Which results in genetic variation in body cells?(1 point)
Responses

meiosis
meiosis

mutations caused by environmental factors
mutations caused by environmental factors

crossing over
crossing over

errors during gamete DNA replication

Answer 1

The option that results in genetic variation in body cells is **mutations caused by environmental factors**. While meiosis and crossing over are processes that contribute to genetic variation in gametes (sex cells), mutations can introduce changes in the DNA of body cells (somatic cells), leading to variation. Errors during gamete DNA replication primarily affect genetic variation in the gametes themselves, not in somatic cells.
