Through reproduction. dark fur is a dominant trait and eventually if offspring of the one dark furred mouse reproduce enough, it will eventually spread to the whole population because it is a dominant gene and will overpower recessive genes of the other parent organism that the dominant mouse is reproducing with.
Answer:
a. 8.1 milligrams
b. 40.07 hours
c. 8.859 milligrams
Explanation:
If a person takes a prescribed dose of 10 milligrams of Valium, the amount of Valium in that person's bloodstream at any time can be modeled by
Where A(t) = amount of Valium remaining in the blood after t hours
t = time or duration after the drug is taken
a. we have to calculate the amount of drug remaining in the bloodstream after 12 hours
= 10×0.81253
= 8.1 milligrams
b. In this part we have to calculate the time when A(t) = 5 milligrams
0.5 = 
Now we take natural log on both the sides of the equation.
ln(0.5) = ln(
-0.69314 = -0.0173t
t = 
t = 40.0658
≈ 40.07 hours
c. In this part we have to calculate the rate, by which amount of drug will decay in the bloodstream after 7 hours.
= 10×0.8859
= 8.859 milligrams
Answer:
Option E, Floppy ears are dominant over straight ears; coat color is determined by incomplete dominance
Explanation:
Let the allele for floppy ears be "F" and the allele for straight ears be "f"
And Let the allele for black coat color be "B" and the color for white coat color be "b"
Now, the cross is carried out between the first group having floppy ears and white coat color (FFbb) and the second group having straight ears and black coat color (ff BB)
The 16 offspring have genotype FfBb
Phenotype of 16 offspring is Floppy ears and grey coat
Ff represents the floppy ear , thus "F" is dominant over "f"
Bb represents the grey color which is a case of incomplete dominance in which none of the real trait i.e black or white is expressed.
Hence, option E is correct
Answer:
Case 1 ⇒ Bb x bb ⇒ F1 = 50% Bb, black + 50% bb, white
Case 2 ⇒ Bb x Bb ⇒ F1 = 75% Black + 25% white
Case 3 ⇒ Bb x Bb ⇒ F1 = 25% BB + 50% Bb + 25% bb
⇒ Bb x bb ⇒ F1 = 50% Bb + 50% bb
Case 4 ⇒ BB x BB ⇒ F1 = 100% BB Black
⇒ Bb x BB ⇒ F1 = 50% BB + 50% Bb = 100% Black
⇒ bb x BB ⇒ F1 = 100% Bb black
Case 5 ⇒ bb x bb ⇒ F1 = 100% bb white
Case 6 ⇒ Bb x bb ⇒ F1 = 50% Bb black + 50% bb white
Case 7 ⇒ Bb x Bb ⇒ F1 = 75% black + 25% white
