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.
done

Explanation:

Mendel's hypotheses (part of his work in genetics, a subfield of Biology) include:

• A pair of factors (genes) control traits (correct, as traits are controlled by gene pairs).
• One gene (allele) from each parent for every trait (correct, as offspring get one allele from each parent).
• Each trait is passed from generation to generation (correct, as traits are heritable).
• When gametes form, genes (alleles) separate (Law of Segregation, correct).
• If two unlike genes (alleles), one is dominant (seen), one recessive (hidden) (correct, Law of Dominance).

The option "Some traits are passed together" is incorrect (Mendel's Law of Independent Assortment shows traits assort independently, so they aren't always passed together).

Answer:

A. A pair of factors (known as genes) control traits.
B. One gene comes from each parent for every trait.
C. Each trait is passed from generation to generation.
E. When gametes are formed, genes separate.
F. If there are two unlike genes, one may be seen while the other is hidden.
