mutations of genes in an organism's sex cells & new combinations of existing genes during sexual reproduction.
Heritable characteristics are passed down from parents to offspring through genetic inheritance, while non-heritable characteristics are acquired through environmental factors or experiences. Examples of heritable characteristics include eye color and blood type, while non-heritable characteristics include skills acquired through education or behaviors learned through social interactions.
Events such as genetic mutations during DNA replication, genetic recombination during sexual reproduction, and exposure to environmental factors can result in offspring with unique heritable characteristics. These events can introduce new genetic variations that can be passed on to future generations.
Some characteristics like hair and eye colour, whether or not you can curl your tongue, your height, skin colour are all things that you inherit from your parents, also why you look like them. Other characteristics are not inherited, but could be a result of your surroundings. For example, fetal alcohol syndrom is not inherited from your mom, it is a result of your mom drinking when pregnant. Many birth defects in babies back in the 50's and 60's was a result of mothers taking thalidamide, a drug used to prevent morning sickness, a non-heritablecharacteristic!
Heritable variation refers to differences in traits among individuals that are passed down from one generation to the next through genetic inheritance. These variations are the result of differences in DNA sequences and can be influenced by factors such as mutations, recombination, and gene flow. Heritable variation is essential for natural selection to act upon, leading to evolution within a population.
yes, only heritable changes in the DNA come under the perview of mutation.

Genes are units of information about heritable traits. They are segments of DNA that code for specific proteins or RNA molecules, influencing various characteristics such as eye color, height, and susceptibility to diseases. Genes are inherited from parents and determine an individual's genetic makeup.
A heritable character or genetic character
Heritable variation refers to differences in traits or characteristics among individuals that are passed down from one generation to the next through genetic mechanisms. These variations are inherited from parents and contribute to the overall genetic diversity within a population.
Acquired characteristics are traits that an individual develops during its lifetime, such as a tan from sun exposure, and are not passed down to offspring. Adaptations are heritable traits that increase an organism's fitness in its environment and are passed down through generations. Acquired characteristics do not involve genetic changes, while adaptations are the result of genetic variation and natural selection.
