its usually the size of it and the information that is in the pair
The size of the chromosome pair determines its number. The largest chromosome pair is given the number 1, followed by the second-largest pair with the number 2, and so on.
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.
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.
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.
