Chapter 4.2, Problem 38AQP

a.

Summary Introduction

To determine:

Female fly that has miniature wings and sepia eyes in crossed with male with normal wings and homozygous for red eyes, the ${\text{F}}_{\text{1}}$ flies are intercrossed to produce the ${\text{F}}_{\text{2}}$ give the phenotype as well as their expected proportions.

Introduction:

X linked recessive inheritance means, in which mutation occur on the gene X chromosome, which leads to phenotype to be expressed in males, and in female who are homozygous for the gene mutation. Any other chromosome other than sex chromosome is autosomal chromosome, their alleles and traits are recessive and dominant in nature.
