Question

The genes controlling the seven pea characters studied by Mendel are known to be located on how many different chromosomes?
A. 7
B. 6
C. 5
D. 4

Answer 1

Hint: Johann Gregor Mendel is known as the father of genetics.
Mendel studied the inheritance of seven different features in the pea plant which are the height, color of the flower, the color of the seed shape.

Complete answer: The genes that control the seven pea characters which were studied by the Mendel and were located on the four different chromosomes i.e., 1,4,5,7.
Chromosome 1 locates the genes for the seed color and flower color.
Chromosome 4 locates the genes which are responsible for the height, inflorescence, and the shape of the pod.
Chromosome 5 locates the gene which is responsible for the color of the pod.
Chromosome 7 locates the gene for the shape of the seed.

Hence, the correct option is ‘D’

Additional information: A gene is an important unit of heredity in a living organism. Genes come from our parents. We may inherit our physical traits and the likelihood of getting certain diseases and order from a parent. Genes consist of the data needed to build and maintain cells and pass genetic information to offspring.

Note: Mendel studied all the seven characters of the pea together where all the characters were controlled by the seven pairs of the alleles which was present on the four chromosomes which were located on seven different pairs of chromosomes.
