Mendel's principle of segregation was based on the separation of alleles in the garden pea during

Self pollination between $Tt$ and $Tt$ plants results into genotype ratio of

The crossing of a homozygous tall plant with a dwarf in $F2$ would yield plants in the ratio of

Mendel crossed a pure white-flowered recessive pea plant with a dominant pure red-flowered plant. The first generation of hybrids from the cross should show

In a monohybrid cross of plants with red and white flowered plants, Mendel got only red flowered plants. On self-pollinating these $F_1$ plants got both red and white flowered plants in $3:1$ ratio. Explain the basis of using $RR$ and $rr$  symbols to represent the geno type of plants of parental generation.

If enough crosses are made between male flies of the genotype $'Aa'$ and the female flies of the genotype $'aa'$ to produce about $1000$ offsprings. Which one of the following is the most likely distribution of genotypes in the offsprings
