In a laboratory population of drosophila, all the males are xsy. among the females, 15% are xixi, 50% are xixs, and 35% are xsxs. assuming random mating, what proportion of male flies in the next generation will be xiy?

Answer from: ERIKALYNN092502

20 % from the next generation will be male XiY

Step-by-step explanation:

females have are XX always and males are XY, so when cross a woman an a man the probability of have a male is 50 %

XX - XY

⇒XX

⇒XY

⇒XX

⇒XY

P (female) = $\frac{2}{4} =\frac{1}{2}$ = 0.5 = 50 %

P (male) = $\frac{2}{4} =\frac{1}{2}$ = 0.5 = 50 %

Then the probability oh have a male XiY is dependent first oh have a male and second that the male will be XiY

The probability of a dependent probability is the product of the probabilities

P (XiY) = P (male) * P (male wit the character Xi)

P (male wit the character Xi) = P (of be XiY from the amount of males from the cross XiXi with XsY) * P (XiXi) + P (of be XiY from the amount of males from the cross XiXs with XsY) * P (XiXs) + P (of be XiY from the amount of males from the cross XsXs with XsY) * P (XsXs)

1. XiXi - XsY

⇒ XiXs (female)

⇒XiXs (female)

⇒XiY (male)

From the 2 male, both can be XiY

P (of be XiY from the amount of males from the cross XiXi with XsY) = $\frac{2}{2} =1$

2. XiXs - XsY

⇒ XiXs (female)

⇒XsXs (female)

⇒XiY (male)

⇒XsY (male)

From the 2 male, one can be XiY

P (of be XiY from the amount of males from the cross XiXs with XsY) = $\frac{1}{2}$

3. XsXs - XsY

⇒ XsXs (female)

⇒XsXs (female)

⇒XsY (male)

From the 2 male,any of them can be XiY

P (of be XiY from the amount of males from the cross XsXs with XsY) = $\frac{0}{2} =0$

P (of be XiY from the amount of males from the cross XiXi with XsY) = 1

P (of be XiY from the amount of males from the cross XiXs with XsY) = $\frac{1}{2}$

P (of be XiY from the amount of males from the cross XsXs with XsY) = 0

P (male wit the character Xi) = $1*\frac{15}{100} +\frac{1}{2} *\frac{50}{100} +0 * \frac{35}{100}$ = $\frac{40}{100}=\frac{2}{5}$

P (XiY) = P (male) * P (male wit the character Xi)

P(XiY) = $\frac{1}{2} *\frac{2}{5} =\frac{1}{5} = 0.2$

20 % from the next generation will be male XiY

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
