Put in your 100 percent concentration when doing practicals in Skool as u loose a lot of marks in them and especially prepare well for mcqs as they are very tough for which u will need to practice a lot and read every word from the book.
Hope it helps

 

[IGCSE MAN]

In a certain organism, two traits are determined by two pairs of alleles, each of which shows dominance. One trait is determined by some combination of the alleles A and a. The other trait is determined by some combination of the alleles B and b, which are located on a different chromosome from A and a. Construct a complete Punnett square to show the results of a cross between two parents with genotypes Aabb (parent #1) and AaBb (parent #2). Then determine each of the following:

a) What fraction of the offspring is expected to have the same genotype as parent #1?
b) What fraction of the offspring is expected to have the same phenotype as parent #2?
c) What fraction of the offspring is expected to be dihybrid?
