Question 1

You have three jars containing marbles, as follows:

jar 1: 600 red and 400 white
jar 2: 900 blue and 100 white
jar 3: 10 green and 990 white

If you blindly select one marble from each jar, calculate the probability of obtaining a red, a green, and a white.

Question 2

We have dealt mainly with only two genes, but the same principles hold for more than two genes. Consider the following cross:

A/a ; B/b ; C/c ; D/d ; E/e × a/a ; B/b ; c/c ; D/d ; e/e

Assuming independent assortment, what proportion of progeny will phenotypically resemble the first parent?

Question 3

Consider the following cross:

A/a ; B/b ; C/c ; D/d ; E/e × a/a ; B/b ; c/c ;D/d ; e/e

Assuming independent assortment, what proportion of progeny will phenotypically resemble either parent?

Question 4

Consider the following cross:

A/a ; B/b ; C/c ; D/d ; E/e × a/a ; B/b ; c/c ; D/d ; e/e

Assuming independent assortment, what proportion of progeny will be genotypically the same as the first parent?

You have three jars containing marbles, as follows:

jar 1: 600 red and 400 white
jar 2: 900 blue and 100 white
jar 3: 10 green and 990 white

If you blindly select one marble from each jar, calculate the probability of obtaining a red, a green, and a white.

Explanation / Answer

1.) Solution: Now in jar 1 total marbles are 1000 and so in other two jars.

So probability of gettting red is 600/1000 [ Because probability = Favourable outcome/Total outcome]

=6/10

Probability of getting green is 10/1000= 1/100

Probability of getting white = 100/1000 = 1/10

So total probability = 6/10 x 1/100 x 1/10

= 6/10000 = 0.0006
