The probability of off springs that both of them have the same genotype is $\boxed{\frac{{\mathbf{1}}}{{\mathbf{4}}}}$ .

Further explanation:

Probability is defined as the ratio of the number of favorable outcome by the total number of outcomes.

Genotype is the collection of genes of an organism that is responsible for the various genetic traits.

Given:

It is given that there are four alleles ${a_1},{a_2},{a_3},{a_4}$ . A person has two off springs.

Step by step explanation:

Step 1:

The two off springs have this genotype ${a_1}{a_2}\times{a_3}{a_4}$ .

The possible genetic combination of offspring are,

${A_1}{A_3},{A_2}{A_3},{A_1}{A_4},{A_2}{A_4}$

It can be seen that there is total outcome is 4 and the favorable outcome is 1.

Therefore, the probability of each genotype is $\frac{1}{4}$

Step 2:

If the probability of one offspring is $\frac{1}{4}$ .

Then the probability of second offspring is also $\frac{1}{4}$ .

Therefore, the probability of off springs that both of them have the same genotype is $\frac{1}{4}$ .

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is $3\times 8.50=$25.5$

cost of 2 dresses if one cost at $27.50 is $2\times 27.50=$55$

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is $25.5+$55+$17.50=$98
