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
