what is the difference between self pollination and cross pollination This is a topic that many people are looking for. newyorkcityvoices.org is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, newyorkcityvoices.org would like to introduce to you Self Pollination and Cross Pollination |Quick 5 min Differences & Comparisons|. Following along are instructions in the video below:
Lets discuss the differences between self pollination and cross pollination. So the first point point under self pollination is so for self pollination transfer of pollen grains from the to the stigma of the same flower occurs and for cross pollination. So for cross pollination transfer of pollen grains from the hand turn to the stigma of the different flowers occurs.
So now lets move on to the second point so for self pollination. This process can take place either in the same flower. Or another flower of the same plant and for cross pollination.
This process can take place between two flowers on different plants. Now lets move on to the third point. So self pollination occurs in the flowers.
Which are genetically same and for cross pollination so cross pollination occurs between flowers. Which are genetically different. So lets move on to the fourth point.
So the fourth point says that self pollination occurs only in perfect flowers and for cross pollination.
So cross pollination occurs both in perfect or imperfect flowers. Lets move on to the fifth point so self pollination causes homozygous condition in the progenies and cross pollination. They causes heterozygous conditions in the progenies.
So lets move on to the next point so self pollination increases genetic uniformity and decreases genetic variation and for cross pollination so cross pollination decreases genetic uniformity and increases genetic variation. So lets move on to the seventh point. So self pollination causes inbreeding and cross pollination causes.
So it causes out reading cross pollination causes out reading. So next. We have so self pollination reduces the gene pool and cross pollination.
So cross pollination. Maintains the gene pool. So the ninth point under self pollination.
Says that it produces limited amounts of pollen grains and for cross pollination.
So cross pollination produces large amounts of pollen grains. So in self pollination both the stigma and anther mature at the same time. But for cross pollination for cross pollination.
The stigma and then her mature at different time. So lets move on to the next point. So for self pollination a few number of pollen are transferred.
But for cross pollination. Large number of polands are transferred so lets move on so. The twelfth point says that this process is carried out even when the flowers are closed.
This is for self pollination and for cross pollination. So for cross pollination flowers should be open. So the last point under the self pollination says.
There no need of pollinators to transfer pollen grains and for cross pollination.
So require pollinators to transfer pollen. Grains. Pollen.
Grains are transferred to insects wind water and animals etc. So these were the differences between self pollination and cross pollination at last let us see a diagram which shows these two pollination techniques in details. So the self pollination diagram is shown here here the pollen grains marked as one are being transferred from the anther.
These are the anther from the anther to the stigma of the same flower. So hence. This is known as self pollination and for cross pollination.
So for cross pollination. You can see that the pollen grain moves from the anther of one flower to the stigma of another flower. This is a different flower this this one and this may be named as two so.
The pollen grains are being transferred from the stigma from the anchor of flour one to the stigma of the flower. So these were the differences between self pollination and cross pollination music. .
