julia-pushkina [17]

Answer: C. 0.4

64% of the population have dominant phenotype which means they’re either BB or Bb. The other 36% of the population have bb genotype. If this population is in equilibrium then f(b)=rad0.36=0.6 and as u know f(b)+f(B)=1. So 1-0.6=0.4.

Hope this helps:))

Consider that a certain gene is a maternal effect gene and that the allele for dark brown pigment is incompletely dominant to th
Studentka2010 [4]

Answer:

BB - Dark brown color - (1/4)

Bb - light tan (due to incomplete dominance) - (2/4 or 1/2)

bb - white color - (1/4)

Explanation:

Let the allele for dark brown pigment be represented by "B"

And the let allele for white (no pigment) be represented by "b"

Due to incomplete dominance, the phenotype of heterozygous species would be "light tan"

Genotype of heterozygous female - Bb

Genotype of heterozygous male - Bb

Bb * Bb

BB, Bb, Bb, bb

BB - Dark brown color - (1/4)

Bb - light tan (due to incomplete dominance) - (2/4 or 1/2)

bb - white color - (1/4)

If you are in an emergency and there is no space to the side to steer out of the way of a crash, __________.
lana66690 [7]

The correct answer is controlled braking.

If someone suddenly pulls out in front of the person while driving, the natural reaction is to apply the brakes. Although, this is a good reaction if there is the adequate distance to stop and one applies the brakes accurately.

While in case of emergency stops, one should apply brakes in a way, which will maintain the vehicle in a straight line and permits one to turn if it becomes essential. For this, the person can use stab braking method of controlled braking.

In controlled braking, one applies the brakes as hard as one can without locking the wheels. There is a need to keep steering wheel movements very slight while attempting this. If one needs to make bigger steering amendments or if the wheels lock, release the brakes.
