Mendel concluded that each organism has two hereditary factors for each trait, now called:
Correct answer: B. Alleles
- A. Chromatids
- B. Alleles
- C. Chromosomes

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.

Statement: Due to a substantial reduction in fares by airline services, a large number of passengers who were traveling by upper classes in trains have switched to airline services. Courses of action: I. The railways should immediately reduce the fare structure of the upper classes substantially to retain its passengers. II. The railways should reduce the capacity of upper classes in all trains to avoid loss.
