Vocabulary
100
Genetically, what is an advantage of sexual reproduction?
An advantage of this type of reproduction is that organisms are genetically diverse.
100
What are inherited traits.
Traits that you get from your parents.
100
What base always goes with thymine (T)
adenine (A).
100
Where do parents go?
Outside the box. One on top - one on left side.
100
What is a dominant allele
This allele will show up if it is present.
200
What is asexual reproduction
In this type of reproduction, cells undergo mitosis to make exact copies or clones of the parent cell.
200
What is an acquired trait or environmental factor.
Your accent comes from your environment, so it is this type of trait.
200
What must be done before Mitosis?
A copy of the DNA must be made.
200
Draw a punnett square for two critters with orange tails.
All tt - including parents
200
What is an allele
Different forms or "varieties" of a gene.
300
This blood type is considered to be "recessive."
What is Type O
300
False
True or false. All traits are determined by one gene.
300
A change in the DNA of a gene that can lead to a different trait.
what is a mutation?
300
Draw a punnett square with two heterozygous parents for tail color.
TT, Tt, Tt, tt
300
An organism that has two identical recessive alleles for a specific trait
Explain what Homozygous recessive means.
400
What is positive.
A person that gets a positive Rh factor from mom and a negative Rh factor from dad will have this Rh factor.
400
What is incomplete dominance. Give a simple example.
An example of this would be combining a red flower with a white flower to get a pink flower.
400
What DNA does stand for?
Deoxyribonucleic acid
400
What is the chance of a having a orange tail with two Homozygous dominant parents?
0%
400
What is the relationship between genes, chromosomes and DNA?
Genes - A specific sequence of DNA that determines one or more traits. DNA - a long double-helical molecule, that contains the genes. Chromosomes - A strand of DNA—and sometimes associated proteins—that contains the genes that store hereditary information.
500
Dad has type A blood and Mom has type B blood. In order to have a child with type O blood, these must be their genotypes.
What is type AO and type BO
500
What is co-dominance
If you have type AB blood, then you are showing this type of inheritance for blood type.
500
What are the results of mitosis versus meiosis in terms of Chromosome numbers?
Mitosis 46 to 46 Meiosis 46 to 23
500
Show a punnett square that shows blood types of the offspring. One parent is AO and one parent is BO.
AB, A, B, O
500
What is the difference between genotype and phenotype?
Genotype - An individual’s pair of alleles for a specific gene or group of genes that determine a trait. Phenotype - An organism’s observable traits.
