Question

The production of gametes by the parents, the formation of zygotes, and the F1 and F2 plants, can be understood from a diagram called

• A. Bullet square
• B. Punch square
• C. Net square
• D. Punnett square

Answer 1

The correct option is D

Punnett square

The correct option is D.

The explanation for the correct option:

1. The genotypes of a specific cross or breeding experiment are predicted using the Punnett square, a square diagram.
2. It bears Reginald C. Punnett's name, who developed the method in 1905.
3. Biologists use the figure to calculate the likelihood that a child will have a specific genotype.
4. An effective tool for predicting the variations and probabilities that can result from cross-breeding is a Punnett Square.
5. This includes foreseeing the mating of different species, including humans and animals.
6. The total number of boxes in Punnett Square are counted then this provides us with the total number of offsprings.
7. Count the number of occurrences of phenotypes of interest then divide it by the total number of offspring.
8. To get the percentage of a particular phenotype, multiply the value we obtained by dividing the count of the number of occurrences of phenotypes of interest by the total number of offspring.

Final answer: The production of gametes by the parents, the formation of the zygotes, and the F1, and F2 plants, can be understood from a diagram called Punnett square.
