In a particular plant species, the position of the flowers on the stem is controlled by a gene with two alleles. The allele coding for flowers growing in the middle of the stem (G) is dominant to the allele for flowers growing only at the end of the stem (g).
- Using the allele symbols, identify the genotype of a plant that is heterozygous for this trait.
- Draw a Punnett square to show the cross of two heterozygous plants.
- Using the cross in part (b), explain how heterozygous crosses demonstrate that alleles segregate. Be sure to describe the law of segregation in your answer.
- Identify the process that accomplishes segregation of alleles into sex cells.
