In pea plants, the colour of the flower is either violet of white whereas human skin colour shows many gradations. Explain giving reasons how it is possible.

Assertion: A geneticist crossed a pea plant having violet flowers with a pea plant with white flowers, he got all violet flowers in first generation. Reason: White colour gene is not passed on to next generation.

In humans, height and skin colour shows a lot of variation. They are example of

A cross between a red flower bearing plant and a white flower bearing plant of Antirrhinum produced all plants having pink flowers. Work out a cross to explain how this is possible.

In garden pea plant, the gene responsible for flower colour also affected the shape of the leaves and the colour of the seed coat. The phenomenon responsible for this is

A plan with red coloured folowers is crossed with a plant having white fllowes. The red and white colour of the flower is controlled by a single gene. Red is domainan 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 ?

A pea plant parent having violet coloured flowers with unknown genotype was a plant having white coloured flowers in the progeny 50% of the flowers were violet and 50% were white. The genotype constitution of the parent having violet coloured flower was:

How many colours does white light consist of and what are they?

In swseeet Pea , the flower colour changes from Red to white and seed coat colour from grey to white. This is an example of
