In a monohybrid cross,$120$ plants are obtained. The ratio of homozygous and heterozygous individuals shall be:

If enough crosses are made between male flies of the genotype $Aa$ and female flies of the genotype $aa$ to produce about $1000$ offspring,which one of the following is the most likely distribution of genotypes in the offspring?

If a tall plant is crossed with a dwarf plant and the obtained progeny is half tall and half dwarf plants,then the genotype of the parents will be:
