1)Which of the following was Mendel able to discover by following two characteristics together through successive generations, that he could not observe by following only one? The number of chromosomes present in parent cells.

The presence of dominant and recessive traits.

Organisms can produce gametes that are different from the ones they themselves inherited.

That characteristics are linked together on chromosomes.

2)What was Gregor Mendel able to hypothesize following his early experiments following only one characteristic?
For each characteristic, an individual must inherit two genes - one from each parent.

If an individual inherits two different alleles for a characteristic, it is the dominant allele that will determine which trait is exhibited.

A gamete must only contain one allele for each inherited characteristic.

All of the above
