What is heritable variation?
Heritable variation is the variation in characteristics caused by genetic factors.
Units of information about heritable traits?
A gene is a unit that determines heritable characteristics. An allele is one of the alternative versions of a gene for a character.
Do all mutations result in heritable changes?
yes, only heritable changes in the DNA come under the perview of mutation.
A heritable change in the characteristics within a population from one generation to the next?
Evolution.
What is the term used to describe the heritable physical characteristics of living organisms?
phenotype
What is the term used to describe the heritable physical characteristics of living organism?
phenotype
What is the term used to describe the heritable physical characteristics of a living organisms?
phenotype
Which events can result in an offspring with unique heritable characteristics?
recombination of existing genes during sexual reproduction and mutations of genes in an organism's sex cells... someones cheating on study island XD ;)
What does heritable variation mean?
Inherited variation is when we inherit half of our characteristics from each parent.
Difference between heritable and non heritable variation?
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!
What do you call a change of the DNA in an organism that result in a new trait?
A heritable character or genetic character
How does genetic variation and mutations relate to each other?
mutation brings about variation which is the basis of evolution and the two types of variation are heritable and non-heritable
