According to Mendelism, which character shows dominance?
Correct answer: D. Green pod colour
- A. Terminal position of flower
- B. Green colour in seed coat
- C. Wrinkled seeds
- D. Green pod colour
Explanation
In Mendel's experiments, the concept of dominance is observed in traits such as seed coat color and pod color. Green pod color is determined by a dominant allele (G), while yellow pod color is determined by a recessive allele (g). Green pod color is an example of a dominant trait according to Mendelian genetics. The other options, such as the terminal position of flowers, do not involve Mendelian inheritance patterns, and the concept of dominance doesn't apply to them.

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.
