistasis Dog ears may either be drooping or erect. In terms of their barking, some always bark, others sometimes bark, and still other are non-barking. Two dogs from the same species but of different phenotypes were used in the cross: P1 phenotype              drooping ears &  Non-barking         X            erect ears &   sometimes bark P1 genotype                              AABB                                                                    aabb F1 phenotype                                              100% drooping ears & Non-barking F1 genotype                                                                        AaBb   Mating the male and female from F1 produced:  F2 phenotypes                                           F2 genotypes 4 drooping ears & non-barking                     A_B_       1 drooping ears & always bark                     A_bb 2 erect ears & sometimes bark                    aaB_  aabb    Using the same…

Please explain how you do this question step by step I am very confused! thank you:) You have three independent mutant alleles in the Drosophila gene no-antenna: nan1, nan2 and nan3.  You determine the phenotype of Drosophila that are heterozygous for the three alleles (heterozygous for a wild-type allele and a mutant allele), and that are homozygous for the three mutant alleles.  The antenna is composed of three segments that are followed at the distal end by a feathery arista (that is the antenna is composed of three segments and an arista). Allele nan1 nan2 nan3 heterozygous Wild-type No arista Wild-type homozygous No arista No antenna No antenna nan1 is a __x__ allele, nan2 is a __y__ allele, and nan3 is a __z__ allele.     X Y Z A Dominant negative Null Hypomorphic B Null Dominant negative Hypomorphic C Null Hypomorphic Dominant negative D Hypomorphic Dominant negative Null E Dominant negative Hypomorphic Null Referencing the table above, select the…

. The human IGF2 gene is autosomal and maternallyimprinted. Copies of the gene received from themother are not expressed, but copies received fromthe father are expressed. You have found two allelesof this gene that encode two different forms of theIGF2 protein distinguishable by gel electrophoresis.One allele encodes a 60K (Kilodalton) blood protein;the other allele encodes a 50K blood protein. In ananalysis of blood proteins from a couple named Billand Joan, you find only the 60K protein in Joan’sblood and only the 50K protein in Bill’s blood. Youthen look at their children: Jill is producing only the50K protein, while Bill Jr. is producing only the 60Kprotein.a. With these data alone, what can you say about theIGF2 genotype of Bill Sr. and Joan?b. Bill Jr. and a woman named Sara have two children, Pat and Tim. Pat produces only the 60K protein and Tim produces only the 50K protein. Withthe accumulated data, what can you now say aboutthe genotypes of Joan and Bill Sr.?

You are interested in studying position effect variegation in Drosophila using the chromosome depicted below: Deactivation of the w+ gene gives a white eye phenotype and deactivation of the rst+ gene gives a rough eye phenotype; the normal phenotypes are red and smooth. Because the rst+ and w+ genes have now been placed close to a heterochromatic domain, some sections (or sectors) of the eye display mutant phenotypes due to gene deactivation while others display the normal, wild type phenotype. Which phenotype would you not expect to see rst w Inverted X chromosome white smooth eye sectors white rough eye sectors red smooth eye sectors red rough eye sectors
