Consider all three processes -- mitosis, meiosis and fertilization. Which ones produce genetic variation?
Consider all three processes -- mitosis, meiosis and fertilization. Which ones produce genetic variation?
Homework Answers
The correct option is meiosis.
Genetic variation is produced and increased by the process of meiosis. The process of meiosis results in genetic variation by shuffling of maternal and paternal chromosomes and crossing over.

Processes that determine heredity and contribute to genetic variation Meiosis guarantees that in a sexual life cycle, offspring will inherit one complete set of chromosomes (and their associated genes and traits) from each parent. The transmission of traits from parents to offspring is called heredity. Another important aspect of meiosis and the sexual life cycle is the role these processes play in contributing to genetic variation. Although offspring always resemble their parents, they are genetically different from both of their...

all these questions have more than one correct answers 1) Meiosis & mitosis have similarities as well as differences. Which of the following represent similarities? a) Both increases genetic variation b) Both change in chromosomes number in daughter cells c) Both only occur in eukaryotes D) DNA replication must occur prior to both e) Both make use of a spindle to separate chromatids 2) Meiosis is a special form of cell division. Select any of the following that applies to...

Why must all sexually reproducing organisms have both mitosis and meiosis in their life cycles? In other words, what is the purpose of meiosis AND what is the purpose of mitosis and how are they different? Without sexual reproduction evolution would be extremely slow. Why ? And what stage and steps in meiosis are so important to the genetic variation within a species?

Which of the following statements about mitosis and meiosis are TRUE? (check all that apply) Mitosis consists of a single nuclear division, whereas meiosis consists of two nuclear divisions. Mitosis produces genetically identical cells, whereas meiosis produces genetically variable cells. The number of chromosomes in the newly formed cells is the same as in the original cell in both mitosis and meiosis. DNA replication occurs prior to mitosis and meiosis.
