Summary Introduction
Introduction:
Sexual reproduction takes place in most chordates and non-chordates species and involves the joining of two gametes.
The production of new individuals by the joining (or combining) of two haploid reproductive cells (gametes of female and male) is known as sexual reproduction, which further forms zygote.
The word ‘sexual’ comes from the Latin word ‘sexus (from sexualis)’ which means ‘of copulation or generation’. The other word reproduction comes from the Latin word ‘reproductio’ which means ‘again production’.
Sexual reproduction is the form of natural selection. For sexual reproduction, both men and women need to find a mate.The reason for the mating choice is still controversial.

Students have asked these similar questions
Which is an advantage of asexual reproduction compared to sexual reproduction?
A. Mutations occur in most offspring.
B. Offspring resemble the parents most of the time.
C. Energy is not wasted in finding a mate.
D. The population growth rate and diversity stays constant
Social aspects of reproduction health raise ethical concerns. Why is this an ethical challenge such as hospitals turning away women in labour because they lack insurance
In your own words explain why sexual reproduction tends to give rise to greater diversity among offspring in fewer generations than a sexual reproduction
