Parent AA and Parent aa have children. All children are Aa
Parent Aa and Parent Aa have children. 1AA:2Aa:1aa probability with each child.
This is recombination of the most direct/simplest kind.
It would be wrong to consider mitosis insignificant as it helps in cell repair and replacement in our daily life and it would be impossible to survive without it and asexual reproduction as well but if it weren't for meiosis, none of us would have been born :) Meiosis is responsible for the division for our gamete cells which leads to the formation a zygote. from there on mitosis takes over.
nondisjunction
frameshift mutation: deletion
Occurs during prophase I of meiosis (pachytene) in a process called synapsis. Crossover usually occurs when matching regions on matchingchromosomes break and then reconnect to the other chromosome. The value of crossing over is that each parent has a different daughter cell.
i believe it is crossing over
Asexual reproduction results in identical offspring unless mutation or genetic recombination occurs, introducing variation among the offspring.
Sexual reproduction produces genetic variation through the recombination of genetic material from two parent organisms, while asexual reproduction typically results in offspring that are genetically identical to the parent. This variation generated through sexual reproduction allows for the potential for increased diversity and adaptation within a population.
Genetic recombination in paramecium can occur during conjugation, where genetic material is exchanged between two individuals. This process of recombination is separate from population growth, which occurs through asexual reproduction (binary fission) where a single cell divides into two identical daughter cells.
Offspring from sexual reproduction are genetically unique due to genetic recombination from the mixing of genetic material from two parents. This results in offspring who vary in their genetic makeup, which can lead to differences in physical traits and characteristics among siblings.
Asexual reproduction, such as binary fission or budding, leads to offspring with exact copies of their parents' genotypes. This is because there is no genetic recombination involved in asexual reproduction, thus resulting in identical genetic material being passed down to the offspring.
Common challenges faced when dealing with recombination frequency problems in genetic studies include the complexity of genetic interactions, the difficulty in accurately measuring recombination events, and the potential for errors in data analysis leading to inaccurate results.
Natural selection has favored sexually reproducing organisms because this process provides more genetic variation than asexual reproduction. Populations that are variable are more likely to have individuals that possess the necessary genes to meet environmental changes. In sexual reproduction a new Organism results when the recombination of a male haploid/gametic Sperm Cell genetic complement occurs with a female haploid/gametic Ovum genetic complement. A viable, and usually fertile, zygote ensues. You ask When, I say it is that moment of recombination. [What could be more clear?]

Genetic recombination is the process by which two DNA molecules exchange genetic information. This process results in the production of a new combination of alleles.

DNA recombination refers to the phenomenon whereby two parental strands of DNA are tied together resulting in an exchange of portions of their respective strands. DNA recombination results in the process leads to new molecules of DNA that contain a mix of genetic information from each parental strand. There are 3 main forms of genetic recombination. i. Homologous recombination ii. Site-specific recombination iii. Transposition www.examville.com
Recombination and independent assortment during meiosis contribute to genetic diversity by shuffling and mixing genetic material from two parents. Recombination creates new combinations of genes on chromosomes, while independent assortment randomly distributes these chromosomes into gametes. This results in a wide variety of genetic combinations in offspring, increasing genetic diversity.
