Question

On basis of independent assortment and physical basis of inheritance, what actually assorts independently?

• A. Sister chromatids
• B. Homologous chromosomes
• C. Heterologous chromosomes
• D. Different genes on same chromosome

Answer 1

The correct option is B Homologous chromosomes

According to Mendel's second law, which is also called as law of independent assortment - during gamete formation the segregation of the alleles of one allelic pair is independent of the segregation of the alleles of one allelic pair. Cytological studies have revealed that only those allelomorphs assort independently during meiosis which are located in different homologous pairs of chromosomes.

So, the correct answer is 'Homologous chromosomes'
