In $Drosophila$,crossing over occurs in females but not in males. Genes $A$ and $B$ are located on a chromosome at a distance of $10 \ cM$. The genotype of the female $Drosophila$ is $AB/ab$ and the genotype of the male $Drosophila$ is $AB/ab$. How many types of gametes are produced by the female and male $Drosophila$,respectively?

• A
  $4 \text{ types} : 2 \text{ types}$
• B
  $2 \text{ types} : 2 \text{ types}$
• C
  $4 \text{ types} : 4 \text{ types}$
• D
  $4 \text{ types} : 1 \text{ type}$
