explain mendels dehybrid laws by using colour of seeds and shape of seeds as characteristics
Answers
Explanation:
In his dihybrid experiment with pea plant, Mendel crossed two pea plants with a set of two contrasting characteristics, for example- the seed color and the seed shape. He crossed a pea plant with round, green sees with one having yellow, wrinkled seeds. The plants obtained in the F1 generation were then self-crossed and the phenotypic ratio of the plants obtained in the F2 is known as Mendel’s dihybrid ratio, which came out to be 9:3:3:1.
Explanation:
Mendel conducted a dihybrid cross to study that traits are inherited independently. He considered two traits at a time: these were:- seed colour & seed shape in which Yellow colour (YY) and round shape (RR) is dominant over green colour (yy) and wrinkled shape (rr).
These observations led to the formulation of Law of Segregation and Law of Dominance. Mendel took two contradicting traits together for crossing i.e. color and shape of seeds. He chose a round yellow seed and a wrinkled green seed and crossed them. He obtained only round yellow seeds in the F 1 generation.
