In a population of 1000 snails, tests of snail color genes show that 160 snails are AA, 480 are Aa and 360 are aa. What is the f

Kipish [7]

Answer:

Option C.

Step-by-step explanation:

Total population = 1000 snails

AA = 160 snails

Aa = 480 snails

aa = 360 snails

Frequency of each type.

$AA=\dfrac{160}{1000}=0.16$

$Aa=\dfrac{480}{1000}=0.48$

$aa=\dfrac{360}{1000}=0.36$

Now, we get

$A^2=0.16\Rightarrow A=\sqrt{0.16}=0.4$

he frequency of the A allele in this population is 0.4.

Therefore, the correct option is C.

Solve for a and b<br> (6a-3)=(7b-10)

Free_Kalibri [48]

Answer:

for A= $\frac{7b-7}{6}$ and for B= $\frac{6a+7}{7}$

Step-by-step explanation:

For A

$\left(6a-3\right)=\left(7b-10\right)$

$6a-3+3=7b-10+3$

$6a=7b-7$

$\frac{6a}{6}=\frac{7b}{6}-\frac{7}{6}$

$a=\frac{7b-7}{6}$

For B

$\left(6a-3\right)=\left(7b-10\right)$

$7b-10=\left(6a-3\right)$

$7b-10=6a-3$

$7b-10+10=6a-3+10$

$7b=6a+7$

$\frac{7b}{7}=\frac{6a}{7}+\frac{7}{7}$

$b=\frac{6a+7}{7}$
