5 0

<span>Cork cells are plant cells on the outer edge of the trunks/limbs of woody plants. The cell wall is made of suberin, which doesn't let gas or water through. In essence, this helps keep the water in and unwanted things (like pathogens) out. The inside of the cell is usually empty, but may have a few traces of things depending on species. These cells don't replicate and are generally considered to be dead.</span>

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.
