What is the genotype of a pea plant that shows the recessive phenotype?
Pp
If both heterozygous parents are carriers of a recessive allele for phenylketonuria the probability that a given child of these parents will have PKU is?
Pp x Pp yields PP, Pp, Pp, pp. PP is the only genotype which will cause the phenotypic expression of the gene - symptoms of PKU. Therefore the probability is 1/4 or 25%
If you have a plant with yellow seeds which express a dominant phenotype. How would you determine the plant's genotype?
Identify the genotype trait of the seed color is yellow or green?
Is homozygous dominant a geneotype or phenotype?
homozygous dominant is the genotype. hypothetically, if the gene was for the color purple in a flower, the phenotype would be purple, while the genotype would be homozygous dominant AKA Pp.
What are the results of a cross between parents with genotypes Pp and pp?
Pp 50% and pp 50% .
What is the probability that the offspring will inherit a PP genotype?
It depends on the parents' genes. If both parent have a Pp genotype, then the offspring has a 25% chance of having a PP genotype. But if both parents have a PP genotype then its 100%.
How else can the genotype Pp be written?
PP
If you cross a while flower with the genotype pp with a purple flower with the genotype pp the possible genotypes in the offspring will be what for the cross what would the phenotypes be?
half white and half purple
Why do the genotype Pp and pP all have the same phenotype?
because they all have at least one dominant alleles.
What is the genotype of a pea plant that shows the recessive phenotype?
Pp
If both heterozygous parents are carriers of a recessive allele for phenylketonuria the probability that a given child of these parents will have PKU is?
Pp x Pp yields PP, Pp, Pp, pp. PP is the only genotype which will cause the phenotypic expression of the gene - symptoms of PKU. Therefore the probability is 1/4 or 25%
What is the genotype of the purple plant?
The genotype for a purple plant would be 'PP.' This will depend on whether both parents showed that phenotype, but purple is generally dominant.
If you have a plant with yellow seeds which express a dominant phenotype. How would you determine the plant's genotype?
Identify the genotype trait of the seed color is yellow or green?
What is the genotype of a pea plant that is true-breeding for purple flowers?
The answer is all of the produced flowers would be Pp
Is homozygous dominant a geneotype or phenotype?
homozygous dominant is the genotype. hypothetically, if the gene was for the color purple in a flower, the phenotype would be purple, while the genotype would be homozygous dominant AKA Pp.
When Mendel crossed purebred purple flowering plants PP with purebred white flowering plants pp what were the flower colors of the resulting offspring?
Let us assume that both Rr and rr produce red flowers and only rr produces white flowers. Since one parents and the offspring are white, they have rr as genotypes. In order to achieve this result, the other parent would have to haev at least one r in its genotype. Since the otehr parent is red and needs to have one r, it's genotype is Rr. In short, the parents's genotypes are Rr for the red one and rr for the white one.
A testcross on a tall pea plant produces only tall offspring. What is the genotype of the tall pea plant?
Tt
