Question

Why did gregor mendel use peas in his experiments?peas grow very slowly.pea reproduction cannot be controlled.peas normally produce very few offspring.peas have characteristics that have two forms.

Answer 1

Answer:

The correct answer is peas have characteristics that have two forms.

Gregor Mendel used pea plant  Pisum sativum as a model plant for his experiments. There are many applications behind his choice, one of which is observable characteristics with contrasting traits.

Pea plant has many observable characteristics which exist in two forms for example:

• Plant size (tall or dwarf)
• Pea color (green or yellow)
• Pod shape (yellow or green)
• Flower color (purple or white)
• Pea shape (round or wrinkled)

Other benefits were like: short life cycle, it produces a good number of offspring in a cross, easy to breed or cross-pollinate, hybrids were liable, bisexual flowers which makes it easy to produce true-breeding etc.

Answer 2

Answer: Peas have characteristics that have two forms.Mendel used peas for his experiment because peas were having all the contrasting characters which Mendel wanted to study.Only one single plant having many characteristics such as color, shape , size,etc.

• Explanation:One form such as tall, always concealed the other form, such as short, in the first generation after the cross. Visible form was called dominant and hidden was recessive.

• In the second generation, after plants were allowed to self-fertilize, the hidden form of the trait reappeared in a minority of the plants.

Mendel concluded that the features were inherited independently: one feature, such as plant height, did not influence inheritance of other features, such a.s flower color or seed shape.

• The law of segregation, describing how individual traits are inherited.

• The law of independent assortment, describing how two or more traits are inherited relative to one another
