The ratio of cross between the two heterozygous tomato plants is 9:3:3:1

A cross was performed between two parent plants of unknown genotypes. The offspring were segregated based on two flower characteristics i.e. flower colour [magenta $\left(\mathrm{M}\right)$ or white] and flower position [axillary $\left(\mathrm{A}\right)$ or terminal] and counted. The two genes responsible for these characters are not linked and segregate independently. Based on the information given in the table, predict the genotypes of the parents.

A round seeded tall pea plant is crossed with round seeded dwarf plant and obtained progeny are with following phenotypes
$3$ - Tall, Round
$3$ - Dwarf, Round
$1$ - Tall, Wrinkled
$1$ - Dwarf, Wrinkled

The possible genotype of parents:

If homozygous tall plant bearing red flowers is crossed with a homozygous dwarf plant bearing white flowers. What will be the genotype and phenotype of the first filial generation?

A pure tall plant bearing red colour flowers was crossed with a pure dwarf plant with white flowers,
(i) What would be the nature of offspring in the F1 generation?
(ii) If the offspring of the F1 generation are self-pollinated, what would be the ratio of red flowers to white flowers in the F2 generation?
(iii) What can you infer from the ratio obtained? Which law does it illustrate?
