Important Questions on Heredity

EASY
If a round, green seeded pea plant (RRyy) is crossed with wrinkled, yellow seeded pea plant (rrYY) the seeds produced in F1 generation are :
EASY
When a tall plant with round seeds was hybridized with a dwarf plant with wrinkled seeds; all offspring in F1 generation were tall plants that produced round seeds. As per Mendel’s law of independent assortement, what percent of offspring will produce wrinkled seeds if F1 is crossed with tall plant producing wrinkled seeds?
EASY
A plant with red coloured flowers is crossed with a plant having white flowers. The red and white colour of the flower is controlled by a single gene. Red is dominant over white. The F1 progeny is self-pollinated and the flower colour in F2 is observed. Given the above information, what is the expected phenotypic ratio of plants with different flower colours?
EASY

A round green (RRyy) seed plant is crossed with a wrinkled yellow (rrYY) seed plant. According to Mendel’s law the phenotypic ratio in F2 generation will be
