Questions: What did Mendel call the hidden trait that reappeared in the second generation of plants? dominant intermediate recessive co-dominant What did Gregor Mendel call the trait that was expressed in all the new seeds when he crossed a plant with yellow seeds with a plant with green seeds? dominant co-dominant recessive or co-recessive

The answer to QUESTION 3 is: recessive.

Explanation:

• Dominant: Incorrect. The dominant trait is the one that is expressed in the first generation (F1) and masks the presence of the recessive trait.
• Intermediate: Incorrect. This term is not typically used in Mendelian genetics to describe the hidden trait.
• Recessive: Correct. Mendel called the hidden trait that reappeared in the second generation (F2) the recessive trait.
• Co-dominant: Incorrect. Co-dominance refers to a situation where both alleles in a heterozygous organism are fully expressed, which is not the case here.

The answer to QUESTION 4 is: dominant.

Explanation:

• Dominant: Correct. The trait that was expressed in all the new seeds (F1 generation) when Mendel crossed a plant with yellow seeds with a plant with green seeds is the dominant trait.
• Co-dominant: Incorrect. Co-dominance involves both traits being expressed simultaneously, which is not what Mendel observed in this case.
• Recessive: Incorrect. The recessive trait is the one that is hidden in the F1 generation and reappears in the F2 generation.
• Co-recessive: Incorrect. This term is not typically used in Mendelian genetics.

Summary:

• QUESTION 3: The hidden trait that reappeared in the second generation of plants is called the recessive trait.
• QUESTION 4: The trait that was expressed in all the new seeds when Mendel crossed a plant with yellow seeds with a plant with green seeds is called the dominant trait.
