There are three genes $\mathrm{a}, \mathrm{b}$ and $\mathrm{c}$. The percentage of crossing over between $a$ and $b$ is $20 \%, b$ and $c$ is $28 \%$ and $a$ and $c$ is $8 \%$. What is the sequence of genes on chromosome?

• Correct answer
  A

  $b, a, c$
• B

  $a, b, c$
• C

  $a, c, b$
• D

  None

Solution

The sequence of $a, b, c$ gene is $b, a, c$

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