Eli keeps a worm bin in his basement because the worms need cooler temperatures to survive. He feeds them about one pound of kitchen
scraps each week. One summer the temperatures rose above the optimal temperature for the red worms (º 85°F) and many in his colony
died. However, those that survive continued to reproduce and within six months his colony was thriving again. The following summer,
unusually warm temperatures once again resulted in the basement temperatures rising above 85°F Surprisingly, Eli noticed that only a small
portion of the worm colony died. What is the best explanation for this?

This problem has been solved! see the answeryou are investigating two traits in fruit flies controlled by one gene each. the b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). after crossing rugose black flies with smooth brown flies, you obtain an f1 generation of 100% smooth black flies.what are the dominant alleles? (1 pt)what are the genotypes of the two parent flies to perform a dihybrid test cross? (1 pt)after running a dihybrid test cross, you find 1000 offspring with the following phenotypes: , rugose406black, smooth86brown, rugose94brown, smooth4141000fill in the expected column with the expected number of offspring in each class of phenotypes. (1 pt)what phenotype classes represent the recombinant offspring? (1 pt each)calculate the relative genetic distance between the body color gene and the body sculpting gene (show your work). (1 pt).
