A dihybrid test-cross, involving parents with the phased genotypes of Ab/aB and ab/ab, produced 100 offspring. Assuming that genes A and B are located on one or more autosomes and 10 of the offspring inherited the aabb genotype. What is the most likely genetic distance between genes A and B? Answer= 20cM Please Explain Why! Thanks

genes A and B are 20 map units apart. If you cross Ab/aB xab/ab, how many each progeny type would you expect if total progeny was 1000. a. AaBb(AB/ab) b. Aabb ( Ab/ab) c. aaBb(aB/ab) d. aabb(ab/ab) is b and c the parental ? would that mean that b and c are 20 ? Thanks

1. You carry out a dihybrid cross in petunias. You are unaware of the linkage relationship between the genes DBL and CAS. One parent has single flowers (dbl) and has and upright growth habit (cas) while the other parent is wildtype, having double flowers (DBL) and a cascading growth habit (CAS). You cross the two parents to produce a wild-type F1 and then carry out a testcross. (a) Write the genotypes, using the correct notation, of the two individuals used...

A dihybrid cross is carried out on two plants with violet flowers. The progeny are as follows: 191 violet flower plants 54 pink flower plants 81 white flower plants The extention/modification that best accounts for these data is [A]. Be specific! The heterozygote genotype is AaBb (loci are on different chromosomes), and the A locus is associated with the violet and pink phenotypes. Given this information, state the possible genotypes...

. . . Activity E. Predicting the outcome of a dihybrid cross The resulting phenotypic ratios in the F2 generation of a dihybrid cross (2 traits) can be quite different than those observed from a monohybrid cross. But the process is essentially the same. First you list all possible gametes each parent and subsequent parents can produce. Second, you then assign the gamete possibilities to the Punnett square and fill it in. Finally you count the progeny and determine the...

Using the expected number of progeny that are double crossovers based on this data, and given an interference value of –0.18, how may double cross-over progeny should be observed?

I'm having trouble understanding this problem. The most frequent
F2 progeny seem to have had crossover to me because the parents are
Aa Bb x aa bb but the progeny are Aa bb and aa Bb. I thought
parental progeny would have the same genotype as the parents. Can
you please explain how the most frequent progeny don't have
crossover? Thank you
