The character which appears physically in an animal is __________?
Correct answer: B. Phenotype
- A. Genotype
- B. Phenotype
- C. Heterotype
- D. Morphozygous
Explanation
The phenotype is the observable physical or physiological expression of an organism's genetic makeup, such as height, eye colour, or blood group. The genotype is the allele combination underlying that expression and may not be directly visible. Students may choose genotype because it determines the character, but determination is different from physical appearance.

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
