Which statement best explains the significance of meiosis in the process of evolution within species?
Meiosis takes place in sexual reproduction and genetic variations takes place in sexual reproduction. Genetic variations lead to evolution to new species. ...
Explain the cause of differences in number of cell and chromosomes after mitosis and meiosis?
Mitosis is single cellular reproduction, whereas meiosis is sexual cellular reproduction (between gametes). Thus, mitosis does not change the number of chromosomes, but meiosis doubles the original number. ...

What is the biological significance of meiosis?
Sexual reproduction- it ensures the production of haploid gametes in sexual reproduction. Genetic Variation- Meiosis provides opportunity for new combination of gametes to occur in the gametes. This leads to genetic variation in the offspring produced by fusion of the gametes. It also allows trait inheritance in offsprings ...

The most significant characteristic of sexual reproduction is?
The most significant characteristic of sexual reproduction is genetic variability. Variation produced by sexual reproduction starts during meiosis. ...
Asked in Genetics
Is Meiosis the process by which gametes are formed so sexual reproduction can take place?
Meiosis is the process by which gametes are formed so sexual reproduction can take place. The process of meiosis also increases genetic variation in the population. ...
Asked in Genetics
Does asexual reproduction contribute to sexual variation?
Asexual reproduction does not contribute in sexual variation because no meiosis is involved in asexual reproduction which is basic source of variation . Perpetual asexual reproduction can contribute to sexual variation due to mutations. ...
