Describe how Mendel cross pollinated pea plants?
Gregor Mendel cross-pollinated pea plants by manually transferring pollen from the stamen of one pea plant to the pistil of another pea plant. He carefully removed the anthers from the first plant to prevent self-pollination and then applied the pollen to the stigma of the second plant. This process allowed Mendel to control the genetic makeup of the offspring and study the inheritance patterns of specific traits in pea plants.
Pea plants usually produce seeds through?
self-pollination
Why mendel selected pea plant to study?
maybe he was lucky and he did so without knowing the reason but today we know the pea plant is 2n=14. so it has 7 pairs of chromosomes. if mendel had studied 8 traits for example, then at least 2 of them would've been on the same chromosome and he couldn't have used its mathematical laws of independence because then at least 2 chromosomes were linked.
Do zooplankton make their own food?
A ZooPlankton Eats Anything , But It Has To Be Smaller Than Its Self .
How can a new plant be different from its parent plant?
No. While the new plants will look similar to the parent plants, seeds are the result of assexual reproduction and assexual reproduction means that the offspring are all unique. In other words there will be variation in exactly the same way as children do not look exactly the same as their parents.
What result did mendel get when he allowed the first-generation plants to self-pollinate?
Gregor Mendel developed the model of heredity that now bears his name by experiments on various charactersitics of pea plants: height (tall vs. Short); seed color (yellow vs. Green); seat coat (smooth vs. wrinkled), etc. The following explanation uses the tall/short trait. The other traits Mendel studied can be substituted for tall and short.Mendel started out with plants that "bred true". That is, when tall plants were self-pollinated (or cross-pollinated with others like them), plants in following generations were all tall; when the short plants were self-pollinated (or cross- pollinated with others like them) the plants in following generations were all short.Mendel found that if true breeding Tall [T] plants are crossed (bred) with true breeding short [t] plants, all the next generation of plants, called F1, are all tall.Next, he showed that self-pollinated F1 plants (or cross- pollinated with other F1 plants) produce an F2 generation with 3/4 of the plants tall and 1/4 short.A. 1/4 of the F2 generation are short plants, which produce only short plants in the F3 generation, if they are self- pollinated (or crossed with other short F2 plants;) these F2 plants breed true.B, 1/4 of the F2 generation (1/3 of the tall plants) are tall plants that produce only tall plants in the F3 generation, if they are self-pollinated; these tall F2 plants breed true.C. 1/2 of the F2 generation (2/3 of the tall plants) are tall plants that produce 1/4 short plants and 3/4 tall plants in the next [F3] generation, if they are self-pollinated. This is the same proportion of tall to short that F1 plants produce.
Is anther above stigma in self pollinated plants?
Yes

What was mendels second experiments?
Mendel allowed the first generation plants to self pollinate.
Are all self pollinated plants are self fertilized plant?
No, all self-pollinated plants are not necessarily self-fertilized. Self-pollination refers to the transfer of pollen from the anther to the stigma of the same flower or a different flower on the same plant, while self-fertilization involves the fusion of sperm and egg cells from the same plant. Some self-pollinated plants can still receive pollen from other plants and undergo outcrossing, leading to genetic diversity.
Step 1 of Mendel's garden pea experiments allowing each variety of garden pea to self pollinate for several generations produced which generation?
Mendel found that every fourth plant had white flowers when he allowed the first generation to self-pollinate. Gregor Mendel was a scientist who lived from 1822 to 1884.hyuyt6yt8
Why hybrids are not successful in self pollinated crops?
In self pollinated crops, hybrid vigour is not just like the cross pollinated crop e.g maize.cross pollination in self pollinated crop produce low seed set and cost of hybrid seed increases.less cytoplasmic male sterility and fertility restorer gene in mostly self pollinated crop.
Which organ mature first in self pollinated plants the male or female?
male
Is a sampaguita self or cross pollinated?
self pollinated
What did Mendel do to make sure the plants in his experiments cross pollinated and did not self pollinate?
he used plants that were NOT true breeding!
Which plant organ mature first in self pollinated plants the male or female?
male
How do the sunflowers become pollinated?
they are self-pollinated!!
