- Given the karyotype shown at right, is this a male or a female? Normal or abnormal? What would the phenotype of this individual be?arrow_forwardIndividuals of genotype AaBb were mated to individuals of genotype aabb. One thousand offspring were counted, with the following results: 474 Aabb, 480 aaBb, 20 AaBb, and 26 aabb. What type of cross is it? Are these loci linked? What are the two parental classes and the two recombinant classes of offspring? What is the percentage of recombination between these two loci? How many map units apart are they?arrow_forwardWhen a single recombination event occurs between a normal chromosome and a chromosome with a paracentric inversion and within the inverted region, what are the expected meiotic products?arrow_forward
- . What is the probability of producing a child that willphenotypically resemble either one of the two parentsin the following four crosses? How many phenotypically different kinds of progeny could potentiallyresult from each of the four crosses?a. Aa Bb Cc Dd × aa bb cc ddb. aa bb cc dd × AA BB CC DDc. Aa Bb Cc Dd × Aa Bb Cc Ddd. aa bb cc dd × aa bb cc ddarrow_forwardWhich of the following statements are true regarding the F2 offspring of a mapping cross for three genes on the same chromosome?arrow_forwardThe A locus and the D locus are so tightly linked that norecombination is ever observed between them. If Ad/Ad is crossed with aD/aD and the F1 is intercrossed,what phenotypes will be seen in the F2 and in whatproportions?arrow_forward
- Is it possible to cross two different pure-breeding yellow zucchini strains and obtain all green progeny? What would be the genotypes of the parents and progeny?arrow_forwardIf genes A and B are linked, how would you figure out what would be the expected percentages of nonrecombinant and recombinant progeny in a test cross of AaBb heterozygotes?arrow_forwardIn your own words, explain why a testcross cannot produce more than 50% recombinant offspring. When a testcross does produce 50% recombinant offspring, what does this result mean?arrow_forward
- If these segregation patterns are equally likely, what is the probability that a gamete produced by the individual who carries the translocatedchromosome will result in a viable offspring with a normal phenotype?arrow_forwardIn a particular organism, the A locus and the D locus are so tightly linked that no crossing over is ever observed between them. If an AADD individual is crossed to an aadd individual, what types of gametes will their double-heterozygote F1 offspring produce and in what proportions? Group of answer choices 25% parental and 75% recombinant gametes 75% parental and 25% recombinant gametes 100% parental and 0% recombinant gametes 50% parental and 50% recombinant gametes 0% parental and 100% recombinant gametesarrow_forwardIn most tests of genetic linkage, the number of double crossovers is less than the number expected due to what effect, which limits the number of crossovers that can occur in a short length of chromosome?arrow_forward
