On crossing two heterozygous tall plants...

On crossing two heterozygous tall plants (Tt), a total of 500 plants were obtained in `F_(1)` generation. What will be the respective number of tall and dwarf plants obtained of `F_(1)` generation ?

A

`375,125`

B

`250,250`

C

`475,25`

D

`350,150`

Text Solution

Verified by Experts

The correct Answer is:
A

The crossing between two heterozygous plants is as follows

So, if plants obtained were 500, then the respective number of tall and dwarf plants will be 375 tall and 125 dwarf.
