Question

Genetics experiments on the breeding of plants or animals are based on the laws of _____.

a. segregation
b. isolation
c. genetics
d. probability

Answer 1

The correct answer is - option D.

Step-by-step explanation:

Probability is law that used to calculate or the measure the likelihood or chances of a particular event or in genetics what are the chances of a particular cross to occur .

Role of probability in segregation of allele and fertilization by predicting the chances of expression of dominant trait by its frequency of occurring in a particular cross.

Thus, the correct answer is - option D.

Answer 2

The correct answer is d. probability

Step-by-step explanation:

In genetics, we use laws of probability to determine the probable result of a genetic experiment. For example, the product rule of probability in genetics is very useful which can be used to find out the probability of two independent events that occur together by multiplying the probability of individual events.

This rule can be used to predict the probability of fertilization event. For example in a heterozygous parent(Aa) probability of getting an aa offspring is I/4 because each parent has half 1/2 chance to contribute a gamete so by multiplying both probability, we get 1/4(1/2*1/2).
