Question

Before testing the pea plants, Mendel formed a five-part hypothesis. What did Mendel include in his hypothesis? Check all that apply. 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. Some traits are passed together 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.

Answer 1

Mendel included the following in his hypothesis: 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. The inheritance of each trait is determined by units or factors that are passed on to descendants unchanged, and individual inherits one such unit from each parent for each trait, a trait may not show up in an individual but can still be passed on to the next generation and also the genes for each trait segragate themselves during gamete production.

Answer 2

Answer: Mendel's five-part hypothesis can be described as follows-

1) Genes ( that he called as a pair of factors) control particular characteristics/ traits of an organism.

2) One gene corresponds to one particular trait.

3) Traits are passed from  (e.g..plant height, seed color and shape) parents to their offspring in the form of genes.

4) When gametes (that is reproductive cells) are formed, the genes are segregated from one another so that each gamete has one variant of a gene ( allele).

5) If there are two different genes for a trait, one is expressed ( dominant) and other is hidden ( recessive).

Thus, the correct statements are -

• 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.
