What is the dominant trait for pod color?
-
Green
-
White
-
Yellow
Correct Answer
A. GreenExplanation
The dominant trait for pod color is green. This means that if an organism has one copy of the green allele, it will have green pods. The green trait is dominant over white and yellow, so even if an organism has one copy of the green allele and one copy of either the white or yellow allele, it will still have green pods.Rate this question:

What is the recessive trait for seed color?
-
Green
-
Orange
-
Yellow
-
Purple
-
White
Correct Answer
A. GreenExplanation
The recessive trait for seed color is green. This means that in order for a seed to have a green color, both of its alleles must be for green seed color. If an allele for any other color (orange, yellow, purple, or white) is present, it will dominate over the green allele and the seed will not be green.Rate this question:

What is the dominant trait for a flower position?
-
Axial
-
Nodal
-
Terminal
-
Basal
-
Panic (wide spread)
Correct Answer
A. AxialExplanation
The dominant trait for a flower position is axial. Axial refers to flowers that are positioned along the axis or stem of the plant. This means that the flowers are arranged in a way that they grow directly from the stem or main branch of the plant.Rate this question:

Inflated pod shape is a recessive trait.
-
True
-
False
Correct Answer
A. FalseExplanation
The statement suggests that the trait of inflated pod shape is a recessive trait. This means that the trait is only expressed when an individual inherits two copies of the recessive allele for inflated pod shape. If the trait was dominant, it would be expressed even if an individual only inherited one copy of the dominant allele. Therefore, the correct answer is False, indicating that inflated pod shape is not a recessive trait.Rate this question:

-
Gregor Johann Mendel
-
Robert Hooke
-
T.A. Knight
-
Anton van Leeuhoek
Correct Answer(s)
A. Gregor Johann Mendel
A. T.A. KnightExplanation
Gregor Johann Mendel and T.A. Knight are the correct answers for scientists who used Pisum sativum in their research in the field of genetics. Gregor Johann Mendel is known as the father of genetics and conducted extensive experiments on pea plants to study the inheritance of traits. He discovered the principles of inheritance and formulated the laws of Mendelian genetics. T.A. Knight, on the other hand, also conducted research on pea plants and made significant contributions to the understanding of plant breeding and genetics. Both scientists recognized the value of Pisum sativum as a model organism for studying genetic traits and inheritance patterns.Rate this question:

What is the dominant trait for plant height?
Correct Answer(s)
tallExplanation
The dominant trait for plant height is tall. This means that if a plant has at least one allele for tall height, it will exhibit the tall phenotype. The trait for short height is recessive, so a plant must have two alleles for short height in order to be short. Since tall is the dominant trait, it will be expressed in the presence of even one allele for tall height.Rate this question:
- 10.
White is the flower color for the Pisum sativum displaying a recessive trait?
-
True
-
False
Correct Answer
A. TrueExplanation
The explanation for the given correct answer, which is True, is that in Pisum sativum, the flower color displaying a recessive trait is indeed white. This means that the white flower color is the result of a recessive gene, which is not expressed in the presence of a dominant gene. Therefore, when both alleles for flower color are recessive, the flower color will be white.Rate this question:

What is the dominant trait for the Pisum sativum seed color?
-
White
-
Green
-
Blue
-
Yellow
Correct Answer
A. YellowExplanation
The dominant trait for the Pisum sativum seed color is yellow. This means that if an organism has a yellow seed color, it will pass on this trait to its offspring. The other options, white, green, and blue, are not the dominant traits for seed color in Pisum sativum.Rate this question:

Terminal flower position is a recessive trait in (Pisum sativum) garden peas.
-
True
-
False
Correct Answer
A. TrueExplanation
Terminal flower position being a recessive trait in garden peas means that the trait is only expressed when an individual inherits two copies of the recessive allele for terminal flower position. If an individual inherits one copy of the recessive allele and one copy of the dominant allele, the dominant allele will mask the expression of the recessive trait. Therefore, the statement "Terminal flower position is a recessive trait in garden peas" is true.Rate this question:

What is the color of the garden pea pod if it is recessive?
Correct Answer
yellowExplanation
If the color of the garden pea pod is recessive, it means that the allele responsible for the yellow color is not dominant over the allele for a different color. Therefore, the garden pea pod will be yellow in color.Rate this question:
- 15.
Which of the following characters is NOT found in the Pisum sativum?
-
Flower Color
-
Plant Height
-
Stem Shape
-
Seed Color
-
Pod Color
Correct Answer
A. Stem ShapeExplanation
The stem shape is not a characteristic that is found in Pisum sativum. This plant species is known for its various traits such as flower color, plant height, seed color, and pod color. However, the shape of the stem is not mentioned or considered as a defining characteristic of Pisum sativum.Rate this question:
-
- 16.
What is the dominant trait for pod shape?
Correct Answer
inflatedExplanation
The dominant trait for pod shape is "inflated." This means that when an organism inherits this trait, their pods will have a swollen or puffed-up appearance. This trait is dominant, which means that if an organism has even one copy of the gene for inflated pod shape, it will be expressed in their phenotype.Rate this question:

A genetic cross was made in the parent generation between a pure purple flower color and a pure white flower color in Pisum sativum. What is the dominant color in the F2 generation?
-
Green
-
Purple
-
White
-
Yellow
Correct Answer
A. PurpleExplanation
In genetics, the term "dominant" refers to a trait that is expressed when present, even if there is only one copy of the gene. In this case, the parent generation had a pure purple flower color and a pure white flower color. Since purple is mentioned as the dominant color, it means that the purple color trait will be expressed in the F2 generation. Therefore, the dominant color in the F2 generation would be purple.Rate this question:
