Reproduction
Mendel
Dominance
100
A trait that you get from your parents (genes)
Inherited Trait
100
What are the chances (%) of the offspring showing the dominant characteristic?
Every box has at least 1 capital so 100%
100
A diagram used to show how parent’s alleles might combine in offspring
Punnett Square
100
Type of reproduction that involves 2 parents and results in offspring that are different than the parents.
Sexual Reproduction
100
What is the name (FIRST AND LAST NAME) of the Austrian monk that conducted pea plant experiments and became known as the "Father of Genetics"?
Sir Gregor Mendel
100
Complete dominance occurs when a dominant gene completely overrides a recessive gene. What is a genotype for Complete Dominance? Write the allele combination on your board.
Bb, As, Tt, Rr, etc
200
A trait that is developed over your lifetime
Acquired Trait
200
What would the father's genotype or allele combination be?
Heterozygous (Rr)
200
One type of allele for a trait is present (AA or aa)
Homozygous
200
Type of reproduction that involves 1 parent and ends with identical offspring?
Asexual Reproduction
200
What did Sir Gregor Mendel study in his first genetic experiments?
Pea Plants
200
What is the only genotype possible in order to not show the dominant phenotype?
bb, aa, tt, rr, etc
300
Traits are passed down from parent to _____________ during reproduction.
offspring
300
What genotype or allele combination would be present in the bottom, right corner of this Punnett square?
Homozygous Recessive (aa)
300
Two different alleles for a trait are present (Aa)
Heterozygous
300
What is the only 2 forms of sexual reproduction? Hint: the union of a sperm and egg cell / the union of a pollen and ovum?
Fertilization and Pollination
300
According to Mendel, what is the possibility (%) that the offspring will show the recessive trait?
2 boxes have no capital letters so 50%
300
Is the following definition for complete dominance, incomplete dominance or co-dominance?
The dominant allele completely overrides the recessive allele resulting in the dominant phenotype showing.
Complete Dominance
400
What are 2 inherited traits?
Eye Color
Hair Color
Tongue Rolling Ability
Bone Structure
Hair Texture
400
What would be the only possible solution genotype or allele combination for the cross of a homozygous dominant organism vs a homozygous recessive organism?
Heterozygous (Hh)
400
The genes or allele combination for a characteristic
Genotype
400
What are 3 forms of asexual reproduction?
Binary fission (mitosis)
Budding
Fragmentation
Vegetative Propagation
Parthenogenesis
400
According to Mendel, what is the possibility that the offspring would be Heterozygous?
2 boxes have 1 capital letter and 1 lower case letter so 50%
400
Is the following definition for complete dominance, incomplete dominance or co-dominance?
The dominant and recessive phenotype are not expressed but instead are blended together.
Incomplete Dominance
500
What are 2 acquired traits?
Walking
Talking
Tattoos
Piercings
Hair Length
500
Complete the Punnett square below and list the possible genotypes or allele combinations and their associated percentage %.
TT = 25%
Tt = 50%
tt = 25%
500
The actual characteristic that is observed
Phenotype
500
Why is it important to have sexual reproduction? Your answer must refer back to what I talked about in class.
Genetic Diversity!!!
Better Answer: So that individuals of a species can adapt to changing environments so the species does not go extinct. To help a species to survive.
500
According to Mendel, how would you describe the genotypes of the mother and father? (HINT: Think of the words he would use)
Father =
Mother =
Father = Homozygous Recessive (gg)
Mother = Heterozygous (Gg)
500
Is the following definition for complete dominance, incomplete dominance or co-dominance?
Both dominant alleles are represented in the same phenotype.
Co-Dominance
600
The passing of traits from parent to offspring.
Heredity
700
The scientific study of heredity.
