Pick up the dominant one among the following traits of Pisum sativum:
Correct answer: D. Round shaped seed
- A. Yellow pod
- B. Constricted pod
- C. Green colored seed
- D. Round shaped seed
Explanation
Mendel identified several traits in pea plants, Pisum sativum, and categorized them as dominant or recessive. Among the given options, the round shaped seed is a dominant trait. This was one of the key findings from Mendel's experiments on heredity. In contrast, yellow pod color, constricted pod shape, and green seed color are all recessive traits, which means they only appear when both alleles are recessive. Hence, these options are incorrect.

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.
