Step by step
Solved in 3 steps
- How is it possible toobtain the probability ofemergence of a givengenotype formed of more thanone pair of different alleleswith independent segregationfrom the knowledge of theparental genotypes?What is the differencebetween dominant allele andrecessive allele?Which is the type of gamete(for a given trait) produced bya dominant homozygousindividual? What is thegenotypical proportion ofthese gametes? What about arecessive homozygousindividual?
- What are some examplesof phenotypical characteristicsthat present two or morevarieties and of phenotypicalfeatures that do not vary? Inrelation to the genescorrespondent to thosecharacteristics that varyamong individuals what canbe expected about theiralleles?Scurs is an example of a sex-influenced traitin cattle that is dominant in males and recessive in females.A male and a female, neither of which has scurs, producea male offspring with scurs. What are the genotypes of theparents?For an individual having agenotype formed of twodifferent alleles that conditiondifferent varieties of the samephenotypical trait, upon whatwill the phenotypical featureactually manifested depend?
- A woman who is heterozygous, Bb, has brown eyes; B (brown) isthe dominant allele, and b (blue) is recessive. One of her eyes,however, has a patch of blue color. Give three different explanationsfor how this might have occurred?Let’s suppose a gene exists as a functional wild-type allele and anonfunctional mutant allele. At the organism level (i.e., at the levelof visible traits), the wild-type allele is dominant. In a heterozygote,discuss whether dominance occurs at the cellular or molecularlevel. Discuss examples in which the issue of dominance dependson the level of examination.Huntington disease is a rare fatal, degenerative neurological disease in which individuals start to showsymptoms in their 40s. It is caused by a dominant allele. Joe, a man in his 20s, just learned that his fatherhas Huntington disease.a. What is the probability that Joe will also developthe disease?b. Joe and his new wife have been eager to start afamily. What is the probability that their first childwill eventually develop the disease?
- Two alleles at one locus produce three distinctphenotypes. Two alleles of two genes lead tofive distinct phenotypes. Two alleles of six geneslead to 13 distinct phenotypes. (These statementsassume that the alleles at any one locus arecodominant or incompletely dominant andthat each gene makes an equal contributionto the phenotype.)a. Derive a formula to express this relationship. (Letn equal the number of genes.)b. Each of the most extreme phenotypes for a traitdetermined by two alleles at one locus are foundin a proportion of 1/4 in the F2 generation. If twoalleles of two genes determine the trait, each extreme phenotype will be present in the F2 as 1/16of the population.In common wheat (Triticum aestivum),kernel color varies from red to white andthe genes controlling the color act additively,that is, alleles for each gene are incompletelydominant and each gene contributes equallyto the color. A true-breeding red variety iscrossed to a true-breeding white variety, and1/256 of the F2…How many alleles of genesthat condition X-linked traitsdo female and maleindividuals respectivelypresent?In cats, the allele (B) produces black color but (b) producesyellow color. These alleles are co‐dominant to each other. Aheterozygote produces a tortoise‐shell color. The alleles (B)and (b) are sex‐linked as well. Cross a tortoise‐shell femalewith a yellow male. What percent of their offspring will be yellow? What percent of their offspring will be black? What percent of their offspring will be tortoise shell?
