Don’t worry this is pretty easy :)

The answer is -
50% recessive alleles
50% dominate alleles

explication- find out what alleles you’re working with (heterogeneous and homogeneous)

We’re working with a parent with heterogeneous and another parent with recessive homogeneous.

draw a allele chart
__
|_|_|
|_|_|
they look like this and take your first parents alleles and put them at the top

L s
_ _
|_|_|
|_|_|

it should look like this, then take your parent with both recessive and put them vertical to the box

L s
_ _
s |_|_|
s |_|_|

it should look like this, now you drag one letter down and one letter across for each box

L s
__ __
s|Ls|ss |
s|Ls|ss |

TRY TO LEARN THE VOCABULARY IT HELPS A LOT AND BASICALLY TELLS YOU THE ANSWERS!
GOOD LUCK :)

kolbaska11 [484]

Answer:

c. A to K

Explanation:

If the alanine mutation is restored to K or lysine residue, most likely the wild type level of activity can be restored. This is because, arginine and lysine have -NH2 as the functional group. So, functional similarity of arginine can be expected from lysine as well.

Hence the correct option is c that is A to K.
