100
A process of cell division that forms two new nuclei, each of which has the same number of chromosomes (cell division).
What is mitosis?
100
Number of parent cells needed for sexual and asexual reproduction to occur.
What is one parent cell for asexual reproduction and two parent cells for sexual reproduction?
100
The passing of genetic material from parent to offspring.
What is heredity?
100
Describe how you would represent male and females on a pedigree.
What is a circle (female) and a square (male)?
100
The use and application of living things and biological processes.
What is biotechnology?
200
Number of new daughter cells formed at the end of mitosis and meiosis?
What is mitosis-2 and meiosis-4?
200
Describe what the offspring of asexual reproduction look like compared to their parent cell.
What is genetically identical?
200
When one trait covers or masks another form of the trait.
What is dominant?
200
Describe how you tell if a male of female is a carrier of the trait you are tracing on a pedigree?
What is they are half colored in?
200
To make a genetic duplicate of an organism, cell, or piece of genetic material.
What is cloning?
300
List of the phases of mitosis/meiosis in order.
What is interphase, prophase, metaphase, anaphase, telophase, and cytokinesis?
300
Name the four bases of DNA and tell which ones pair together.
What is adenine pairs with thymine and guanine pairs with cytosine?
300
Describe what the backbone of DNA is composed of and include where the bases attach.
What is phosphate and sugar group and bases attach to the sugar group?
300
Create a Punnett Square with genotypes BB and bb. B=brown eyes and b=blue eyes. Name percentage of each genotype.
What is 100% brown eyes?
300
The human practice of breeding animals or plants that have certain desired traits.
What is artificial selection?
400
Difference between diploid and haploid.
What is diploid describes the chromosomes at the end of mitosis (two sets) and haploid describes the chromosomes at the end of meiosis (one set)?
400
Describe how bases are different in RNA.
What is RNA has uracil instead of thymine?
400
Describe the difference between inherited trait and learned behavior and give an example of each.
What is an inherited trait is a physical characteristic that is passed from parents to offspring (ex. eye color) and a learned behavior is any type of behavior you have to be taught (ex. cooking)?
400
Draw a Punnett Square with the genotypes Rr and rr. R=round seed and r=flat seed. Name the percentages of round and flat seeds.
What is 50% round and 50% flat?
400
A technology in which the genome of a living cell is modified for medical or industrial use.
What is genetic engineering?
500
Briefly explain what happens in each phase of Mitosis/Meiosis.
What is interphase-cell not dividing, longest phase, prophase-first phase of division (chromosomes become visible), metaphase-chromosomes line up in middle of cell, anaphase-chromosomes pull apart, telophase-cells start pinching inward, and cytokinesis-two new cells?
500
Name the three types of mutations and describe each one.
What is deletion-base left out or removed, insertion-extra base put in, and substitution-base is replaced?
500
Difference between codominance and incomplete dominance.
What is codominance-both are expressed (red and white spotted flowers and incomplete-both are mised (pink flowers)?
500
Draw a pedigree tracing blonde hair color. Blonde-haired Anita and dark-haired Harlan are married. They have three kids, dark-haired John, dark-haired Nancy, and blonde-haired Jennifer. Jennifer has three kids: blonde haired Gunnar, dark-haired Madelyn, and blonde haired Rowan.
Ms. Johnson will check the pedigree.
500
Explain an example of artificial selection.
Ms. Johnson will take all reasonable answers.
