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?

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?

In meiosis, each of the four daughter cells have one set of chromosomes. Due to the randomness of the process of chromosome separation in meiosis, a larger number of chromosome combinations can form gametes. How many such chromosome combinations in the gametes are possible in case of humans, assuming there is no crossing-over taking place?

In a Mendelian experiment tall pea plant bearing violet flowers was crossed with short pea plants bearing white flower. All the progeny had violet flowers, but almost half of them were short in height. The genetic make-up of the tall parents can be depicted as.
