Answer 2

Hybridization and photoperiod:

Hybridization:

• It is a process of crossing between dissimilar organisms / same varieties to get a desired trait progeny.

• It results in the production of hybrids.
• It brings out the variation among the plant/animal group.

Benefits of Hybridization

1. increases the yield of plants
2. gives rise to resistant plants
3. produces organisms with selected qualities.

Photoperiod:

• The duration of time that a plant/animal is exposed to the light in a day.

• It is important in plants because the food synthesis method called photosynthesis depends on light.

• Short photoperiod results in the plant growth retardation.
