. With detailed answers and explanations for each chapter, students can strengthen their understanding and prepare confidently for exams. Ideal for CBSE and other board students, this resource will simplify your study experience.How do Mendel’s experiments show that traits are inherited independently?
Mendel gave the law of independent assortment from the dihybrid cross.
Mendel performed an experiment in which he made crosses of pea plant with the round yellow seeds and one with the wrinkled green seeds. And in the F1 progeny, round yellow seeds are dominant over the wrinkled green seeds. And in the F2 generation outcome, he saw all the characters are inherited independently by the use of punnett square that helps to demonstrate the possible combinations of the gametes in F2 progeny. Those independently inherited combinations were round yellow, round green, wrinkled yellow and wrinkled green as shown below :
This punnet square is showing the 16 possible combination of gametes with the phenotypic ratio 9:3:3:1 and 1:2:1:2:4:2:1:2:1 genotypic ratio in F2 generation. Every pair is showing the different characters, showing independent assortment.
In the following crosses write the characteristics of the progeny
| Cross | Progeny |
