Question

If tetraploid male is crossed with hexaploid female what will be zygote?

• A. $8$
• B. $5$
• C. $4$
• D. $3$

Answer 1

The correct option is B $5$

In zygote formation, half number of the chromosome from male and female get a fuse. If a male is tetraploid (4n), gamete will form 2n and female is hexaploid (6n), gamete will form 3n. In fertilization, 2n and 3n gamete fuse and form the 5n zygote.

So correct option is '5'.
