Question
Chapter 16.4, Problem 1EQ
Summary Introduction
To determine:
The original purpose of Morgan’s experiments with Drosophila.
Introduction:
Morgan's experiment explains the process of linkage and recombination. The linkage phenomenon is defined as the transfer of two closely situated or linked genes to pass on to the next generation. Higher the linkage lesser is the recombination frequency because closely linked genes will always be inherited together.

Mention four reasons why Drosophila was chosen by Morgan for his experiments in genetics.
Cat fur coat color genetics is interesting. Orange fur is dominant (''B'') to black fur (''b'') and piebald, which is white spotting, is dominant (''S'') to non-white-spotted (''s''). Both of those genes are located on the X chromosome. In addition, in cats, somatic cells exhibit X-inactivation randomly, which explains why there are tortoiseshell cats (when heterozygous, have orange and black spots) as well as calico cats (orange and black but also with white spots). An orange and white spotted male is mated with a tortoiseshell female.
State the genotype of the male and the female.

You determine the phenotype of Drosophila that are heterozygous for the three alleles (heterozygous for a wild-type allele and a mutant allele), and that are homozygous for the three mutant alleles. The antenna is composed of three segments that are followed at the distal end by a feathery arista (that is the antenna is composed of three segments and an arista). Allele nan1 nan2 nan3 heterozygous Wild-type No arista Wild-type homozygous No arista No antenna No antenna nan1 is a __x__ allele, nan2 is a __y__ allele, and nan3 is a __z__ allele.
