Answer:
30%
Step-by-step explanation:
The crossing of a male with genotype Dd with a female with genotype dd, yields the following possible outcomes:
Dd, dD, dd, dd.
Therefore, there is a 2 in 4, (50%) chance that their offspring will have the dominant allele. Since its penetrance is 60%, the dominant trait will only manifest itself in 60% of heterozygous individuals. Therefore, the probability that their offspring will have long toes is:

The probability is 30%.
3x+50=6x-10
subtract 3x
50=3x-10
add 10
60=3x
divide by 3
20=x
Answer:
y > 4x + 1
Step-by-step explanation:
Equation of the dotted line:
Slope = (-3-1)/(0-1) = 4
Y intercept is +1
y = 4x + 1
Shaded region:
y > 4x + 1
