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.
A homozygous dominant black bear is mated with a recessive brown bear what phenotype will probably result in the offspring of the two bears?
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
Mammu has 16 pairs of white socks and 16 pairs of brown socks she kept all socks in same drawer she picks out 3 socks at random what is the probability she will get a matching pair?
100% She will either have at least two brown socks or two white socks in any scenario.
Which shows the probability of choosing 2 white socks from a drawer having 6 white 3 black socks 3 brown socks and 8 gray socks?
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
What 2 colors equal brown?
There's only one color that's equal to brown. That color is . . . brown.
How would the probability of a brown-coated offspring change if the brown coated parent had the gene BB?
If the brown-coated parent has the gene BB, then they can only pass on a dominant brown allele to their offspring. Therefore, all offspring from this brown-coated parent would inherit the brown allele, resulting in a 100% probability of having brown coats.
If you had two parent guinea pigs each with brown fur what color fur might the offspring have?
brown
What percent of the offspring will most likely have brown fur?
If brown fur is a dominant trait in the offspring's parents, then approximately 75% of the offspring will most likely have brown fur. This is because there is a 75% chance that each offspring will inherit at least one dominant brown fur gene from the parents.
What is the probability that heterozygous black coated mom and brown coated dad will have a brown coated baby?
Assuming coat color is determined by a single gene with black being dominant and brown being recessive, the probability of a heterozygous black coat (Bb) mom and brown coat (bb) dad having a brown coat baby (bb) is 50%. This is because each parent can pass on either the dominant black allele (B) or the recessive brown allele (b) to their offspring, resulting in a 50% chance of inheriting the brown allele from both parents.
What would be the observable color of the offspring if both chromosomes coming from the parents has brown hair color?
his offspring hair color will be brown
If a homozygous dominant parent and a heterozygous parent are crossed what percentage of the offspring are expected to be homozygous dominant?

Why is there so many combinations of traits in an offspring?
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.
Why are Punnett squares useful in genetics?
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.
Could two blue-eyed parents have a brown-eyed child?
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.
What is the offspring brown bird pelican?
three
Is it possible to have a red haired baby with bule eyes if the parents both have brown hair and brown eyes?
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.
Do blue and green eyes can make 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.
