High-Yield Trend
Questions 9 MCQs
F2 generation in a Mendelian cross showed that both genotypic and phenotypic ratios are same as 1: 2: 1. It represents a case of:
1. Co-dominance
2. Dihybrid crosses
3. Monohybrid crosses with complete dominance
4. Monohybrid crosses with incomplete dominance
A true-breeding plant is:

| 2. | produced due to cross-pollination among unrelated plants |
| 3. | near homozygous and produces offspring of its own kind |
| 4. | always homozygous recessive in its genetic constitution |
The genotypes of a husband and wife are IAIB and IAi respectively. Among the blood types of their children, how many different genotypes and phenotypes are possible?
1. 3 genotypes; 4 phenotypes
2. 4 genotypes; 3 phenotypes
3. 4 genotypes; 4 phenotypes
4. 3 genotypes; 3 phenotypes
1. Franklin Stahl coined the term "linkage".
2. Punnett square was developed by a British scientist.
3. Spliceosomes take part in translation.
4. Transduction was discovered by S. Altman.
1. Starch synthesis in pea: Multiple alleles
2. ABO blood grouping: Co-dominance
3. XO type sex determination: Grasshopper

The production of gametes by the parents, formation of zygotes, the F1 and F2 plants, can be understood from a diagram called:
1. Punnett square
2. Net square
3. Bullet square
4. Punch square
| List-I | List-II | ||

| A: | Out of one pair of factors, one is dominant and the other is recessive. |
| B: | Alleles do not show any expression and both the characters appear as such in F2 generation. |
| C: | Factors occur in pairs in normal diploid plants. |
| D: | The discrete unit controlling a particular character is called factor. |
| E: | The expression of only one of the parental characters is found in a monohybrid cross. |
| 1. | A, C, D and E only | 2. | B, C and D only |
| 3. | A, B, C, D and E | 4. | A, B and C only |

Topic Frequently Asked Questions
Is Monohybrid Cross 1 a high-weightage topic?
You can refer to the priority and consistency badges at the top of this page. High priority topics should be thoroughly revised multiple times before the exam.
Should I memorize the solutions?
No, it is highly recommended to understand the core concept and methodology behind each solution rather than memorizing them, as exact questions are rarely repeated, but the concepts definitely are.
