<h2>
2nd statement is true.</h2>
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.
- Gene could be dominant or recessive.
- A phenotype is the expression of a trait.
- 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.
In both animals and plants, cells produce new cells by mitosis - but they split differently. A cleavage farrow forms in the animal cell and it splits. For the plant cell, a cell plate forms and then the cell splits.
