asexual and sexual reproductiuon

what is sexual reproduction

fusion of different type of male + female gametes

advantage of asexual reproduction

easier - quick

no need to find a sexual partner

uses mitosis (cell divides into 2)

disadvantage of asexual reproduction

no genetic variation

they are clones (genes and chromosomes are identical)

if there’s a disease, they will all die as they are genetically identical

disadvantage of sexual reproduction

finding a partner

meiosis —> happens in sperm and ovaries to make gametes (46→23 chromosomes)

advantage of sexual reproduction

more genetic variation

if a disease comes, they will have more chances of survival

describe the differences between asexual and sexual reproduction

asexual reproduction:

no fertilisation

no genetic variation

no gametes formed

only one parent required
