Explanation:
although independent variables can stand alone dependent variables rely on the independent variables therefore when you change the independent variables the dependent variables can no longer depend on the independent variables.
Answer:
Species could go extinct when their environment changed if they could not adapt to the change.
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!!!
