In cotton genetic male sterility is governed by recessive gene. It is transferred by back cross method of conventional plant breeding. After each backcross F1 is selfed to raise the F2 population in which you will get 50% fertile & 50% sterile population. Generally 5-6 backcrosses are needed.

Which tube is cut to produce sterility in the male?
The vas deferens is cut in a procedure called a vasectomy in order to produce sterility in males. This prevents sperm from being released during ejaculation.
What two things does pollen get from the anther to the stigma?
Pollen carries male gametes from the anther to the stigma during pollination. This process enables fertilization in plants, facilitating the transfer of genetic material between the male and female reproductive structures.
Why does sexual reproduction need a male and female?
Sexual reproduction requires a male and female because it combines genetic material from two individuals, leading to genetic diversity in offspring. This genetic diversity promotes adaptability and survival of species in changing environments. The male provides sperm containing genetic material, while the female provides eggs containing genetic material and a nourishing environment for the embryo to develop.
Is a male with XXY chromosome combination a normal male or sterile male?
A male with XXY chromosome combination has a condition called Klinefelter syndrome. This can lead to reduced fertility, but not complete sterility. These individuals can father children with assisted reproductive technologies.
What is it called when mutations in the CFTR gene affect water and mineral transport throughout the body leading to male sterility thick mucus in the lungs and salty sweat?
It is called Pleiotropy.
What is male sterility in plant?
Male sterility in plants refers to the condition where a plant is unable to produce functional pollen, either due to genetic abnormalities or environmental factors. This results in the plant being unable to undergo successful fertilization and produce seeds. Male sterility is often used in plant breeding to facilitate hybrid seed production.
Can tobasco on the testes cause male sterility?
No it will not.
Why do some flowers fail to have fruits or seeds?
Due to male or female sterility
What causes men to be steril?
Male sterility can be caused by various factors, including genetic abnormalities, hormonal imbalances, and medical conditions such as diabetes or infections. Environmental factors, such as exposure to toxins or radiation, can also play a role. Additionally, lifestyle choices like smoking, excessive alcohol consumption, and obesity may negatively impact sperm production and quality. In some cases, the cause of male sterility remains unexplained.
What has the author Richard D Amelar written?
Richard D. Amelar has written: 'Male infertility' -- subject(s): Male Infertility, Male Sterility
Example of hybrid sterility?
One example of hybrid sterility is the mule, which is a hybrid offspring of a male donkey and a female horse. Mules are typically sterile because they often inherit an uneven number of chromosomes from each parent, leading to difficulties in the production of viable gametes. This genetic incompatibility results in the mule's inability to reproduce.
Which tube is cut to produce sterility in the male?
The vas deferens is cut in a procedure called a vasectomy in order to produce sterility in males. This prevents sperm from being released during ejaculation.
Are there lingering after-effects from malaria after you've been cured?
Depending upon how high temperature was for duration male sterility is a long term effect related to the killing off of sperm. The sterility can last for many years or be permanent.
What two things does pollen get from the anther to the stigma?
Pollen carries male gametes from the anther to the stigma during pollination. This process enables fertilization in plants, facilitating the transfer of genetic material between the male and female reproductive structures.
Why are figs good for you?
Figs are full of seeds and hang in twos when they grow. Figs increase the mobility of male sperm and increase the numbers of Sperm as well to overcome male sterility.
How can zucchini be pollinated effectively in the absence of male flowers?
Zucchini can be pollinated effectively in the absence of male flowers by using a small brush or cotton swab to transfer pollen from the male flowers of another zucchini plant onto the female flowers of the plant without male flowers. This manual pollination method can help ensure successful fruit development.
What is the difference between impotence and sterility?
Impotence is the inability of a male to perform the act of intercourse, through either mental, or most likely, biological means. Sterility is the lack of enough viable sperm to impregnate the female. Sterile males usually can perform intercourse, however.
