Question

Alleles for some contrasting traits in a species located on the chromosomes are as follows:


In which of the given cross, recombinants will not be observed in the resultant offspring?
[0.7 mark]

• A. A – Because dihybrid condition is not present
• B. B – Because two genes are not far a part
• C. C – Because both the wild type genes are present on the same chromosome
• D. Both B and C – Because mutated genes are present on the same chromosome

Answer 1

The correct option is A A – Because dihybrid condition is not present

Recombination of genetic material can be analysed by observing the traits in the offspring when the genes involved occur crossing over. Crossing over can be studied in dihybrid condition. Hence, option a is the correct answer.
