SOLVED: A hybrid allotetraploid species (4n = 60) wasbackcrossed to one of the suspected parents (2n = 30).When the F1 underwent meiosis, the prophase chromosomeconfiguration was examined. If the guess about the suspected parentwas correct, what would the chromosome configuration look like? theanswer is 15 pairs and 15 singles. Could you please explainwhy?

SOLVED:The cross E / E ·F / F ×e / e ·f / f is made, and the F1 is then backcrossed with the recessive parent. The progeny genotypes are inferred from the phenotypes. The progeny genotypes, written as the gametic contributions of the heterozygous parent, are in the following proportions: E ·F (2)/(6) E ·f (1)/(6) e ·F (1)/(6) e ·f (2)/(6) Explain these results.

C C D D and c c d d individuals were crossed to each other, and the F1 generation was backcrossed to the c c d d parent. 997 Cc Dd, 999 cc dd, 1 Cc dd, and 3 c c D d offspring resulted. a. How far apart are the c and d loci? b. What progeny and in what frequencies would you expect to result from testcrossing the F1 generation from a C C d d ×c c D D cross to c c d d ? c. In a typical meiosis, how many crossovers occur between genes C and D ? d. Assume that the C and D loci are on the same chromo

The recessive allele s causes Drosophila to have small wings, and the s^ allele causes normal wings. This gene is known to be X linked. If a small-winged male is crossed with a homozygous wild-type female, what ratio of normal to small-winged flies can be expected in each sex in the F1 ? If F1 flies are intercrossed, what F2 progeny ratios are expected? What progeny ratios are predicted if F1 females are backcrossed with their father? | Numerade
