Peas pick me
When Mendel crossed purebred pea plants having green pods with purebred pea plants having yellow pods, the offspring were all
Hybrid peas with all green pods
Alleles for a dominant trait are represented with _______ letters.
Uppercase
What is the process by which organisms with certain adaptations survive to pass on their traits to a greater number of offspring?
Natural Selection
Both traits are present in hybrid offspring, but without blending
Codominance
What was Darth Vadar's real name?
Anakin Skywalker
The pod color of pea plants is controlled by only one gene that has only two possible alleles
Simple dominance
A Tt plant is crossed with a tt plant. What genotype(s) would you expect the offspring to have?
Some Tt and some tt
True or False: Natural selection has been observed to create new kinds of organisms
False
Different forms of genes that result in different traits are known as ______.
Alleles
Which of the following is an example of codominance?
Pink snapdragon flower color
Crossing a tall plant and a short plant to produce a medium plant
Crossing a pea plant with round seeds and a pea plant with wrinkled seeds to produce a pea plant with round seeds
Crossing a white horse and a black house to produce a horse with both black hairs and white hairs
Crossing a white horse and a black house to produce a horse with both black hairs and white hairs
Gregor Mendel used pea plants to study heredity for all of the following reasons except
That it was relatively easy to cross different pea plants in order to observe the resulting offspring
That their characters, like pod and color and height, were easy to observe
That the characters Mendel studied had at least two identifiable traits
That many characters such as pod color and seed shape were controlled by a dozen or more interacting genes
That many characters such as pod color and seed shape were controlled by a dozen or more interacting genes
If a father is purebred for the dominant trait of dimples (DD) and a mother is purebred for not having dimples (dd), then you should expect the couple’s children
To all be Dd
Where do creationists and evolutionists disagree on the effects of natural selection?
Creationists do not believe that natural selection is able to allow all creatures to descend from an original common ancestor.
Two traits produce a blended phenotype
Incomplete dominance
Which of the following is a phenotype?
Bb
Black fur
A pea plant
A Punnett square
Black fur
Which of the following is not one of Mendel’s three principles of heredity?
In a cross of purebred parents, all offspring will show the dominant trait
In a cross of hybrid parents, all offspring will also be hybrid
Two alleles for a parent’s gene separate and then each combines with an allele from the other parent to determine the offspring’s trait
Each allele is passed to the offspring independently of the other alleles
In a cross of hybrid parents, all offspring will also be hybrid
A population of foxes migrates into a desert region. The number of foxes with larger ears is most likely to....
Increase
Where do creationists and evolutionists agree on the effects of natural selection?
Natural selection affects populations and that those populations do change when the environment favors certain traits.
A gene has more than two possible alleles
Multiple alleles
Which movie series is Miss Robinson currently watching through?
1. Star Wars
2. Twilight
3. Harry Potter
4. Hunger Games
Staw Wars
A purebred pea plant with green pods (PP) is crossed with a hybrid pea plant with green pods (Pp). What is the probability that an offspring will be hybrid?
50%
The allele for tall pea plants is dominant over the allele for short pea plants. Suppose a hybrid plant is crossed with another hybrid pea plant. Create a Punnett square for the cross.
Insert regular hybrid Punnett square here
How does natural selection affect a population differently than genetic drift does?
Natural Selection causes the traits that best help an organism to survive and reproduce to be passed on more frequently. Genetic drift is random and unpredictable.
Two or more genes interact to produce a single trait
Polygenic inheritance
Genetic drift would most likely occur in which of the following populations?
A greenhouse of snapdragons
An orchid with thousands of orange trees
A pea plant farm
A petting zoo with a dozen pygmy goats
A petting zoo with a dozen pygmy goats
