Select the correct statement/s with respect to mechanism of sex determination in Grasshopper. (A) It is an example of female heterogamety. (B) Male produces two different types of gametes either with or without

\mathrm{X}

chromosome. (C) Total number of chromosomes (autosomes and sex chromosomes) is same in both males and females. (D) All eggs bear an additional

\mathrm{X}

chromosome besides the autosomes. Choose the correct answer from the options given below :

Options

A $(A)$ only
B $(A)$ and $(C)$ only
C $(B)$ and $(D)$ only
D $(A),(C)$ and (D) only

Correct answer

C. $(B)$ and $(D)$ only

Step-by-step solution

Grasshopper shows male heterogamety and chromosomal constituent of male is AA + XO and female is

A A+X X

Males have lesser number of sex chromosomes as compared to females. Male produce two types of gametes

(\mathrm{A}+\mathrm{X})

and

(\mathrm{A}+\mathrm{O})
