Genetics often involves dominant and recessive alleles. For instance, blue eyes are recessive and brown eyes are dominant.1 Each parent contributes one allele. If you get two blues, then your eyes are blue. If you get one or two browns, then you eyes are brown. That means that, given a random contribution from your parents, you have a 25% probability of blue eyes.
It also means that, even though you have brown eyes, you could be carrying the blue allele, and two parents with brown eyes could have a blue eyed child.

1Its more complicated than that, since eye color is actually polygenic, involving more than one allele. This example was simplified to answer the question.

What is probability and how does it help explain the result of crosses?
Probability is a number that describes how likely it is that an event will occur.
What happens when experimental probability is repeated?
You obtain an estimate of the probability that will usually be different from previous result(s).You obtain an estimate of the probability that will usually be different from previous result(s).You obtain an estimate of the probability that will usually be different from previous result(s).You obtain an estimate of the probability that will usually be different from previous result(s).
What is the probability that the result will be 3 or greater?
in what?
What do we call a chart that shows all of the possible genetic crosses?
A Punnett square is a chart used to show all possible combinations of alleles that can result from a genetic cross. It helps predict the probability of traits being passed on to offspring.
What is the probability in percent that a single coin toss will result in heads and tails?
The probability is 0%. The result will be heads or it will be tails but it cannot be heads and tails.
A probability found as a result of an experiment?
Probability determined as part of an experiment is called experimental probability. Probability determined by analysis of all of the possible and expected outcomes is called theoretical probability.
Offspring that result from crosses between parents with different traits?
genes
What best describes what the mishap probability component is?
the mishap probability component is an estimation that a hazard will result in a mishap
Why are some men larger then others?
It is completely a result of genetics.
What is an outcome in a probability experiment?
It is the result of the experiment. It is the value of the observation.
What is the experimental probability that the next toss and spin will result in 3 and tails?
The experimental probability, by definition, can only be determined after you have carried out the experiment!
What is the probability that going to a thai restaurant would result in indegestion?
