Question

find out the result of the dihybrid cross upto f2 generation between the pure lined round yellow seeded plants with pure lined wrinkled green seeded plants. explain the result with the help of an illustration​

Answer 1

Answer:

Dihybrid cross is a cross between two different lines/genes that differ in two observed traits. In the Mendelian sense, between the alleles of both these loci there is a relationship of complete dominance - recessive. In the example pictured to the right, RRYY/rryy parents result in F1 offspring that are heterozygous for both R and Y (RrYy).

Now the question demands the frequency of Round and yellow coloured seeds in F2 generation, which will be possible if the progeny have the genotype of R_Y_, where the blank spaces can be filled by either R or r. The probability of finding a R_ or Y_ genotype is 3/4. So the cumulative result will be (3/4) X (3/4).

So the correct option is '9/16'. ..........please follow me
