Answer:
• A pair of factors (known as genes) control traits.
• One gene comes from each parent for every trait.
• Each trait is passed from generation to generation.
• When gametes are formed, genes separate.
• If there are two unlike genes, one may be seen while the other is hidden.
Step-by-step explanation:
The things that Mendel would include in his hypothesis will be genes. This is an hereditary unit that is being passed to.a child from their parents. This gene comes from each parent for every trait and is passed down across different generations. These traits passed down to the child can be height, shape, color of the seed etc.
It should be noted that when the reproductive cells are being formed, the genes will be grouped differently and in situations whereby the gender are not thesame, one will be a dominant gene while the other will be a recessive gene.
