what is the gene pool?

• a part of a chromosome that encodes an rna or protein product in its dna sequence
• all of the alleles of all the genes in a population
• forms of a gene with slightly different dna sequences that may encode slightly different versions of the gene product
• the abundance of a particular allele among members of a population

Explanation:

Define the term gene pool

The gene pool represents the entire collection of unique alleles present within an interbreeding population.

Analyze the given options

• Option 1: "A part of a chromosome that encodes an RNA or protein product..." describes a gene.
• Option 2: "All of the alleles of all the genes in a population" matches the definition of a gene pool.
• Option 3: "Forms of a gene with slightly different DNA sequences..." describes alleles.
• Option 4: "The abundance of a particular allele..." describes allele frequency.

Connect to genetic variation

Understanding the gene pool is essential for studying Sources of Genetic Variation and how populations evolve over time.

Answer:

• A part of a chromosome that encodes an RNA or protein product in its DNA sequence
• All of the alleles of all the genes in a population (Correct answer)
• Forms of a gene with slightly different DNA sequences that may encode slightly different versions of the gene product
• The abundance of a particular allele among members of a population
