In your garden you have a pea plant with purple flowers (which you know is dominant to white flowers according to Mendel's observations). To determine the genotype of your pea plant, you perform a testcross and obtain the progeny listed in the table. Phenotype Purple flowers White flowers Number of plants Based on the data, which of the following is the genotype of your pea plant? a. Heterozygous b. Homozygous recessive c. Homozygous dominant d. Cannot be determined from the data given

Explanation / Answer

12) During meiosis diploid number of chromosomes is converted to haploid number of chromosomes. If there is a non disjunction of chromosomes during meiosis, one daughter cell will have extra chromosome and the other daughter cell will have lesser number of chromosomes. So, if the non disjunction occurs during meiosis with diploid number of 10 chromosomes, half of the daughter cells will have 6 chromosomes and the other half will have 4 chromosomes. (Option d).
