Question

a scientist hypothesizes that a mutation at a single locus is responsible for the pattern of inheritance seen in this pedigree. explain how a mutation in a gene can arise during meiosis

Answer 1

Exposure to chemical or radiation.

Step-by-step explanation:

Mutation in a gene can arise during meiosis due to exposure to chemical or radiation that cause change in the genes. After this change in DNA, the meiosis cell division produces gametes that can be passed to the offspring and contribute to genetic variability of the organism. Meiosis occurs in the sex cells which can be transferred from parents to offspring.
