How do Mendel's experiment show that traits are inherited independently?
Answers
Answer:
Gregor Mendel did a cross breeding between pea plants for two characteristics.It is called dihybrid cross,In which he cross bred a pea plant with Green round seeds with the pea plant with Yellow wrinkled seeds.[Note:-Green seeds are dominant over yellow ones and Round seeds are dominant over wrinkled ones.]He was surprised to see the result,he saw that Some plants had round seeds of green colour,some had round seeds of yellow colour,some had green wrinkled seeds and some had yellow wrinkled seeds.This clearly suggested that traits were inherited independently by the pea plants.

Answer:
• Mendel showed that traits are inherited independently by performing a cross between two different traits using both dominant and recessive characters on a dihybrid cross.
• A dihybrid cross is one in which two different traits are crossed and studied.
• He crossed two different traits and the result came that neither of the characters is dependent on the other for sorting.
• He crossed a plant with round shape (dominant) and green color (recessive) peas with wrinkled shape (recessive) and yellow color (dominant) peas.
• In the cross, it was observed that the segregation (separation) of traits was not dependent on each other. The plant of the F2 generation has plants with any traits out of the two.
• It was round with green, round with yellow, wrinkled with green and wrinkled with yellow peas.
• It doesn’t matter, that, if one trait was dominant, then other has to be dominant too. It can be either dominant or recessive.
• This is also known as Independent assortment
