Question
a pea plant exhibits a recessive trait. which statement is most likely true about the plant?
the plant is identical to its parent plant.
the plant has different alleles for the gene that codes for the trait.
the plant has two identical alleles for the gene that codes for the trait.
the plant does not have the same genes for the trait as its parent plant.
In genetics, for a recessive trait to be expressed in an organism (like the pea plant here), the organism must have two copies of the recessive allele. This is based on Mendelian genetics principles. If an organism has two different alleles (one dominant and one recessive), the dominant trait will be expressed. If it has two identical recessive alleles, the recessive trait is expressed.
