Complete the following sentence with appropriate word:
_______ is the ratio of dihybrid cross.
Select the correct statement from the ones given below with respect to dihydrid cross
In a dihybrid cross, if you get 9:3:3:1 ratio it denotes that ______.
In the F2 generation of a Mendelian dihybrid cross the number of phenotypes and genotypes are ______.
Assertion: When the two genes in a dihybrid cross are situated on the same chromosome, the proportion of parental gene combinations is much higher than the nonparental type.
Reason: Higher parental gene combinations can be attributed to crossing over between two genes.
What is the difference between genetic drift and change due to natural selection?
Sahil performed an experiment to study the inheritance pattern of genes. He crossed tall pea plants (TT) with short pea plants (tt) and obtained all tall plants in F1 generation.
