In most animals, the ______ state of the life cycle is much larger than the ______ state.
Alexxx [7]

In most animals, the diploid state of the life cycle is much larger than the haploid state.

<h3>What is life cycle?</h3>

The life cycle of animals is the oscillation of their lives between the haploid (n) or sexual phase and the diploid (2n) or vegetative phase.

The haploid or sexual phase of animals has to do with their gametes. The male animals produce male gametes while the female animals produce female gametes.

During fertilization, the haploid male gamete (n) fuses with the haploid female gamete (n) to form a diploid (2n) zygote. The zygote is what divides mitotically to form the baby and continues to divide to form the adult animal.

For example, in humans, the female gamete is the egg while the male gamete is the sperm. The diploid version of humans is what we see every day.

Thus, when you consider it, you will see that the haploid life cycle of most animals is much bigger than their diploid life cycle.

It is more beneficial to use plants for this process as compared to that of animals because it is easily available and easily extracted.

It is more economical and easily accessible by people. It would not harm animals by incorporating the gene in them in laboratory conditions.
