In asexual reproduction new plants are obtained without production of seeds or spores.
Vegetative propagation
It is a type of asexual reproduction in which new plants are produced from roots, stems, leaves and buds. Since reproduction is through the vegetative parts of the plant, it is known as vegetative propagation.
2. Budding
-
Yeast is an organism that contains a single cell. It is a fungi not a plant.
-
It can propagate every few hours if the proper amount of nutrients are available to it.
-
As the yeast finds favourable conditions, a small bulb-like projection produces from the yeast called Bud.
-
The bud grows gradually and then gets detached from the parent yeast.
-
This new cell then grows measures and produces more cells.
3. Fragmentation
-
Algae like Spirogyra generally reproduce by the process of fragmentation in which they divide themselves into multiple parts.
-
As soon as the algae find enough water and nutrients, it fragments and grows into new individuals.
-
This process continues and algae multiply quickly in a short period of time.
4. Spore Formation
-
Some plants contain spores that float in the air and cause asexual reproduction.
-
A spore has a hard protective cover which protects it from the unfavourable environmental conditions like temperature and humidity.
-
As a result, the spores can travel long distances and survive for a long duration of time.
-
As soon as they find favourable conditions such as moisture and nutrients, they germinate and form new plants.
-
For Example, Moss and ferns propagate in this way.

The branch of horticulture that deals with the study of fruits and practice of their cultivation is called pomology.
Pomology refers to the science of fruit growing. It is the branch of botany that studies and cultivates fruit. Pomological research is mainly focussed on the development, cultivation and physiological studies of fruit trees.
Studies include enhancement of fruit quality, regulation of production periods, and reduction and production cost.

The distance between two consecutive base pairs in a double helix DNA is 0.34 X 10−9m.
The total length of double helix DNA in an organism can be calculated by multiplying the total number of base pairs with distance between two consecutive base pairs
Total length of double helix DNA = total number of base pairs X distance between two consecutive bp
1.36mm = x X 0.34 X 10−9m
by solving this we get, x = 4 X 106bp
So the number o base pairs in a DNA of E.Coli o 1.36mn is 4 X106 bp

Complete dominance is a form of dominance in heterozygous condition wherein the allele that is regarded as dominant completely masks the effect of the allele that is recessive. For instance, an individual carrying two alleles that are both dominant (e.g. AA), the trait that they represent will be expressed. Co-dominance and Incomplete Dominance. In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

Testicles form in the abdomen during fetal development. During the last couple of months of normal fetal development, the testicles gradually descend from the abdomen through a tube-like passageway in the groin (inguinal canal) into the *******. With an undescended testicle, that process stops or is delayed.

The first step in rDNA technology is to isolate the desired DNA in its pure form i.e. free from other macromolecules. ... Other macromolecules are removable with other enzymes or treatments. Ultimately, the addition of ethanol causes the DNA to precipitate out as fine threads. This is then spooled out to give purified DNA. Recombinant DNA technology. This technology has five steps: (1) cutting the desired DNA by restriction sites, (2) amplifying the gene copies by PCR, (3) inserting the genes into the vectors, (4) transferring the vectors into host organism, and (5) obtaining the products of recombinant genes.

Females have two X chromosomes. The somatic cells of females are not involved in sexual reproduction. Here one of the two X chromosomes is inactivated by lyonization. This inactive X chromosome is known as a Barr body.
The process of X-inactivation was discovered by Mary F. Lyon, a British geneticist. One X-chromosome is inactivated so that unnecessary information is not passed onto the next generation. The amount of expression of X-chromosome genes should be equal in both males and females.

Medical Definition of Lymphocyte
Lymphocytes: A small white blood cell (leukocyte) that plays a large role in defending the body against disease. Lymphocytes are responsible for immune responses. There are two main types of lymphocytes: B cells and T cells.

Nobel laureate Norman E.Borlaug, at International Centre for Wheat and Maize Improvement in Mexico, developed semi-dwarf wheat.
In 1963, several varieties such as Sonalika and Kalyan Sona, which were high yielding and resistant, were introduced all over the wheat-growing belts of India.

Erythroblastosis fetalis refers to life-threatening disease of a fetus or a new born infant in which the immune system of the mother produces antibodies against the red blood cells of the infant resulting in the destruction of the red blood cells of the fetus. This is because of the Rh incompatibility between the mother and the fetus and may result the fetus to suffer from severe anaemia, brain damage or even death in extreme cases.
