To determine which statements are correct examples of a genotype, we need to understand that a genotype refers to the genetic constitution of an organism—essentially, the specific alleles or versions of a gene that an organism possesses.

Here are the statements evaluated:

  1. The flower has red pigment gene and a copy of the white pigment gene: This is an example of a genotype, as it specifies the different alleles (red and white pigment genes) present in the flower.

  2. The tree produces red fruit: This statement describes a phenotype (the observable characteristic) rather than a genotype, as it does not specify the underlying genetic makeup.

  3. The cheetah has two copies of the gene that causes stronger muscles: This is an example of a genotype, as it indicates the presence of specific alleles related to muscle strength.

  4. The blue jay has shorter wings: Similar to statement 2, this describes a phenotype (the observable characteristic of shorter wings) without specifying the genetic makeup.

Based on the above evaluations, the correct examples of a genotype are:

  • The flower has red pigment gene and a copy of the white pigment gene
  • The cheetah has two copies of the gene that causes stronger muscles
