In a karyotype, ____________ are photographed, and then the images- paired. From this information, and we can study them to learn about_________________.
Spectral Karyotype (SKY)
a
traits, eye and hair color of an organisms

Mendel called plants that received different alleles for a trait from each parent _________________ .
a
genotype
b
recessive
c
purebred
d
hybrids
Question 3
What is true about a carrier of a recessive disorder?
a
The carrier has one copy of the allele and does not exhibit symptoms.
b
The carrier has one copy of the allele and exhibits symptoms.
c
The carrier has two copies of the allele and exhibits symptoms.
d
The carrier has two copies of the allele and does not exhibit symptoms
Question 4
The diagram shows a cross between two pink flowers.
What is the role of meiosis in creating variations in the offspring of this cross?
a
Meiosis allows alleles to separate, decreasing the variety of colors of the offspring.
b
Meiosis allows alleles to separate, increasing the variety of colors of the offspring.
c
Meiosis allows alleles to stay together, increasing the variety of colors of the offspring.
d
Meiosis allows alleles to stay together, decreasing the variety of colors of the offspring.
Question 5
Can YOU curl your tongue up on the sides?
Scientists Debunk Familiar Tongue-Rolling Lore | HuffPost Impact
We are pretending that tongue-curling in humans is a dominant genetic trait.
Suppose a man who is Tt for tongue-curling marries a woman who is also Tt for this trait. What are the possible genotypes and phenotypes of their children, and the percent chance for each?
Genotype Phenotype (curl or no curl) Percent Chance (number only)

Question 7
Premium Photo | Three little orange striped kitten on white background high resolution photoA common trait found in orange tabby cats is the following: being awesome (A) is dominant to being average (a).
A male cat that is homozygous dominant for the A trait is mated with a female cat that is homozygous recessive.
What is the probability that they will have an offspring who is heterozygous? out of

Question 8
On an extraterrestrial planet, which had organisms that reproduced with DNA the same way that organisms on Earth do, green little organisms have eyes that are triangular or round. Triangular eyes (T) are dominant to round eyes (t). A Punnett square was made to predict the offspring of two of these extraterrestrials with the genotypes Tt and tt. Use the Punnett square below to answer any questions that follow.
According to the Punnett square, what is the probability that an offspring would have triangular eyes?

Question 9
Chicken Dance GIFs | TenorIt is found that in cha-cha chickens, the allele for a double comb (A) is dominant to the allele for a single comb (a). A mother with the genotype Aa and a father with the genotype Aa produce an offspring.
What is the percent chance that the offspring will have a single comb?
