The word "heredity" is best defined as....
The passage of knowledge from parents to offspring.
The passage of visible features from one generation to the next.
The passage of genetic information from parents to offspring.
The passage of dominant genes from one generation to the next.
Some countries contain more blonde haired people, a recessive trait, than other countries. How can heredity cause this trend?
Hair color is part of a country's culture, so many of the people born in a country all have the same hair color.
The weather of an area determines the appearance of people living in that area.
Blonde people carry a gene that causes their offspring to have blonde hair no matter the hair color of the other parent.
Blonde people in these countries are reproducing with other blonde people, passing down genes that have instructions for blonde hair color.
What is one advantage to reproducing sexually?
The offspring have greater genetic variety and are more able to survive environmental changes.
The offspring will have all of the same traits as the female parent making them more likely to survive.
A single individual can produce many offspring in a shorter period of time increasing the likelihood of the population’s survival.
The offspring are less likely to have variations in their traits that could be harmful to their survival.
Offspring could only be produced through asexual reproduction.
Offspring is not identical.
Offspring is identical.
Offspring could only be produced through sexual reproduction.
Offspring is not identical.
Offspring is identical.
Students observe their physical traits and record their ear shape. What is responsible for the different shapes of students' ears?
then environmental factors
the genetic material inside the cytoplasm of their blood cells
the genetic material inside the mitochondria
the genetic material inside their cells' nucleus, where their chromosomes are located
If two tall plants are cross-pollinated and the result is a short offspring plant, what genotype must each tall parent have?
TT
Tt

How do plants that grow from the fertilized seeds, sexual reproduction, compare to plants grown from the bulbs, asexual reproduction?
They will be different, because only the plants grown from the bulbs will be genetically identical to the original plant.
They will be different, because only the plants grown from the seeds will be genetically identical to the original plant.
They will be same, because plants grown from both seeds and bulbs will be genetically identical to the original plant.
They will be same, because plants grown from both seeds and bulbs will be genetically identical to each other but not to the original plant.
