A child has blood group O. If the father has blood group A and mother
blood group B, work out the genotypes of the parents and the possible
genotypes of the other offsprings.
What is pedigree analysis? Suggest how such an analysis, can be useful.
Briefly mention the contribution of T.H. Morgan in genetics.
Two heterozygous parents are crossed. If the two loci are linked what
would be the distribution of phenotypic features in F1 generation for a
dibybrid cross?
When a cross in made between tall plant with yellow seeds (TtYy) and
tall plant with green seed (Ttyy), what proportions of phenotype in the
offspring could be expected to be
(a) tall and green.
(b) dwarf and green
Using a Punnett Square, workout the distribution of phenotypic features
in the first filial generation after a cross between a homozygous female
and a heterozygous male for a single locus.
