Question

What is meant by dominant genes and recessive genes? Give one example of each.

Answer 1

• The gene which decides the appearance of an organism even in the presence of an alternative gene is known as the dominant gene.
• The gene which can decide the appearance of an organism only in the presence of another identical gene is called a recessive gene.
• Example, in pea plants, the dominant gene over recessive is T and the recessive gene is t. (Character : Plant height)
