Mendel was able to study seven traits in all the pea plants in each generation. which of his hypotheses allowed him to analyze each trait separately?
a) if two different alleles for a gene occur together, one of the alleles may be expressed while the other is hidden.
b) when gametes are formed, each gamete carries only one allele for the gene.
c) there are alternate versions of a alleles called genes.
d) for each inherited trait, there is only one copy of the gene that codes for that trait.

The correct answer is D) For each inherited trait, there is only one copy of the gene that codes for that trait.

Genes are the segment of DNA that code for a specific trait or characteristic of the individual.

According to the law of Independent Assortment, genes responsible for different traits are separated independent of each other during the process of gamete formation.

Thus, out of the given hypothesis, the last one allowed Mendel to analyse each trait separately.

because the light is a great source of energy for the plants to survive. (i hope this )
