Genetics and Traits
The characteristics of an organism.
What are traits?
This gene always shows is self over a recessive gene
What is a dominant gene?
The passing of traits from parent to offspring is called.
What is heredity?
A plants response to light
What is phototropism?
What is asexual reproduction?
It is a type of reproduction that only requires one organism to reproduce.
Chromosomes are made up of _______.
What is DNA?
This describes two of the same copies of a gene
What is homozygous?
A variation of genes which leads to a diverse trait such as eye color, height, hair color, etc.
What is allele?
A plants response to touch.
What is thigmotropism?
What is sexual reproduction?
It is an organism that requires two organism to reproduce.
Where are chromosomes located?
What is the nucleus?
This describes different alleles for the same trait.
what is heterozygous?
It is made of DNA located in the nucleus; contains genetic information needed to carry out cell functions and make new cells.
What is chromosomes?
Geotropism means this.
A plants response to gravity
This type of reproduction passes down a mix of genetics to its offspring.
What is sexual reproduction?
True or False: Identical twins share 100% of their DNA. If it is false, fix the statement.
True
a capital letter represents what type of trait?
What is a dominant trait?
Behavioral characteristics or physical attributes of an organism that are expressed by genes and/or influenced by the environment.
What are traits?
Hydrotropism is a plants response to _________.
water
This offspring receives all of the genetic make up from its one parent. What type of reproduction?
What is asexual reproduction?
If we share DNA with our biological siblings, why do we look different?
We receive 50% of DNA from each parent, however, we do not know what 50% we will receive causing the genes to be different.
genes of a trait that is hidden when the dominant gene is present
What is a recessive gene?
A self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
What is DNA?
Why do roots grow down?
They grow down due to their response to gravity (geotropism)
What is an advantage of sexual reproduction?
You will have a mix of traits passed down to the offspring which will allow time for adaptations in order for organisms to adapt to their environments.
Where do we get our genetics from?
They are passed down from our biological parents.
A homozygous dominant spotted cow has Ss as its genotype. What is the genotype of an unspotted cow?
What is ss?
A unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
What is gene?
True or false: Plants wilt due to a lack of sunlight. If it is false, fix the statement.
False: They wilt due to a lack of water.
What is an advantage of asexual reproduction?
It will allow for the organisms to reproduce more offspring and quickly.
What is the difference between an inherited trait versus an acquired trait?
Inherited trait is something you are born with. An acquired trait is something you learn over time.
A dominant white bunny has a baby with a recessive brown bunny. It has two brown bunny offsprings. What is the genotype of its parents? Use W and w.
What is Ww and ww?
________ would be defined as the best science teacher.
Ms. Boyett
A plant that is growing up a fence is an example of what type of tropisms?
Thigmotropism
How do we know if an offspring was produced asexually or sexually?
We would look at their DNA to determine if it is 100% from the parent or 50% from the parent.
