Question

Which two mapped DNA changes shown in the previous question 19 when crossed would result in progeny that would develop with no eyes?

a. Inversion 1 with Insertion 1
b. Insertion 1 with Deletion 2
c. Deletion 2 with Inversion 1
d. Insertion 1 with Insertion 2
e. Insertion 2 with Deletion 2

Answer 1

Deletion 2 with Inversion 1

Step-by-step explanation:

From the information provided, the correct answer is c. Deletion 2 with Inversion 1. Both deletion and inversion are structural changes that can lead to alterations in gene expression. A deletion involves the loss of DNA segments, while an inversion refers to a flipping and reattaching of DNA segments. When deletion 2 and inversion 1 are crossed, it can cause disruptions in the genes necessary for eye development, resulting in progeny with no eyes.
