Question

According to the Chromosomal Theory of Inheritance, what is the source of one chromosome in each homologous pair of diploid organisms?

Options

• Both from the mother

• One from the mother and one from the father

• Both from the father

• One from a previous cell division

Answer 1

Postulate 2 establishes that chromosomes (and genes) occur in pairs in diploid organisms, with one chromosome of each pair coming from the mother and one from the father. This principle forms the basis of allele pairs in diploid organisms and explains biparental inheritance of genetic traits.
