What is a cross between plants that involves one characteristic called
Monohybrid cross
Thank you
To understand the cross between plants that involves one characteristic, we first need to know some basic concepts. In the field of genetics, a characteristic is a specific observable feature or trait of an organism. It can be something like eye color, flower shape, or height.
The process of crossing plants to study or manipulate their characteristics is called plant breeding. Plant breeding aims to create new varieties or improve existing ones by combining desired traits from different plants.
One method used in plant breeding is called cross-pollination, where pollen from the flower of one plant is transferred to the stigma of another plant. This can be done manually or with the help of insects or wind.
Now, when you mention a cross between plants involving one characteristic, it suggests that breeders are interested in studying or manipulating a specific trait.
Here's a step-by-step explanation of how a cross between plants with one characteristic works:
1. Identify the characteristic: Choose the characteristic you want to study or manipulate. For example, let's consider plant height.
2. Select parental plants: Choose two plants with different heights. One can be a tall plant, while the other can be a short plant.
3. Cross-pollination: Transfer pollen from the flower of the tall plant to the stigma of the short plant. This can be done by removing the male stamen from the tall plant's flower and gently rubbing it on the stigma of the short plant's flower.
4. Let fertilization occur: After cross-pollination, fertilization takes place, resulting in the production of seeds.
5. Collect seeds: Allow the seeds to develop and mature on the short plant.
6. Plant the seeds: Collect the mature seeds and plant them in a suitable environment (soil, sunlight, water, etc.) for germination.
7. Observe the offspring: As the offspring plants grow, observe their heights. Some will be tall, while others will be short.
8. Analyze the data: Compare the heights of the offspring plants to determine if there is a pattern or correlation. This analysis will help you understand how the chosen characteristic is inherited and how it might be manipulated in future generations.
So, to summarize, a cross between plants involving one characteristic involves selecting plants with different traits, cross-pollinating them, collecting and planting the resulting seeds, and analyzing the offspring to study and manipulate the desired characteristic.
