A pure-breeding fruit fly with curled wings mates with a pure-breeding fruit fly with normal (straight) wings. The F1 mate with

vesna_86 [32]

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.
