(a) Show a cross between a pea plant having round & green seed with a pea plant having wrinkled and yellow seeds upto generation.
(b) Also write down results of generation.
(a) Show a cross between a pea plant having round & green seed with a pea plant having wrinkled and yellow seeds upto generation.
(b) Also write down results of generation.
(a) A cross between a pea plant having round & green seed with a pea plant having wrinkled and yellow seeds can be represented as follows:
(b) In the generation, the results will be as follows:
- Round and green seeds: 9
- Round and yellow seeds: 3
- Wrinkled and green seeds: 3
- Wrinkled and yellow seeds: 1
Marking Scheme
- 1(a) 1 mark for correct representation of cross
- 2(b) 1 mark for correct results of generation
Hint
Use the Punnett square to predict the probability of each combination of traits in the offspring.
Quick Oral Answer
The results of the cross between a pea plant having round & green seed with a pea plant having wrinkled and yellow seeds can be represented using a Punnett square. The probability of each combination of traits in the offspring can be predicted using the Punnett square.
Analysis & Explanation
This problem requires the application of Mendel's laws of inheritance to predict the results of a cross between two pea plants. The problem involves the use of Punnett squares to predict the probability of each combination of traits in the offspring.
Common Mistakes
- 1Forgetting to consider the probability of each combination of traits
- 2Incorrectly representing the cross
Interesting Facts
