(a)Describe the possible mode of inheritance of the character shown in the diagram? (b) Give the possible genotypes of H,C,I,J and K?
Provided is a pedigree diagram showing the inheritance of the polydactyl traitin human beings. The dark shapes show individuals expressing the trait and the clear shapes show individuals not affected. Use the letters P and p to refer to the allele for the trait.

(a) The possible mode of inheritance of the character shown in the diagram is autosomal recessive. This is because the trait is not present in the parents but appears in the offspring, indicating that it is a recessive trait that requires two copies of the gene to be expressed.
(b) The possible genotypes of H, C, I, J, and K are as follows:
- H: hh (homozygous recessive)
- C: CC (homozygous dominant)
- I: II (homozygous dominant)
- J: Jj (heterozygous)
- K: KK (homozygous dominant)
(b) The possible genotypes of H, C, I, J, and K are as follows:
- H: hh (homozygous recessive)
- C: CC (homozygous dominant)
- I: II (homozygous dominant)
- J: Jj (heterozygous)
- K: KK (homozygous dominant)

(a) Possible Mode of Inheritance:
The diagram shows a cross between a homozygous dominant individual (HH) and a homozygous recessive individual (hh), resulting in all heterozygous (Hh) offspring. This suggests an autosomal dominant mode of inheritance.
(b) Possible Genotypes:
- H: HH
- C: hh
- I: Hh
- J: Hh
- K: Hh
