Q14 / 67 · NEST (NISER) 2021 (Session 1) · Biology

In the given pedigree, circles represent females and squares represent males. Filled shapes indicate affected individuals; while, unfilled shapes indicate unaffected individuals for a particular disease controlled by gene $\mathbf{P}$.
Figure

i. X-linked dominant
ii. Autosomal dominant
iii. Autosomal recessive
iv. The genotype of $\mathrm{I}-2$ is Pp or PP
v. The genotypes of II-2 and III-5 are same for the trait
vi. The genotype of II-7 is Pp or PP

Analyse the inheritance pattern along with the genotype ( $\mathbf{P}$ is dominant allele and $\mathbf{p}$ is recessive allele) and choose the correct options(s).

  • A
    ii and iv
  • B
    iii and vi
  • Correct answer
    C
    ii and v
  • D
    i and vi

Hence, the correct answer is option: 'C'.
