Which of the following best describes Mendel's gene idea as concluded from his experiments with pea plants?
A
Genes exist as discrete units that are inherited independently from each parent.
B
Each trait is controlled by a single gene with only one possible allele.
C
All traits are determined by environmental factors rather than inheritance.
D
Traits are blended together in offspring, resulting in intermediate characteristics.
Verified step by step guidance1
Recall Mendel's key conclusions from his pea plant experiments, focusing on how traits are inherited across generations.
Understand that Mendel proposed that traits are controlled by discrete units, which we now call genes, rather than blending together.
Recognize that each gene exists in different forms called alleles, and offspring inherit one allele from each parent independently.
Note that Mendel's principle of segregation states that alleles separate during gamete formation, so each gamete carries only one allele for each gene.
Conclude that Mendel's gene idea emphasizes discrete inheritance units passed independently from each parent, rather than blending or environmental determination.
