What is a reciprocal cross? Suppose that a gene is found as a wildtype (functional) allele and a recessive mutant (nonfunctional)allele. What would be the expected outcomes of reciprocal crossesif a true-breeding normal individual was crossed to a true-breedingindividual carrying the mutant allele? What would be the results ifthe gene is maternally inherited?
What sex ratio would you expect among the offspring of a cross between a normal male mouse and afemale mouse heterozygous for a recessive X-linkedlethal gene? (b) What would be the expected sex ratioamong the offspring of a cross between a normal henand a rooster heterozygous for a recessive Z-linkedlethal allele?
A man has attached earlobes, whereas his wife has freeearlobes. Their first child, a boy, has attached earlobes.a. If the phenotypic difference is assumed to be due totwo alleles of a single gene, is it possible that the geneis X linked?b. Is it possible to decide if attached earlobes aredominant or recessive?
Drosophila may be monosomic for chromosome 4, yet remain fertile.Contrast the F1 and F2 results of the following crosses involvingthe recessive chromosome 4 trait, bent bristles:(a) monosomic IV, bent bristles * normal bristles;(b) monosomic IV, normal bristles * bent bristles.
In humans, free ear lobes (E) is dominant over attached ear lobes (e), and brown eyes (B) is dominantover blue eyes (b). A man with free ear lobes and brown eyes marries a woman with attached ear lobes andbrown eyes. Of four children, one has free ear lobes and brown eyes, one has free ear lobes and blue eyes,one has attached ear lobes and brown eyes, and one has attached ear lobes and blue eyes. Determine thegenotypes of the parents.
are the gene pairs in non allelic interaaction, recessive epistasis independently segragating?
A cross was made between a white male dog and two different blackfemales. The first female gave birth to eight black pups, and the second female gave birth to four white and three black pups. What arethe likely genotypes of the male parent and the two female parents?Explain whether you are uncertain about any of the genotypes
Explain why the percentage of recombinant offspring in a testcrossis a more accurate measure of map distance when two genes areclose together. When two genes are far apart, is the percentage ofrecombinant offspring an underestimate or overestimate of theactual map distance?
In a fungus with four ascospores, a mutant allele lys-5causes the ascospores bearing that allele to be white,whereas the wild-type allele lys-5+ results in black ascospores. (Ascospores are the spores that constitute thefour products of meiosis.) Draw an ascus from each ofthe following crosses:a. lys-5 × lys-5+b. lys-5 × lys-5c. lys-5+ × lys-5+
Let’s suppose a genetic disease is caused by a mutantallele. If two affected parents produce an unaffected offspring, can themutant allele be recessive?
Show the results of a monohybrid cross for the F1 and F2 generation between P generation of a woman who is homozygous dominant for unattached ear lobe with a man who is homozygous recessive for attached ear lobe. Clearly show the cross indicating parent’s sex, genotype and phenotype for each generation. How many offspring in the F2 generation will have attached or detached earlobe?
In cats, orange coat color is determined by the b allele, and blackcoat color is determined by the B allele. The heterozygous conditionresults in a coat pattern known as tortoiseshell. These genesare X-linked. What kinds of offspring would be expected from across of a black male and a tortoiseshell female? What are thechances of getting a tortoiseshell male?
