Q10 / 59 · NEST (NISER) 2020 (Session 1) · Biology

A cross was performed between two parent plants of unknown genotypes. The offspring were segregated based on two flower characteristics i.e. flower colour [magenta $(M)$ or white] and flower position [axillary $(A)$ or terminal] and counted. The two genes responsible for these characters are not linked and segregate independently. Based on the information given in the table, predict the genotypes of the parents.
Figure

  • A
    $M M a a \mathrm{X} m m A A$
  • Correct answer
    B
    $M m A a \mathrm{X} m m A a$
  • C
    $M m A a \times M m A a$
  • D
    $m m A a \times M M a a$

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