How did Mendel cross pollinate pea plants?
by emasculation and hand pollination
Why is cross-pollination rare among pea plants?
Cross-pollination is rare among pea plants primarily due to their structure and reproductive mechanisms. Pea plants are predominantly self-pollinating, as their flowers have both male and female reproductive organs, allowing them to fertilize themselves. Additionally, the flowers are often closed, which further limits the opportunity for cross-pollination. Environmental factors and the absence of pollinators also contribute to the prevalence of self-fertilization in these plants.
How do peanut plants reproduce?
Plants that do not require external help to transfer their pollen are known as self-pollinating plants. Peanuts belong to this category and reproduce by dropping old flowers to the ground on growing old. These flowers release their pollen at sunrise and start fertilizing eventually.
How did gregor mendel sex his pea plants?
Gregor Mendel used a paintbrush to transfer pollen from the stamen of one pea plant to the pistil of another, enabling controlled cross-pollination. He also used self-pollination techniques when studying pea plant traits.
Why did Gregor Mendel not pollinate the first generation pea plants?
Mendel allowed the offspring of his experimental plants to self-pollinate. That is, he allowed the male and female reproductive cells of the same plant to join and produce a seed. One of the characteristics of pea plants is that it is easy to cross different pea plants but, left to themselves, they self-pollinate with little chance of any accidental pollination between plants.

What are the two methods of sexual reproduction Used by pea plant?
Cross-pollination and Self-pollination are the two methods used by pea plants in sexual reproduction
What kind of plants did Gregor Johann Mendel work with and why?
Gregor Mendel used pea plants in his experiments to study heredity

What are the example cross pollination?
Examples of cross pollination include bees transferring pollen from one flower to another, wind carrying pollen from one plant to another, and human intervention in manually transferring pollen between plants.

What would happen if you cross pollinate pea plants?
You get pea plants.
Can pollination in pea plants happen in three ways?
Pea flowers are self-pollinating. About two days before the flower even opens, the anthers at the top of the stamen, which are the male part, burst and release the pollen. This sticks onto the stigma and fertilizes the ovary - these are the female parts. In many flowering plants, the stigma will not accept pollen from the same plant and fertilization must occur through other means, such as insect pollination after the flower opens. For gardeners, self-pollination is an advantage as it means more than one type of pea can be grown close together, as cross-pollination will not occur.
Why did mendel remove the anthers from the pea plants when performing cross-pollination in his experiment?
Mendel removed the anthers from the pea plants to prevent self-pollination, as he wanted to control the pollen used for cross-pollination. By removing the anthers, he could ensure that only the desired pollen was used to fertilize the pistil of the plant. This allowed Mendel to accurately study the inheritance patterns of specific traits in his experiments.
The cross between the pea plants yielded 78 pea plants with axial flower position and 80 pea plants with terminal flower position What are the genotypes of the pea plants involved in the cross?

Describe gregor mendels experiment with pea plants?
Gregor Mendel's pea plant experiment allowed him great control, as pea plants can self-pollinate or cross-pollinate, and he was able to pollinate them at will. He studied the characteristics of each plant he would cross-pollinate, perform the pollination and plant the resulting seeds, then study the characteristics of the resulting plants.
