    The sweet pea plant has been used to study inheritance since the nineteenth century. The seeds of the sweet pea can vary in colour and shape.''

    The gene that controls colour has two alleles:
    - Y is dominant and produces yellow seeds
    - y is recessive and produces green seeds

    The gene that controls shape has two alleles:
    - R is dominant ad produces round seeds
    - r is recessive and produces wrinkled seeds
    A) In the nineteenth century, Gregory Mendel crossed a pea plant that was heterozygous for both seed colour and shape with a pea plant that had green and wrinkled seeds.
    ( I) List the gametes that would be produced by a sweet pea plant that was heterozygous for both seed colour and shape.

    (ii) List the genotypes off the offsprings that were produced from Mendel's cross and state the corresponding phenotypes.

    You posted the same thing thrice.

    For part (ii), write the gametes for the pea plant that had green and wrinkled seeds. Using the answer to part (i), you can draw a Punett Square to get the genotypes and the corresponding phenotypes.

    Gametes: YR, Yr, yR, yr
    Genotype: make a punnet square you get a ratio of 9:3:3:1
