Variation mainly comes with sexual reproduction at three points.
1. Infidelity in DNA replication introduces variant alleles (mutant alleles)
2. Homologous recombination (crossover) exchanges alleles so new combinations appear in every generation.
3. Transposition (short tandem repeats as STR microsatellites; retrotransposed SINE & LINE regions

∙ 11y agogenetic effects is the effects on your genes when your body begins to change.
when you go through puberty, for example, your genes develop differently and alter permanentley. this is known as genetic effects stage 1.

Is Attention Deficit Disorder a genetic disorder?
It appears to be caused by a combination of genetic and environmental factors.
Is the character trait of integrity genetic or learned?
Mostly learned though as with all traits, nature and nurture are both factors in this attribute.
How do genetic and environmental factors work together to promote a child's temperament?
pretty much most of the genetic stuff could includ add and other genetic disabiliteis like that. But most of the things that cause tempermant issues are seeing how the parents behave and following example of kids and adults around them that they look up to.
What tends to increase genetic variation in a population?
Genetic variation is the total amount of genetic diversity present within a species or population. The amount of genetic variation in a population will depend on a variety of factors, including the size of the population, the type of reproduction, and environmental influences. The primary way to increase genetic variation in a population is through mutation. Mutations are random changes in the genetic code that can lead to new traits or characteristics. Mutations can be caused by environmental factors, such as exposure to radiation or chemicals, or they can occur spontaneously. Mutations can be beneficial, neutral, or detrimental to the organism, but they do lead to increased genetic variation. Another way to increase genetic variation in a population is through migration. When individuals from different populations mate, they bring with them different alleles from their home population, increasing the genetic diversity of the new population. This is especially important for populations that are geographically isolated, such as island populations. Another factor that can increase genetic variation is sexual selection. This is the process by which individuals select mates based on certain desired traits. This can lead to an increase in the number of different alleles in the population, as individuals with certain traits will be more likely to reproduce. Finally, gene flow is a process that can increase genetic variation in a population. Gene flow is when individuals from one population move to another population and mate with individuals in the new population. This can bring in alleles from the original population, increasing the genetic diversity of the new population. Overall, while mutation, migration, sexual selection, and gene flow are all important factors in increasing genetic variation in a population, it is important to note that genetic variation can also be decreased by inbreeding and genetic drift. Inbreeding is when individuals mate with close relatives, reducing the number of alleles in the population and leading to decreased genetic variation. Genetic drift is when random fluctuations in allele frequencies occur due to a small population size, leading to decreased genetic variation. Therefore, it is important to consider all of these factors when trying to increase genetic variation in a population.

Genetic factors, exposure to sunlight.
What genetic factors might be responsible for a change in an organism's body plan?
The importance of genetic factors has recently been at least halved by the discovery of Epigenetics.
Do genetic or environment factors cause cancer?
Genetic. If your mom had cancer you have a great risk of getting it too. You have, i dunno, genetic material.
