This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.

Does the genotypes and phenotypes are likely to occur at different frequencies in both the original and reduced population because of genetic drift?

Yes, genetic drift can cause changes in the frequency of genotypes and phenotypes in a population over time. In a small population experiencing genetic drift, certain genotypes and phenotypes may become more common by chance, while others may be lost. This can lead to differences in the distribution of traits between the original and reduced population.


Is the probability assigned to an event that is certain not to occur is 1.0?

No; if it is certain not to occur the probability is 0.


What is theoretical probability?

the probability a certain event will occur :-)


Why probability is equal to one?

One is the probability, or certain to occur.


What is the likelihood a certain event will occur?

Its probability. The probability for a certainty is 1.


Probability of an impossible event is?

an impossible event has a probability of 0, it will never occur a certain event has a probability of 1, it will always occur


What does it mean if a number has a probability of 1?

If a number has a probability of 1 it means it is certain to occur.


If the probability that an event will occur is 1 then the event is certain to occur?

Yes, the probabilty scale is from one to zero so is the probability is 0 it will definitely not occur


What do you mean by probability?

Probability is a measure of the expectation that an event will occur or a statement is true. Probabilities are given a value between 0 (will not occur) and 1 (will occur).[1] The higher the probability of an event, the more certain we are that the event will occur.
