In pea plants, the allele for the purple flowers, P, is dominant over the allele for white flowers, p. Which conclusion about phenotype and genotype is possible?

Question

If a plant has white flowers, then its genotype must be Pp.
If a plant has purple flowers, then its genotype must be Pp.
If a plant has purple flowers, then its genotype must be PP.
If a plant has white flowers, then its genotype must be pp.

Answer 1

If a plant has white flowers, then its genotype must be pp.

Answer 2

What is a phenotype of an organism?
a section of DNA
an observable trait
a structure that carries genetic information

Answer 3

An observable trait is the correct definition of a phenotype. It refers to the physical or observable characteristics of an organism, such as its appearance, behavior, or other traits. Phenotypes are influenced by both genetic factors and environmental influences.

Answer 4

What is an allele?
a dominant form of a gene
the location of a gene on a chromosome
the trait a gene controls
a form of a gene

Answer 5

An allele is a form of a gene. Genes exist in different versions, called alleles, which can give rise to variations in a particular trait. For example, in pea plants, the allele for purple flowers and the allele for white flowers are two different forms or alleles of the gene that determines flower color. In a diploid organism, such as humans, an individual inherits two alleles for each gene, one from each parent.
