Seventhroot doesn't do bio.
No one knows, everyone is disputing over it and most people are now confused
someone ask a teacher already

I think it would be best not to worry about it. Either way, there's nothing that can be done about the exam. Ruminating over your answers will just put you under stress and take time away from your other study.
I don't get how it would be a clone. And the fact that it was worth quite a few marks and asked you to talk about sexual reproduction and gamete formation kinda suggests to me that you had to talk about genetic variability.

Hello. First post here wow
I said that the offspring would not be a clone because of the genetic variation that would occur in meiosis, such as crossing over which could lead to different pairings of alleles when the ova were fused. Since a clone would need to be genetically identical this variation would result in differences and would mean the offspring isn't actually a clone.
I gave an example saying if the lady was heterozygous for some trait Bb (B (dominant) b (recessive)) then the offspring may have the bb genotype and thus have a different phenotype.

buuttt wat if she was a homozygous then the allells would be the same and would result in a clone, unless a mutation occurs... :/
Just an example really, but considering how many genes there are in the DNA it'd be very unlikely that they were homozygous for every single on of them.
I have to agree with Anthony_wheels though, there's no use stressing over it with other exams still left to come.

It's not obviously wth. How would two eggs make a clone ... gametes are different anyway to ensure an increased gene pool ...
gamete * gamete just means more possibilities duh. I wrote exactly what noctua wrote about.

I said it wasnt a clone because crossing over during meiosis.... IDK anymore

Defiantly not a clone, crossing over and random segregation during meiosis thus the chromosomes would not be identical in the gamete and that means a different genotype of the offspring and thus no clone

Wtf no each of ur gametes is different... You make no sense lad

WTF HOW IS IT A CLONE YALL NEEDA L2 BIOLOGY
when a gamete is formed (WHICH IT WAS BECAUSE THE STIMULUS SAID "TWO OVAS") it has ALREADY UNDERGONE THE PROCESSES OF RANDOM SEGREGATION, MUTATION (IF IT DID OCCUR) AND CROSSING OVER
THIS MEANS THEREFORE THAT IT IS NOT A CLONE AS IT IS DIFFERENT TO THE MOTHER FUCKING MOTHER
and the fertilisation of the egg adds more to the variability of the offspring
therefore it is not a fucking clone
in the exam i wrote that in capital letters (it IS NOT A CLONE) and underlined it and highlighted it.
it's not a fucking clone omfg
soz if you wrote it was
however, if you had good reasoning as to why it COULD be a clone, you COULD get full marks IF your answer was good (because both are probably valid)
BUT, using simple genetic principles IT IS NOT A CLONE

Pretty sure it isn't a clone. During meiosis, the chromatids of the cell cross over and there are many variations like cell differentiation, mutation etc, it wont be a clone. Also when it interacts with a sperm there are 23 chromosomes from the sperm and 23 from the ovum so I'm pretty sure they're not cloned.
