eye color, hair type, skin color, etc.
traits
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.
Quality traits, such as fat marbling and milk production are usually the most heritable. In general quality traits are more heritable than growth traits (such as weight), which are more heritable than reproductive traits (such as conception rate).
Characteristics passed down from parents to child. (eg. Blue eyes) Rather than traits learned from their environment (eg. learning to cycle) So definition= 'Heredity is the passing of traits from parents to offspring'
yes, only heritable changes in the DNA come under the perview of mutation.
Polygene : any of a group of genes that each produce a small quantitative effect on a particular characteristic of the phenotype, such as height. Oligogene :A gene dat produces/significantly affects da expression of a qualitative heritable characteristic,acting either alone or with a few other genes
Non heritable
For a characteristic to affect evolution, it must be heritable, meaning it can be passed down from one generation to the next. Additionally, the characteristic must influence the survival and reproductive success of individuals in a population. These two factors are essential for natural selection to operate and lead to evolutionary change.
A simple coevolution explanation here. A population of rabbits that is running faster, on average, over time is going to affect the population of foxes that pursue the rabbits as food. Some foxes will have variations that lead to faster running and these foxes will be the ones that are reproductively successful and give rise to following generations of foxes.
Non- Inherited characteristics are not developed at birth. You learn them in life for example: Riding a bicycle, using a computer, Liking a sport, adding and subtracting, to speak one or more languages. Hope this helps :)
HEritable information is a main theme connecting the concepts of biology together ebcause if there was no heritable information or DNA then there would be no life, and you need life to study biology, Bio - life ology - study of
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!
