Let's address the questions one by one:

QUESTION 13: Offspring from monohybrid crosses have a $\qquad$ phenotypic ratio in the F2 generation.

• $1: 2$: This is not the correct phenotypic ratio for a monohybrid cross in the F2 generation.
• $3: 1$: This is the correct phenotypic ratio for a monohybrid cross in the F2 generation. In a typical Mendelian monohybrid cross, the F1 generation is all heterozygous, and when these are crossed, the F2 generation shows a 3:1 phenotypic ratio of dominant to recessive traits.
• $4:1$: This is not a typical phenotypic ratio for a monohybrid cross.
• None of the above: This is incorrect because the 3:1 ratio is a standard result.

The answer is the second one: $3: 1$.

QUESTION 14: What is the name given to the first generation of offspring in Mendel's experiments?

• Primary generation: This is not a term used in Mendel's experiments.
• Filial generation: This is a general term for offspring generations but does not specify which generation.
• Fo generation: This is not a standard term used in Mendel's experiments.
• F1 generation: This is the correct term. The F1 generation refers to the first filial generation, which is the first generation of offspring from a cross of two parental lines.

The answer is the fourth one: F1 generation.

In summary, the answers are:

• Question 13: $3: 1$
• Question 14: F1 generation
