It is a result of genetic recombination leading to a combination of genetic information from each parent. This process leads to genetic diversity and variation in offspring.
Variation results from the combination of genetic material from the sperm and egg during fertilization. Each sperm and egg carries a unique set of genes, leading to genetic diversity in the offspring. This genetic variation is important for evolution and adaptation in a population.
Variation is important because it produces species with different gene combinations which result in the new offspring to become more immune to other dieseases.
In prophase of meiosis, first, a stage comes (known as crossing over) in which homologous chromosomes, after pairing, exchagne their genetic material. This is the stage where varition occurs during, and only in, meiosis I.
Variation in a new generation is the result of a combination of genetic factors inherited from the parents, as well as random mutations that occur during the process of DNA replication. These variations contribute to the diversity seen within a population and are essential for natural selection and evolution.
It is a result of genetic recombination leading to a combination of genetic information from each parent. This process leads to genetic diversity and variation in offspring.
Variation in the offspring of sexually reproducing organisms is the direct result of genetic recombination during the formation of gametes (sperm and egg) and the random mixing of genetic material from the two parents. This process increases genetic diversity within a population, allowing for adaptation to changing environments and evolution over time.

Variation results from the combination of genetic material from the sperm and egg during fertilization. Each sperm and egg carries a unique set of genes, leading to genetic diversity in the offspring. This genetic variation is important for evolution and adaptation in a population.
Crossing over during meiosis creates genetic variation by exchanging genetic material between homologous chromosomes, leading to new combinations of genes in offspring. This increases genetic diversity and can result in unique traits in individuals.
Sexual reproduction leads to variety in offspring.

Offspring that result from meiosis and fertilization inherit half of their genetic information from each parent. This process ensures genetic diversity and variation in the offspring. Meiosis is responsible for producing gametes with half the number of chromosomes, while fertilization combines the genetic material from two parents to create a unique individual.
Germinal variation is the type of variation that occurs only in germplasm of organisms.so,only the variations from the germplasm and the gametes are passed on the offsprings.It may be apparent from the birth of the individual or may develop at any stage of life of the organism. By,M.J.G.
Healthier offspring with more variation of their genes, which means that there are a wider variety of the differing alleles. Another result is that the offspring may have favourable characteristics (in the case of evolution) and also they could be more adaptable to the environment if it were changing.
Variation of offspring in sexually reproducing organisms is mainly due to genetic recombination during meiosis, which leads to unique combinations of genetic material being passed on to offspring from their parents. Additionally, mutations can also contribute to variation by introducing new alleles into the gene pool.
