none of the above

Answer 1

In humans, sex chromosomes are either an X or Y. Females receive 2 X chromosomes and males receive an X and a Y chromosome. The X chromosome is physically larger than the Y chromosome.

Answer 2

Females

Step-by-step explanation:

X and Y are the sex chromosomes in humans. In humans the sex chromosomes are in pair. Out of the total of 23 pairs of chromosomes, one pair is sex chromosome and the other 22 pairs of chromosomes are autosomes. In an individual having two X chromosomes (XX) is a female and an individual having one X chromosome and one Y chromosome (XY) is the male. The X chromosome is similar to a large autosome having a long and a short arm but the Y chromosome has one long arm and a very short second arm. Thus, X chromosome is larger than the Y chromosome.
