Question

Plant AaBbcc is of 30 cm height while plant
aabbcc is of 10 cm. Now find out the maximum
height of the plant :-
1) 60 cm
2) 50 cm
3) 70 cm
4) Data insufficient​

Answer 1

50 cm

please mark me as the brainliest answer

Answer 2

Answer:

Height of the plant will be 70 cm.

Explanation:

The height of plant having genotype aabbcc , i.e. , which has all recessive genes will be the minimum height = 10 cm

Say the Maximum Height will be of having genotype AaBbCc is "x"

Now , we Know contribution of each polygene =

(Max Height - Min Height)/(No of Polygenes)

= (x - 10)/6

So Contribution of Dominant polygene in plants having genotype AaBbcc =

2 * ( x - 10 )/6

Now, Height of plant with genotype AaBbcc = min Height  + Contribution of Dominant polygene

This Height is given as 30 cm

30 = 10 + 2 *(x - 10)/6

30 - 10 = (x - 10)/3

20 * 3 = x - 10

x = 70 cm

Hence, option 3) 70 cm is the correct answer.
