A chromosome pair, as in a pair of Chromosome 15, or a pair of Chromosome 5. Others have said Tetrad - Pls stand-by.
sister chromatids (after DNA replication, but before dividing)
The term for the two sets of chromatids formed in the parent cell is "sister chromatids." During the S phase of the cell cycle, each chromosome is replicated, resulting in two identical copies that are connected at a region called the centromere. These sister chromatids are separated during cell division, ensuring that each daughter cell receives an identical set of chromosomes.
A single crossover of homologous chromosomes results in two chromatids that have recombined genetic material from both parents. This means that two of the chromatids will have segments from one homologous chromosome, while the other two will retain the original segments from the other homolog. Therefore, the set of chromatids illustrating this result will show two chromatids with new combinations of alleles and two chromatids with the parental combinations.
is it two chromatids or spindles
The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
