In pea plant the gene for yellow seed colour is dominant over green and round seed shape is dominant over wrinkled. Write the four types of gametes formed in a heterozygous pea plant with yellow and round seeds. (Yy Rr).

In One of his dihybrid crosses, Mendel crossed a true breeding double dominant pea plant with round and yellow seeds with true breeding double recessive plant having wrinkled and green seeds. The phenotypic ratio got was 9:3:3:1. Using checker board], try to find out the genotypic ratio.

Write the genotypic symbols for the following phenotypic characters, dominant homozygous round yellow seeded male, recessive wrinkled green seeded female and their possible gametes from both parents.

To find out the unknown genotype of a violet flowered pea plant a researcher done the following cross. Observe the diagram and answer the questions. (Hint: Violet flower colour in pea plant is dominant over white) Can you determine the unknown genotype of violet flowered parent by drawing Punnet square?
