Someone answer these 2 for me
Sophie [7]

Answer:

F=dominant, 6 fingers

f= reccessive, 5 fingers

Ff= 6 fingers( contains dominant gene)

if you combine Ff and Ff you get:

25% FF (6 fingers)

50% Ff (6 fingers)

25% ff ((5 fingers)

so only 25% will have 5 fingers (normal)

Answer2:

Dominant=normal hearing

Recessive= deafness

If one parent is RR and the other Rr, the offspring will be:

50% RR

50% Rr

so all the offspring will have normal hearing, and there is 0% of deafness.

Hope it helps!!
