Which genotypes are homozygous and which are heterozygous?
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.
What does heterozygous and homozygous mean in Punnett Squares?
When talking about Punnett squares, it is important to know what the terms heterozygous and homozygous mean. Heterozygous refers to a genotype with two different alleles (i.e. Bb, Rr, etc.) and homozygous refers to a genotype with two of the same alleles (i.e. BB, bb, etc.).
What is Punnett Square in genetics?
The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given. In its simplest form, the Punnett square consists of a square divided into four quadrants.
What’s heterozygous and homozygous?
Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent.
What is a heterozygous and homozygous?
What genotype do both parents have?
Each parent contributes one allele to each of its offspring. Thus, in this cross, all offspring will have the Bb genotype. Each parent contributes one allele to each of its offspring. Thus, in this cross, all offspring will have the Bb genotype.
Are there guinea pigs in Punnett square B?
Explain. yes, because it is possible that they could be black or white. What color are the guinea pigs in punnett square B? white and black which guinea pig parent(s) in punnett square B is homozygous? which is heterozygous? explain how you know.
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?
Why are offspring on the top of Punnett square B?
The side because they are the same. The top because they are different. Calculate the probability that an offspring will be black in the cross in punnett square B.

Why is the BB a heterozygous hybrid?
The Bb is heterozygous because it is a hybrid and its alleles are both different from each other. What is the probability that an offspring will be BLACK in the cross shown in punnett Square B?
