A class of students mated fruit flies to study the inheritance of traits. The crosses and their results are described below.
Cross 1: A female fruit fly with red eyes mates with a male fruit
fly with brown eyes producing 63 offspring. All 63 offspring in
this first generation have red eyes.
Cross 2: A red-eyed male and a red-eyed female from the
first-generation mate to produce a second generation of flies.
Out of the 98 offspring produced, 74 have red eyes and 24
have brown eyes.
Cross 3: A female fruit fly with black and tan striped body color mates with
a male with black body color. In this first generation, al 56 offspring have
black and tan striped body color.
Cross 4: A black and tan striped male and a black and tan striped female
from the first-generation mate to produce a second generation of flies. Out
of the 103 offspring, 76 have black and tan striped body color and 27 have
black body color.

Expert Solution

Step 1

Introduction :

A single cell divides twice to form four cells during the meiosis process. The amount of genetic material is reduced to half in the daughter cells as compared to the parent cell.

Meiosis plays an important role in ensuring that all organisms created through sexual reproduction have the appropriate amount of chromosomes. Through the mechanism of recombination, meiosis is crucial for bringing about genetic variety. It improves the likelihood of survival.
