How does probability help explain the results of a genetic cross?
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.
How is probability used in biology?
It's used commonly to estimate the traits of a child of two parents. For example, the probability of the child having blue eyes, or curly hair, or even having genetic disease.
Five women live together in an apartment Two have blue eyes If two of the women are chosen at random what is the probability that they both have blue eyes?
well lets look at the probability on your first pick you will get a blue eyed girl 2 have blue out of 5, so yo uhave a 2/5 chance, or 40% on your second pick, there are 4 girls left, and one of them will have blue eyes now 1 have blue out of 4, so 1/4 or 25% so you multiply the two probabilities to get your final sequential probability 2/5 * 1/4 find a common denominattor, for this we will use 20 8/20 * 5/20 = 40/400 simplify it you get 1/10 0.10, or 10% chance
What percentage of Americans have blue eyes?
One out of six white Americans have blue eyes.
What is the percentage of people have blue eyes?
In the United States, one out of every six whites has blue eyes.
Can a baby have brown eyes if the mother has brown eyes but the recessive gene for blue eyes and the father has blue eyes?
Eye color is actually not controlled by straight Mendellian genetics. However, based on your question, the probability of a brown eyed child would be 50% and the probability of a blue eyed child would be 50%.
Can a green eyed man and brown eyed woman have a green eyed daughter?
Yes. Blue eyes are a recessive genetic trait, which means that a brown- or green-eyed person can still carry a gene for blue eyes. In this case, the blue-eyed gene is recessive, or subordinate, to the green- or brown-eyed gene. To be blue-eyed, an individual must have a recessive blue-eyed gene from both its mother and father.
