In a study of mating calls in the gray tree frogs Hyla hrysoscelis and Hyla versicolor, Gerhart (1994)2 reports that in a location in Lousiana the following data on the length of male advertisement calls have been collected:

Sample size Average duration SD of Duration Duration range
Hyla chrysoscelis 43 0.5 0.18 0.36-1.27
Hyla versicolor 12 0.54 0.14 0.36-0.75

The two species cannot be distinguished by external morphology, but H. chrysoscelis are diploids while H. versicolor are tetraploids. The triploid crosses exhibit high mortality in larval stages, and if they attain sexual maturity, they are sterile. Females responding to the mating calls try to avoid mismatches Based on the data summaries provided, test whether the length of call is a discriminatory characteristic? Use α = 0.05.

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).
