  1. Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (such as a sperm or egg cell) with a single set of chromosomes (haploid) combines with another to produce a zygote that develops into an organism composed of cells with two sets of chromosomes (diploid).

    What is sexual reproduction?
    Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (such as a sperm or egg cell) with a single set of chromosomes ( haploid) combines with another to produce a zygote that develops into an organism composed of cells with two sets of chromosomes ( diploid ).

    Is sexual reproduction an adaptive feature?
    Sexual reproduction is an adaptive feature which is common to almost all multi-cellular organisms (and also some single-cellular organisms) with many being incapable of reproducing asexually.
    en.wikipedia.org/wiki/Evolution_of_sexual_reproduction
    How did sexual reproduction change the process of evolution?
    Prior to the advent of sexual reproduction, the adaptation process whereby genes would change from one generation to the next ( genetic mutation) happened very slowly and randomly. Sex evolved as an extremely efficient mechanism for producing variation, and this had the major advantage of enabling organisms to adapt to changing environments.

    Do both sexes reproduce at the end of the life cycle?
    Both sexes reproduce during the haploid and diploid stages of their life cycle and have a 100% chance of passing their genes into their offspring. Some species avoid the cost of 50% of sexual reproduction, although they have "sex" (in the sense of genetic recombination ).

    Jump to navigation Jump to search. Sexual reproduction is how most animals and plants reproduce. Some protists and fungi also reproduce this way. Organisms that reproduce sexually have two different sexes: male and female . In sexual reproduction, offspring are produced when sperms fertilise eggs from the female.
