List of top Biology Questions on Dihybrid Cross

In a trihybrid cross involving three different genes (\( AaBbCc \times AaBbCc \)), what is the expected genotypic ratio among the offspring?

In dihybrid cross, when F1 plants (RrYy) are self hybridised, the ratio of segregation of yellow and green in F2 is :

A colour blind man marry with a daughter of colour blind father, the generation will be

A common test to find the genotype of a hybrid is

In a given plant, red colour $(R)$ of fruits is dominant over white fruit $(r)$ : and tallness $(T)$ is dominant over dwarfness (t). If a plant with genotype $RRTt$ is crossed with a plant of genotype $rrtt$, what will be the percentage of tall plants with red fruits in the next generation?

If a plant having yellow or round seeds was crossed with another plant having green and wrinkled seeds then $F_1$ progeny are in the ratio:
