Answer 1

Answer:

D. Acrocentric

An acrocentric chromosome has its centromere near one end of the chromosome, forming a short p arm and a long q arm. The Y chromosome is one of the smallest chromosomes in the human genome, with a total of around 60 million base pairs. It contains the SRY gene region, which is responsible for embryonic sex determination. The Y chromosome is also the only chromosome that can be missing without lethal consequences.
