Question: How did mendel explain that it is possible that a trait is inherited but not expressed in an organism?
Mendel explained that it is possible that a trait is inherited but not expressed in an organism by using the concept of dominant and recessive alleles. He observed that some traits, such as purple flower color in pea plants, were more likely to appear in the offspring than others, such as white flower color. He proposed that each trait is controlled by two factors, or alleles, that are inherited from the parents. One allele can be dominant, meaning that it masks the effect of the other allele, which is recessive. Therefore, an organism can have two alleles for a trait, but only one is expressed. For example, a pea plant can have one allele for purple flower color and one allele for white flower color, but only the purple allele is dominant and determines the phenotype. The white allele is recessive and hidden in the genotype.
