Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (such as a sperm or egg cell) with a single set of chromosomes (haploid) combines with another to produce an organism composed of cells with two sets of chromosomes (diploid).
What is a sexual reproduction explain in short?
Sexual reproduction is a mode of reproduction involving the fusion of haploid female gamete (egg cell) and haploid male gamete (sperm cell). This is in contrast to asexual reproduction where an organism reproduces without involving gametes and the resulting offspring is a clone of the parent.27-Feb-2021
What is sexual reproduction Ncert?
Hint: Sexual reproduction is a mode of continuation of species involving the fusion of gametes from two sexes parents. That results in the formation of a zygote which eventually grows to become an individual similar to its parents. -Sexual reproduction is most commonly seen in humans, most animals, and some plants.
What is sexual reproduction answer in one sentence?
Reproduction in Plants | Exercise
What are the characteristics of sexual reproduction?
Features of Sexual Reproduction
Two parents are involved (both male and a female).
Gamete formation and fertilization take place.
The whole process is slow and lengthy.
The variation occurs; offspring are different from parents, genetically and physically.
Why is reproduction so important?
Reproduction is important for the survival of all living things. Without a mechanism for reproduction, life would come to an end. Asexual reproduction refers to simple cell division that produces an exact duplicate of an organism.
What are the advantages of sexual reproduction over asexual reproduction?
What are the advantages of sexual reproduction over asexual reproduction
What are the six characteristics of sexual reproduction?
It takes place with the help of gametes.
It is biparental in origin.
It is a slower method of reproduction.
Variations occur in sexual reproduction.
It is important for evolution.
It occurs more frequently in higher organisms than in prokaryotes.
What are the advantages of sexual reproduction?
The advantages of sexual reproduction:
produces genetic variation in the offspring.
the species can adapt to new environments due to variation, which gives them a survival advantage.
a disease is less likely to affect all the individuals in a population.
What are the features of reproduction?
In the reproduction process replication of the DNA occurs. The “growth and differentiation” of the cellular organelles. “Cell division of the zygote” occurs. In asexual reproduction exact copies are produced but sexual reproduction gives variation in their offspring.10-Feb-2018
What are 3 advantages of asexual reproduction?
What Are the Advantages of Asexual Reproduction
What are the advantages and disadvantages of asexual and sexual reproduction?
Asexual Reproduction Sexual Reproduction
Advantages Time Efficient; no need to search for mate, requires less energy Variation, Unique., organism is more protected
Disadvantages No variation – if the parent has a genetic disease, offspring does too. Requires two organisms, requires more energy

How are asexual and sexual reproduction similar?
Asexual reproduction yields genetically-identical organisms because an individual reproduces without another. In sexual reproduction, the genetic material of two individuals from the same species combines to produce genetically-different offspring; this ensures mixing of the gene pool of the species.
Is reproduction a life process?
Therefore reproduction is NOT an important life process because it is not necessary for the survival of a particular human being BUT it is necessary for the survival of the human species or a particular species. In short, reproduction IS indeed a life process.
What are two reproduction types?
There are two types of reproduction: asexual and sexual reproduction. Though asexual reproduction is faster and more energy efficient, sexual reproduction better promotes genetic diversity through new combinations of alleles during meiosis and fertilization.
What are two types of reproduction?
There are two types of reproduction Sexual and asexual reproduction.20-Mar-2019
Can a man get pregnant?
Yes, it’s possible for men to become pregnant and give birth to children of their own.20-Dec-2018
Can you have a baby without sperm?
Pregnancy without sperm — is it possible
How can I have a baby without a woman?
Men who are single, but want to pursue parenthood can choose a surrogate with an egg donor and become a father. This allows them to still have a biological connection to their children without having a partner. Single men can also choose embryo donation as an option to parenthood.
Why is animal reproduction important?
Reproductive success in livestock is essential for the economic livelihood of producers and ultimately affects the consumer cost of meat and other animal products. In many livestock production systems, poor fertility is a major factor that limits productivity.
What do you mean by vegetative reproduction?
Vegetative reproduction, any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or grows from a specialized reproductive structure (such as a stolon, rhizome, tuber, corm, or bulb).
