$A$ test cross of an unknown yellow seed with a green seed produces $50\%$ green seeds and $50\%$ yellow seeds. What is the genotype of the unknown yellow seed?

$A$ true-breeding plant producing red flowers is crossed with a pure plant producing white flowers. The allele for the red color of the flower is dominant. After selfing the plants of the first filial $(F_1)$ generation,what would be the proportion of plants producing white flowers in the progeny?

If two individuals with genotype $Bb$ are crossed and they produce two offspring,what is the probability that the second offspring will show the recessive trait,given that the first offspring shows the dominant trait?

In garden pea,round shape of seeds is dominant over wrinkled shape. $A$ pea plant heterozygous for round shape of seed is selfed and $1600$ seeds produced during the cross are subsequently germinated. How many seedlings would have the parental phenotype?

In Mendel's monohybrid cross experiment,the phenotypic ratio is $P$ and the genotypic ratio is $Q$. Select the correct option for $P$ and $Q$.
$\quad \quad \quad P \quad \quad \quad Q$

Show the phenotypic and genotypic ratios obtained from a Punnett square for a monohybrid cross.
