How do you solve Punnett?

How to Solve a Punnet Square

1. Determine the genotypes (letters) of the parents. Bb x Bb.
2. Set up the punnet square with one parent on each side.
3. Fill out the Punnet square middle.
4. Analyze the number of offspring of each type.

What is the probability that the offspring will have dimples?

a 50% chance

Is BB dominant or recessive?

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.

Is curly hair dominant or recessive?

Since curly hair is a dominant gene, there is a good likelihood that one or two curly-haired parents will produce a curly-haired cutie. But genetics are tricky, and there’s a chance that two parents with curls could carry the straight hair recessive gene, and pass that onto their offspring.

Is blonde hair recessive or dominant?

The Truth About Dominant and Recessive Genes Each parent carries two alleles (gene variants) for hair color. Blonde hair is a recessive gene and brown hair is a dominant gene.

Which parent determines the eye color of baby?

What determines a baby’s eye color? In general, children inherit their eye color from their parents, a combination of the eye colors of Mom and Dad. A baby’s eye color is determined by the parents’ eye color and whether the parents’ genes are dominant genes or recessive genes.
