Question

Homologous chromosomes can be defined as :

• A. Chromatids of same chromosome
• B. Same chromosome, same gene, different allele in different order
• C. Same chromosome, different gene, same allele
• D. Same chromosome, same gene, different allele in same order

Answer 1

The correct option is D Same chromosome, same gene, different allele in same order

Homologous chromosomes are the chromosomes which contain alleles for the same type of genes (one from sperm and one from egg) or can be called similar. Homologous chromosomes are similiar but not identical. Each carries the same genes in the same order, but the alleles for each trait may not be the same.
