Which one of the following is Multiple allelic characters?
Correct answer: B. Blood group of the human being
- A. Colour of flower in pea plant
- B. Blood group of the human being
- C. Shape of seed in pea plant
- D. Length of stem in pea plant
Explanation
Multiple alleles are the alternative forms of the same gene so they influence the same trait. An excellent example of multiple allele inheritance is human blood type. Blood type exists as four possible phenotypes: A, B, AB, & O. There are 3 alleles for the gene that determines blood type.

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.
