Pretty good, of both parents have blue eyes.
There is no way to actually predict the answer. You an figure the "odds" of Karen having blue eyed children, but not actually predict the outcome. For example In a family where 3 out of 4 grandparents had blue eyes and 1 of 2 parents had blue eyes - the couple had two children, both of which had brown eyes. Another couple with the same statistics had one child with blue eyes. Another couple with the same statistics had 2 blue eyed children. The "Odds" are dependent on a concept called recessive and dominant genes. The gene for blue eyes is "recessive". Which means a baby must get 1 gene for blue eyes from BOTH parents in order to have blue eyes. Because 1 parent has brown eyes, we know that parent has at least 1 dominant brown eyed gene. So one parent has Br b combo (BR=brown b=blue). The other parent has blue eyes so has a b b combination. Of course, the brown eyed parent may have two brown eyed genes and no blue eyed genes. Go figure. Any way, the chances of having a blue eyed baby is slimmer than having a brown eyed baby. How you get a green eyed baby.....I don't know. Finally - some consolation: All babies are born with blue eyes, so while it may be short lived, enjoy it while it lasts
50/50 if the gene runs in your family
Every one who has ever been born has a family history, no matter what their circumstance.
Sometimes. It depends on the ancestrial origin of the parents. For example, if the mother of the mother had blue eyes, the baby may be prone to adopt blue eyes. None of the parents, as far back as can be traced, could display the blue-eyed trait and the child still have blue eyes, since it's recessive. It is all genetics, since blue eyes are the recessive trait, they may have been passed down from generation to generation, and just not paired with another recessive gene. The odds are slim, but it's possible. Basically, it depends on the parents alleles. If either are homozygous dominant, the eyes will definantly be brown. If they are both heterozygous, then the eyes may be blue, but they may also be brown. There's a 25% chance in that case for blue eyes.
It's absolutely possible, and I am living proof of it. The chances are extremely slim though, because both the trait for blond hair and the traits for green eyes are recessive. Green eyes are the rarest eye color, because green eyes are not only recessive to the brown eyes trait but also recessive even to blue eyes. I couldn't give exact odds, because the process of genetic recombination is random, but if both traits existed somewhere earlier in the family line, (one parent or more is a carrier) then the combination is not impossible. Even with blond haired people, most tend to exhibit either blue eyes or brown because of green's recessiveness to the two. Having the most recessive eye color trait and the second rarest hair color in the world appear together in one person is exceptionally rare though, but still possible.
The odds of a four-child family having four boys can be calculated using the probability of each child being a boy, which is typically 1/2. Therefore, the probability of having four boys in a row is (1/2) × (1/2) × (1/2) × (1/2) = 1/16. This means the odds against having four boys are 15 to 1, as there are 15 other combinations of boys and girls possible in four children.
The odds of having sextuplets are 1 in 3,939,040,643.
most likely yes. but if you both have the eye genotype Hh the odds of having a child with hazel eyes is 75% but also if one has the genotype Hh but the other has HH the odds are 100% here's the punnet squares (never mind turned out bad) hopefully (but not likely) you understood that. the better answer is most likely yes unless you both have the Hh genotype it might be better to see like a doctor about something like this because it would invove a lot of family history and probably some tests
When you have two alleles (coding sequences) from genes that are at odds with each other, one version will override the other. When dealing with eye color, brown overrides blue.
The odds of rolling snake eyes (two ones) on a pair of dice is 1 in 36, since there are 36 possible outcomes when rolling two dice. To find the odds of rolling snake eyes twice in a row, you multiply the probabilities: ( \frac{1}{36} \times \frac{1}{36} = \frac{1}{1296} ). Therefore, the odds of rolling snake eyes twice in a row are 1 in 1296.
Assuming the red and blue spinner has an equal number of red and blue spots, the odds of spinning blue is 50%. On the other spinner, the odds of an odd number is 67%. Combined, the odds of spinning blue and an odd number is 33%. (50% times 67%)
The fact that twins run in families is actually a myth. The odds of twins having twins is the same as a non-twin having twins. That is about 1 in 33.
