Answer:
The dominant curled wing allele is also a recessive lethal.
Explanation:
If we look at the F2 ratio we see that :
curled wings: straight wings= 160:80
=2:1
Hence, if curled wings is considered to be a dominant trait then Curled wings * straight wings
Dd x dd
Punnet square will be as follows :
d d
D | Dd | Dd
d | Dd | dd
Hence in order to get F2
Dd x dd
Punnet square will be the same as above if the F1 cross is Dd* Dd
D d
D DD Dd
d Dd dd
if DD is lethal then the ratio is
Dd:dd=2:1
that is curled wings: straight wings=2:1
Hence, The dominant curled wing allele is also a recessive lethal.
I believe this will help you.
