Sister chromatids have different alleles although carry same genes on same loci. So if it doesn't happen so, like if there are same alleles on sister chromatids then there is a problem in its formation. i.e., male and female alleles haven't contributed equally ( may be an error during their segregation process ). And obviously it doesn't happen in a real cell so we must understand this point. Because normally whenever it happens there's one half from the male and one half from the female. (i.e. maternal and paternal alleles contribute equally).
I hope you get the answer!!!
A the greater number of progeny that results
Hey there,
The answer is Hydrosphere.
Hope this helps :))

They would have black and white because grey shows up as lavender or blue in a chicken and it can’t be black or white because it says BW that is together so it would have to be black and white
