Yes, theoretically possible, but so exceedingly rare that it has not been reported as far as I know…
Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
2 different alelles - heterozygous Same alelles - homozygous
Chromosomes that appear identical are called homologous chromosomes. They carry the same genes in the same order but may have different versions of those genes (alleles). Homologous chromosomes are inherited, one from each parent, and are important for genetic variation and the process of meiosis.
Homologous chromosomes do not have identical DNA sequences; while they carry the same genes, the alleles (variations of those genes) can differ between the chromosomes. Additionally, homologous chromosomes can vary in size, shape, and genetic content due to the presence of different alleles and possible structural differences. Thus, the key characteristic that is not true for homologous chromosomes is that they are not identical in sequence.
Homologous chromosomes
No they are not identical
no, we have short and long pairs of chromosomes,They are similar to mother cells.But they are different from each other
fraternal twins have two different chromosomes

The chromosomes in your skin are identical to the chromosomes every other one of your body's cells with the exception of gametes. The chromosomes of your sperm and eggs have only half of the chromosomes that are found in your skin cells.

yes because all they are, are one chromosome divided directly in half in to 2 identical chromosomes. :-)

A pair of genes that are identical are called alleles. Alleles are different forms of the same gene that occupy the same position on homologous chromosomes.
