Question

In Mendel’s seven characters of Pea, the total number of colors tested by him was _ _ _ _ _
A. 2
B. 3
C. 4
D. 5

Answer 1

Hint:- Mendel considered the nursery pea (Pisum sativum) for two principle reasons. To start with, peas were accessible from seed shippers in a wide exhibit of particular shapes and shadings that could be effectively distinguished and investigated. Second, peas can either (self-fertilize) or are cross-pollinated.

Complete Answer:- Mendel picked seven unique characters to consider. The word character in such manner implies a particular property of a life form; geneticists utilize this term as an equivalent for trademark or characteristic.
For every one of the characters that he picked, Mendel got lines of plants, which he developed for a very long time to ensure that they were unadulterated. An unadulterated line is a populace that breeds valid for (shows no variety in) the specific character being examined; that is, all posterity created by selfing or intersection inside the populace are indistinguishable for this character. By ensuring that his lines reproduced validly, Mendel had made a shrewd start: he had set up a fixed benchmark for his future examinations so any progressions watched resulting to consider control in his exploration would be deductively important; essentially, he had set up a controlled trial.
Mendel chose 14 genuine rearing pea plant assortments, assets that were comparable aside from one character with differentiating qualities.

S. No	Character	Contrasting Attributes	Chromosome Number
1	Stem Structure	Tall/short	4
2	Flower Position	Axial/terminal	4
3	Flower Color	Violet/white	1
4	Pod Shape	Inflated/Contracted	4
5	Pod Color	Green/Yellow	1
6	Seed Shape	Round/Wrinkle	7
7	Seed Color	Green/Yellow	1

Out of these seven characters, Mendel only chooses three characters i.e. Pod Color, Seed Color, and flower color to complete his work.

Note:- Mendelian proportions, (for example, 3:1,9:3:3:1,1:1:1:1) were broadly detailed, recommending that equivalent isolation and autonomous variety are basic inherited cycles found all through nature. Mendel's laws are not simply laws about peas, however, laws about the hereditary qualities of eukaryotic living beings when all is said and done. The trial approach utilized by Mendel can be broadly applied in plants.
