In an experiment on monohybrid cross a geneticist crossed dominant homozygous white mice with homozygous black mice . Using the punnet square , work out F1 & F2 generations and derive the phenotypic and genotypic ratio
Phenotypic ratio : All White, All Genotypic ratio : All Ww
A child has blood group O. If 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. Identify the type of inheritance.
Therefore the genotype of the parents is IA i & I B i The other offsprings will be – AB, B, A, O. Read More …
Which disease there is point mutation , where there is single base pair change in betaglobulin chain of haemoglobin?
Sickle cell anaemia
The sex determination mechanism in grasshopper is : a) XY type b)XO type c)d)ZW type ZZ type
insects it is XO type , so b)
A colour blind man has a normal woman as his wife . Predict the children . Gene for Colour blindness lies in the X chromosome.
Thus the above cross shows that the possible children of a colourblind man and normal woman are carrier daughters and normal sons
Describe in detail The pattern of inheritance in incomplete dominance & co – dominance.
Incomplete dominance : All traits in most organisms did not follow Mendel’s Laws of dominance. Eg.Flower colour in Snapdragon (Antirrhinum sp.): When true-breeding red-flowered Read More …
State Mendel’s law of independent assortment . Explain a Dihybrid cross & its result obtained by him?
Mendel’s Law of Independent Assortment states that when two pairs of traits are combined in a hybrid, segregation of one pair of characters is Read More …
