Question

    What term is used to describe the population that

    results from the sowing of hybrid seeds?
    A Homogeneous population of homozygous plants Correct Answer Incorrect Answer
    B Homogeneous population of heterozygous plants Correct Answer Incorrect Answer
    C Heterogeneous population of homozygous plants Correct Answer Incorrect Answer
    D Heterogeneous population of heterozygous plants Correct Answer Incorrect Answer
    E Heterogeneous population of both homozygous and heterozygous plants Correct Answer Incorrect Answer

    Solution

    Explanation: When hybrid seeds are sown (often from F1 hybrids), the resulting plants are typically heterozygous at most gene loci because they inherit different alleles from the two parent plants. The plants of the first generation (F1) are genetically uniform in terms of the cross, meaning they are mostly homogeneous with regard to their heterozygous genetic makeup. This population is considered homogeneous in the sense that all plants are hybrid and heterozygous, despite having a mix of genes compared to pure-breeding lines. Over subsequent generations, segregation occurs, leading to genetic diversity (heterogeneous population).
