Genetics
What is genetics?
The study of heredity.
What is heredity?
The passage of genetic instructions (traits) from parent to offspring.
Sexual reproduction produces offspring that are genetically _____________ to the parents.
Similar
When a part grows back it is called
Regeneration
How are traits passed from parent to offspring?
Through genes during reproduction
Where are genes located?
In the chromosomes
The number of characteristics contained in an organism's genetic make-up?
diversity
Asexual reproduction produces offspring that are genetically ____________ to the parent.
Identical
Three types of asexual reproduction are:
budding, binary fission, and regeneration
Name two traits that could be inherited from a parent?
Examples: hair color, eye color, height, skin color, freckles, etc...
What are the threadlike structures of DNA that carry genes called?
Chromosomes
What determines acquired traits?
outside influences like family and school
What is an advantage of asexual reproduction?
They can reproduce quickly and in large numbers
Are blood cells or intelligence inherited from your parents?
blood cells
What do you call a row of ancestors from different time periods?
Generation
Inherited traits that children get from their parents come from-
Genes
Traits passed on through asexual reproduction are:
identical to the parent
What is a disadvantage of asexual reproduction?
They can be slowed or destroyed by environmental changes.
which creates more diversity: sexual or asexual reproduction?
sexual
What is the benefits of being able to reproduce both sexually and asexually?
Organism is not limited so therefore reproduction can continue even though environmental changes may occur. (ex. planarian, starfish)
What do we call different traits passed to offspring from their biological parents?
genetic variation
How many chromosomes do humans have?
46 or 23 pair
The sorting of chromosomes during sexual reproduction, determines -
Which traits are passed on to the offspring
Which form of reproduction has a uniform(identical) group of offspring: asexual or sexual?
Asexual
How can increased genetic variation improve offspring survival rate?
It increases the variety of genes creating stronger organisms more fit for survival.
