The correct answer is be sure that your instrument is calibrated properly. If your instrument isn't calibrated, then your data will be inconsistent.
Answer:
Heat can transfer between two objects touching one another. What type of heat transfer is this? What will the temperature of both objects be after these objects remain in contact for a long period of time?
Explanation:
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!!!
