The picture shows a sperm fertilizing an egg. We know this is sexual reproduction because
The offspring will have the exact same genes as the parent.
The offspring receives its genes from one parent
The offspring has the exact same traits as its parents
The offspring receives its genes from two parents
This picture shows several forms of Asexual reproduction. What is true about asexual reproduction?
It involves only one parent.
Offspring have unique DNA different for either parent
It involves two parents
It helps creates variety in a population
Which statement is true about stem cuttings
Offspring can produce different colored flowers from the parent.
Cutting is a form of sexual reproduction
Offspring will have the same DNA as their parent and the same colored flowers
Cutting is not a form of reproduction
Which is true about cross pollination?
It is sexual reproduction because it involves 2 parents
it is asexual reproduction because it involves 2 parents
it is sexual reproduction because it involves 1 parent
it is asexual reproduction because it involves 1 parent
It this example, yellow is dominant over green. What percent of offspring will have yellow pods?
0%
50%
75%
100%
Why don't we use punnett squares to predict the offspring in asexual reproduction?
Results are too unpredictable in asexual reproduction
It is not possible to know the DNA of the parents
Offspring have the exact same DNA as their parent in asexual reproduction
Asexual reproduction uses more than two parents
If A is the allele for the dominant trait of dimples, what is the percent chance that the offspring will have dimples?
0%
50%
75%
100%
What percent of the offspring would be heterozygous
0%
50%
75%
100%
Chromosomes are made of:
DNA
Ribosomes
Mitochondria
Cells
Genes for a particular trait are stored where on chromosomes
Anywhere on the same corresponding chromosomes
Anywhere on any two chromosomes
In the same location on two corresponding chromosomes
In the same location on any two chromosomes
Where are genes located
In the ribosomes of the cell
In the Mitochondria of the cell
In the chromosomes inside the nucleus of the cell
At Old Navy in the Mall
Genes are the code (recipe) for the production of what?
Carbohydrates
Amino Acids
Nucleotides
Proteins
What is the most common result of a permanent mutation for an organism
The mutation creates positive new trait for the organism
The mutation creates a negative new trait for the organism
Mutations cannot create new traits.
Mutations do not occur in living organisms
If a genetic mutation results in a different trait, what is true about the individual who has the mutation
He is making a different protein than others.
He does not make any proteins
He is making different amino acids than others
He is making different nucleotides than others
Which statement is false
Mutations can be beneficial to an organism
Mutations can be harmful to an organism
Mutations may have no affect on an organism
Mutations cannot be passed on from parents to offspring
Which process did humans use for over thousands of years to create the many different breeds of dogs
Selective breeding
Gene therapy
Genetic engineering
Natural Selection
An agricultural geneticist wanted to create a small watermelon that grows on trees. Which process might he use to create this entirely new trait in watermelons?
Selective breeding
Gene therapy
Genetic engineering
Natural selection
A medical geneticist wanted to cure a genetic disease by fixing a mutation that causes the disease. Which process would this be?
Selective Breeding
Gene Therapy
Genetic Engineering
Natural Selection
Which is not true about Gene Therapy?
Patients may experience an immune reaction to gene therapy
Gene therapy may result in infections or tumors
It is possible the therapy may end up targeting the wrong cells
Gene therapy is a simple procedure
Which is not true about gene therapy and genetic engineering
They both can be used to target an individual trait
They are both relatively new and experimental.
They are both relatively expensive and somewhat controversial
They have both been around longer than selective breeding
