    The ratio of yellow seed phenotype with green seed color seed offsprings will be 4:0.

    Explanation:

    Given that:

    Dominant trait is Y (yellow seed color)

    recessive trait is y (green seeds color)

    cross between YY and yy, According Mendelian Genetics dominant trait will be seen in phenotype as it masks the effect of recessive gene.

    Punnet square shows that:

    Y Y

    y Yy Yy

    y Yy Yy

    All the plants produced will be tall phenotype.

    The yellow seed plant plants will be heterozygous i. e Yy

    the phenotype ratio is 4:0

    The genotype ratio is 4:0

    The genotype of the offspring is Yy

    phenotype is yellow colored seed plant.
