If both the alleles are the same with respect to genes, then they are called?
Correct answer: C. Homozygous
- A. Heterozygous
- B. Unicellular
- C. Homozygous
- D. None of these
Explanation
If both of the two gametes (sex cells) that fuse during fertilization carry the same form of the gene for a specific trait, the organism is said to be 'homozygous' for that trait. 'A' is not an answer because heterozygous refers to having inherited different forms of a particular gene from each parent. 'B' is not the answer because the term unicellular refers to the state of a cell.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
