Is it possible that the cross between two black guinea pigs?

Is it possible that the cross between two black guinea pigs?

Is it possible that the cross between 2 guinea pigs in punnett square A would not produce a white guinea pig? Explain. yes, because it is possible that they could be black or white.

What is the probability that an offspring will have white fur?

a 25%
Because the genotype aa results in the white fur phenotype, there is a 25% probability that the offspring will have white fur.

What is the probability that the offspring will be yellow?

When counting all four possible outcomes, there is a 3 in 4 probability of offspring having the yellow phenotype and a 1 in 4 probability of offspring having the green phenotype.

What is the probability that an offspring will be brown?

50 percent
Divide the number of boxes with a dominant allele by four and multiply the result by 100 to get the percent chance that an offspring will have the dominant trait. For example (2/4)*100 = 50, so there is a 50 percent chance of an offspring having brown eyes.

What is the probability of getting a black purebred offspring from this cross?

Reading Punnett Squares and Pedigree Charts

A B
What are the genotypes of the parents in this cross?, Bb
What is the probability of black offspring in this cross?, 75% – both BB and Bb will give black offspring
What is the probability of white offspring in this cross?, 25% – the bb guinea pig

What percentage of the offspring will have black fur quizlet?

What are the predicted phenotypes of their offspring? 50, percent of the offspring will be black, and 50%50\%50%50, percent of the offspring will be black-and-white.

What is the allele for white fur?

Finally, the albino, or “colorless” phenotype, cc, is expressed as white fur. In cases of multiple alleles, dominance hierarchies can exist. In this case, the wild-type allele is dominant over all the others, chinchilla is incompletely dominant over Himalayan and albino, and Himalayan is dominant over albino.

What is genetic probability?

In genetics, theoretical probability can be used to calculate the likelihood that offspring will be a certain sex, or that offspring will inherit a certain trait or disease if all outcomes are equally possible. It can also be used to calculate probabilities of traits in larger populations.

How do you calculate genetic probability?

The empirical probability of an event is calculated by counting the number of times that event occurs and dividing it by the total number of times that event could have occurred.

How do you calculate phenotype probability?

Step 5: Calculate Phenotypic Probabilities Count the total number of boxes in your Punnett Square. This gives you the total number of predicted offspring. Divide the (number of occurrences of the phenotype) by (the total number of offspring). Multiply the number from step 4 by 100 to get your percent.

What’s the probability of a guinea pig having brown fur?

Solve Write the probability of the offspring with brown fur as a ratio: Convert to percentage: Answer: 2:4 50% 50% chance of offspring with brown fur This Punnett square shows a cross between two Bbguinea pigs. What is the probability of the cross resulting in offspring with black fur?

Is it possible the cross between 2 guinea pigs in Punnett square a?

Is it possible that the cross between 2 guinea pigs in punnett square A would not produce a white guinea pig? Explain. yes, because it is possible that they could be black or white. What color are the guinea pigs in punnett square B?

What happens if you cross a guinea pig with a white guinea pig?

If a black guinea pig is crossed with a white guinea pig and the litter contains a white offspring, the genotype of the black-haired parent is probably heterozygous What is not an allele combination that could be found in a gamete formed by a parent with the genotype HHRr?

Which is dominant black fur or white fur in guinea pigs?

In guinea pigs, black fur is dominant. If a black guinea pig is crossed with a white guinea pig and the litter contains a white offspring, the genotype of the black-haired parent is probably heterozygous What is not an allele combination that could be found in a gamete formed by a parent with the genotype HHRr?
