What letter do we use to designate a dominant trait?
A capital letter
The study of heredity and DNA is called....
genetics
True or False: An Acquired Trait and a Learned Behavior are the same thing
TRUE!
What does DNA stand for?
Deoxyribonucleic acid
Give me an example of an eye phenotype
Green eyes, blue eyes, brown eyes, etc.
What is a dominant trait?
A trait that is more likely to be displayed in an offspring.
Explain what a heterogeneous organism is.
The diagram often used by biologists to determine the probability of an offspring having a particular genotype is called....
Punnett Square
A person with XX Chromosomes would be what gender?
Female
A person with XY chromosomes would be what gender?
Male
What is the difference between a phenotype and a genotype?
A phenotype is what an organism actually looks like. A genotype is the combination of alleles or genetic code of an organism.
What is the definition of an allele?
It is a specific form of a trait.
What is a carrier?
A carrier is an organism that is carrying a trait but does not display it in it's phenotype
What is the scientific name for parents' children?
Offspring
What is a possible explanation for why two blue eyed parents have a brown eyed offspring?
1. A mutation occurred, causing a brown eye allele to develop.
OR
2. One or both of the parents are CARRIERS of the brown eye gene
Explain how two people can have the same phenotype but different genotypes
However, both people would display the dominant allele in their phenotype.
What is the name of the new gene-editing program that allows humans to "program" and "edit" genes to create desired phenotypic outcomes?
CRISPR
How many PAIRS of chromosomes do humans have?
23 pairs
What is the shape of DNA?
a double helix
What is the definition of an acquired trait?
A trait or characteristic that an organism is NOT born with.
g = recessive yellow eyes
If a Gg male is crossed with a Gg female, what is the probability that their offspring will have yellow eyes?
25%
13 years (1990-2003)
T = dominant Tall
t = recessive short
A homogeneous short plant named Eva has two heterogeneous tall parents. What was the probability that Eva would be a short plant?
25%
Both parents are Tt so the Punnett Square would have TT, Tt, Tt, and tt as options. 1/4 = 25%
F = dominant fire breathing
f = recessive non fire breathing
A Heterogeneous fire breathing dragon's mother is non fire breathing. What are the possible GENOTYPES for the dragon's father?
Ff
OR
FF
Who is considered the "father of genetics"? (The pea guy)
Gregor Mendel
