its usually the size of it and the information that is in the pair
pair 23 is not given a number.
A chromosome pair, as in a pair of Chromosome 15, or a pair of Chromosome 5. Others have said Tetrad - Pls stand-by.
XY
You have pair of X chromosomes in case of females. You have a pair of X and Y chromosomes in case of male.
Chromosome pair 23 in humans is the pair of sex chromosomes. In females, both sex chromosomes are the X sex chromosome, and in human males one sex chromosome is the X and the other is the Y chromosome.

Heterologous chromosomes are those thatdo not belong to the same pair. To give you an example, there are two copies of chromosome 6 and two copies of chromosome 8 in the human genome. If we were to compare one copy of chromosome 6 with one copy of chromosome 8, the pair would be heterolgous
because every chromosome must have a pair to survive
translocation
They have half the number of the somatic (parent) cell. So if a parent cell had 46 chromosomes in its nucleus, then its gamete would have 23(one chromosome from each pair).
Diploid: adj. 1 Double or twofold. 2 Having a homologous pair of chromosomes for each characteristic except sex, the total number of chromosomes being twice that of a gamete.-n 1. a diploid cell. 2. An individual characterized by a diploid chromosome number.It has two copies of each chromosome.
Chromosome number 8. (Gene: RECQL4 gene.)
the answer is TRANSLOCATION.
