| Column-I (Characters) | Column-II (Genotypes) | ||
| A. | Monohybrid cross | p. | T and t |
| B. | Test cross | q. | TT |
| C. | Alleles | r. | Tt \[\times \] Tt |
| D. | Homozygous tall | s. | tt |
| t. | Tt \[\times \] tt |
A) A = r, B = t, C = s, D = c
B) A = t, B = r, C = q, D = s
C) A = r, B = t, C = p, D = q
D) A = r, B = p, C = t, D = q
Correct Answer: C
Solution :
[a]Monohybrid cross is a cross between two organisms of a species which is made to study the inheritance of a single pair of alleles. e.g., \[\text{Tt}\times \text{Tt}\text{.}\] [b] Test cross is a cross between \[{{F}_{1}}\]hybrid and recessive parent e.g., \[\text{Tt}\times \text{Tt}\text{.}\] [c] Alleles are the alternative form of a gene e.g., T and t. [d]Homozygous individual contains identical alleles of a gene or factors e.g., Homozygous tall (TT), homozygous dwarf (tt).
