1. The forelimbs of the human, cat, whale, and bat contain homologous bones. The upper part has one bone, the lower part has two parallel bones, and the lowest part has a
number of small bones that can slide past one another. The butterfly wing contains no
bones.
A. Compare the structure and FUNCTION of the cat forelimb with the bat forelimb. Analyze
and evaluate the evidence for or against a common ancestor among these animals.
Indicate whether these are homologous or analogous structures.

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).
