Question

Which of the following statements is true?

Answer 1

2nd statement is true.

Explanation:

Chromosomes are made up of genes and a gene is made up of two copies of alleles. If an organism has two different types of alleles on its chromosomes then it's a hybrid organism else we call it a pure organism/trait.

1. Gene could be dominant or recessive.
2. A phenotype is the expression of a trait.
3. As 'tall' gene is considered to be dominant so so pea plant with even a single copy of 'tall' gene will have a tall phenotype.
