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?
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
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.
Blue-eyed blonde mates with brown-eyed brunette?
Their offspring could inherit a combination of traits from both parents, such as blue eyes from the blonde parent and brown eyes from the brunette parent. Hair color could also vary between blonde and brunette. The resulting offspring's eye color and hair color would depend on the specific genetic combinations inherited from each parent.
A male rabbit has white hair a female has brown hair What do you think the most likey color of their offspring is?
I personally think would be brown, because (a. brown is mostly a dominant trait, and (b. the female's genes are normally more dominant than the male's. But, it could possibly be a mix of brown and white, and that is most likely the correct answer.
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 black and brown rabbit mate out of 4 offspring how may would be dark brown?
If a black and brown rabbit mate, their offspring could potentially have a mix of black, brown, and dark brown fur. It is not possible to predict exactly how many offspring would be dark brown without knowing the genetics of the parents. Each offspring has a different combination of genes that determine its fur color.
If a homozygous dominant parent and a heterozygous parent are crossed what percentage of the offspring are expected to be homozygous dominant?
Rr
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.
What is the offspring brown bird pelican?
three
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.
