In the Punnett Square shown below, what is TRUE about the offspring?
In the Punnett Square shown below, what is TRUE about the offspring?
Mendel discovered that, in pea plants, round seed shape was dominant, and wrinkled seed shape was recessive. What does this mean?
Mendel started with what he called “pure-bred” and "True-bred" yellow & green seeds. What term would modern scientists use instead of “pure-bred”?
In the Punnett Square shown below, what is TRUE about the offspring?
The outward appearance of an organism is referred to as its:
An individual that has sickle cell anaemia has the genotype Ss. This genotype is said to be:
A human zygote will develop into a male if it contains:
Dominant characteristics are so named because they:
On the diagram below, if you crossed a YY = yellow and yy = green, then the genotype of ALL of the F1 offspring would be:
A person that has the allele for a particular phenotype but it is not expressed is referred to as a:
Blood types include the phenotypes A, B, O and AB blood types. AB blood type is an example of
Red coats in wolves (R) are dominant to white coat colour (r)
The phenotype for a wolf with the genotype Rr would be:
Red coats in wolves (R) are dominant to white coat colour (r)
The genotype for a red wolf would be:
Two genes for coat colour in dogs have the following alleles.
Gene 1 Gene 2
B : black S : solid colour
b : brown s : white spotting
It is reasonable to conclude that a dog with the genotype
Which of the following genotypes belongs in the red box in the Punnett square?
In horses, the allele for a bay coat (brown with black mane, tail and legs) and the allele for a cream coat can combine to make a buckskin coat.
The allele B is used for bay; C is used for cream.
Buckskin horses have one bay allele and one cream allele (BC).
The genotype BC makes a buckskin coat, as neither allele is dominant.
Cross a bay stallion with a cream mare. What are the offspring phenotype percentages? Show your work for full credit.
In Mendel's experiments with pea plants, he crossed a homozygous round yellow seed plant (genotype RRYY) with a homozygous wrinkled green seed plant (genotype rryy). What genetic principle explains the variation in the offspring's traits?
A male and female child have three copies of chromosome 21. Although both parents are unaffected, their doctor explains that the disorder associated with having an extra chromosome 21, known as Down syndrome, results from a chromosomal mutation during the formation of reproductive cells. Which argument best supports this claim?
The diploid chromosome number for domestic cats (Felis catus) is 38. A somatic cell would have chromosomes while a gamete would have .
Which genotype could taste the PTC paper?
_____ is a form of a gene
A dominant allele is represented by a
A recessive allele only shows up if there is NOT a dominant allele
It requires ____ dominant allele(s) for the trait to "show up"
Homozygous means two uppercase OR two lower case (ex: HH or hh)
_______ shows the allele combination such as HH or Hh.
_______ shows how the allele presents itself (hair or hairless)
Purebred for "hair" would be
If the cat was hairless but a hybrid genotype for liking sinks, what would be the genotype?
What is the genotype for a cat that has hair but hates sinks?
How many chromosomes does a gamete have compared to a body cell?
What method do they really like?
Mendelian genetics states that as long as there is ____ dominant allele, then it will show in the phenotype.
The pink flower has the genotype of:
The pink flower is
Incomplete dominance showed us that if one dominant allele is present (R for red), then it will show only that allele.
The alleles are "mixed" together
Both alleles show up.
Height and skin color is determine by a single gene each.
Which allele controls the expression of others?
What is the probability of the llama being albino?
