Chromosomes with different lengths, different centromere positions, and different staining patterns on a karyotype.Group of answer choicesnonhomologous chromosomeshomologous chromosomes
Solution
The chromosomes described - those with different lengths, different centromere positions, and different staining patterns on a karyotype - are nonhomologous chromosomes.
Homologous chromosomes are a pair of chromosomes, one from each parent, that have the same length, centromere position, and staining pattern. They carry the same genes in the same order, but the alleles for each trait may be different.
Nonhomologous chromosomes, on the other hand, do not pair during meiosis and do not have the same gene sequence. They can have different lengths, different centromere positions, and different staining patterns, as described in the question.
