The dwarfness in plants of F2 generation is due to:
Correct answer: A. Homozygous recessive alleles
- A. Homozygous recessive alleles
- B. Homozygous dominant alleles
- C. Heterozygous dominant alleles
- D. Heterozygous recessive alleles
Explanation
Dwarf plants appear only when both alleles are recessive (tt), i.e homozygous recessive.

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.
