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.
Phenotype: Black Bear x Brown Bear Genotype: BB x bb Possible gametes: B B b b Possible B B crosses: b Bb Bb b Bb Bb Phenotype of offspring: Only Black bears
100% She will either have at least two brown socks or two white socks in any scenario.
I assume you are selecting two socks (one at a time) from the drawer to wear (for example). There are 6 white + 3 black + 3 brown + 8 gray = 20 socks in all So the probability that the first sock chosen to be white is 6/20 since there are 6 socks and 20 socks in total. 6/20 reduces down to 3/10. The probability that the second sock chosen is also white is 5/19 since there are now only 5 white socks left to be chosen and 19 socks in total (since one sock has been taken out). Thus the probability of both socks being white is: probability = 3/10 x 5/19 = 3/38
There's only one color that's equal to brown. That color is . . . brown.
In this case, it doesn't matter what the genotype of the other parent is since BB is homozygous dominant (assuming this is the only gene that affects coat colour of course). All of the BB parent's offspring will PHENOTYPICALLY be brown-coated. They may be heterozygous though (Bb) depending on genotype of the second parent. So the PHENOTYPIC probability of a brown coat is 100% The genotypic probability of a homozygous genotype depends on the second parent.
brown
for what animal. it all depends on the dominant gene (allele) and recessive. the genotype of the parents needs to be set up in a Punnett square and with that data you can determine the probability that an animal will have brown fur
his offspring hair color will be brown

There are so many combinations of traits in offspring because organisms are so complex. Even if somebody has brown eyes, for example, they might have a recessive gene for blue eyes, which they could pass to one or all of their children.
GeneticsYes, it's possible for a pair of blue-eyed parents to have a brown-eyed offspring. It all depends on each parent's genotype, and which trait comes from the dominant or recessive allele.

You have a square the is split into fourths. 2 and 2 in bottom. It looks like a window. On top of the two top squares you put the alleles of the first parent. On the left you put the to alleles of the other parent. And you basically get one allele from each parent and put it in the square and it gives you the probably outcomes of the offspring.
In short from the info given, it could be possible. I wont go into the genetics of it and the probability of it. However if there was more info about the parents of each parent, then you could get an exact yes or no.
Brown, blue, or a mixture making a grayish blueish brown!
No. Blue eyes come from a recessive gene from each parent. The child must of 2 recessive gene pairs to have blue eyes (which is actually the lack of eye pigment). So a brown eyed parent and a green eyed parent may have a blue eyed child if both pass on a recessive blue eye gene, but if just one dominant brown or green eyed gene is passed along it will trump the recessive blue eyed gene and the child will have brown or green eyes.
