CC DD and cc dd individuals were crossed to each other, and the F1 generation was backcrossed to the cc dd parent. 903 Cc Dd, 897 cc dd, 98 Cc dd, and 102 cc Dd offspring resulted. 1. How far apart are the c and d loci? 2. What progeny and in what proportions would you expect to result from testcrossing the F1 generation from a CC dd x cc DD cross to cc dd?
CCDD and ccdd individuals were crossed to each other, and the F1generation was backcrossed to ccdd parent. 903 CcDd, 897 ccdd, 98Ccdd, and 102 ccDd offspringresulted.a) How far apart are the c and d loci?b) What progeny would you expect to result from backcrossing the F1geeration from a CCdd * ccDD cross to ccdd?
7. If the Fz generation were produced, what proportion of the offspring would you expect to produce 14 pound fruits? a. 1/16 b. 128/256 c. 56/256 d. 47/128 e. 1/256 8. When two 12 pound F2 trees were crossed they produced offspring which all produced 12 pound fruit. However, when these offspring were crossed randomly, the fruit produced weighted from 4 to 20 pounds. What can you say about the possible genotypes of the original F2 trees? 65 AJ. Jones...

5. Quantitative trait loci(QTL) are: The loci that contribute all of the variation in a continuous trait The loci that contribute all of the genetic variation in a continuous trait The loci that contribute the broad-sense heritability in a continuous trait The loci that contribute the narrow-sense heritability in a continuous trait 6. We looked at a study where Drosophila flies were selected for phototaxis (either attracted to or repelled by light). This experiment measures how much genetic variation existed...
