Question

Choose the correct answer from the four options given below.

The recessive gene is the one that expresses itself in

• A. Heterozygous condition
• B. Homozygous condition
• C. F₂ generation
• D. Y-linked inheritance

Answer 1

The correct option is B

Homozygous condition

The correct option is B:

Explanation of the correct option.

1. Only homozygous individuals with a recessive gene can express it.
2. Homozygous refers to having alleles for a single trait that are identical. An allele also refers to a gene's distinct form. Furthermore, alleles have been found in a variety of forms. Furthermore, for each attribute, diploid organisms have two alleles. During fertilization, alleles unify at random.

Explanation of the incorrect options.

Option A:

1. Heterozygous means you acquired different versions of the same gene from each of your biological parents.
2. Now, when we say distinct forms, we're referring to different parts of the gene with different sequences.

Option C:

1. Individuals who exhibit the consequence of recombination and segregation of genes controlling qualities for which stocks of the P1 generation differ, are formed by interbreeding individuals of an F1 generation.

Option D:

1. Genes on the Y chromosome are passed down through generations. Y-linked genes can only be passed down from father to son since the Y chromosome is only found in males.

Final Answer: The recessive gene is the one that expresses itself in homozygous conditions.
