What is Codominance
What is an offspring
A long tailed dog (L) and a short tailed (S) dog mate to produce all medium length tailed puppies. What is the genotype of the medium length tailed puppy?
LS or SL
If I am homozygous for the B allele, and my husband is type "O". What are all the possible blood types of our babies
What is b only
Many traits, such as stem length in plants and skin color and height in humans, are controlled by two or more genes. What is this called
What is polygenic inheritance
Curly hair is recessive, and straight hair is dominant. a woman with curly hair marries a man who is heterozygous for straight hair. Use a Punnett square to determine what percentage of their offspring will have curly hair
What is 50%
Long tailed dogs (L) and short tailed (S) dogs create medium length tailed puppies. What if two parents are heterozygous? What are the chances in percent that they will have a short tailed puppy? You can set the timer to 2 minutes!
25%
If you have the following:
Dominate black fur = B,Recessive white fur = b,
Dominate rough fur = R,Recessive for smooth fur = r
Cross a heterozygous parent (BbRr) with a heterozygous parent (BbRr)
What is the probability of producing black, rough fur?
What is 9/16
The term for having two identical alleles for a gene
homozygous
Round seeds are dominant to wrinkled seeds. If two heterozygous round seeded plants cross, what is the probability in percent that they would have wrinkled seeded offspring? You can set the timer to 2 minutes!
What is 25%
Pea plants with dominant Round (R) and Yellow (Y) seeds. What will be the phenotypic ratio of: Round/Yellow: Round/Green: wrinkled/Yellow: Wrinkled/green if both parents are hybrids.
What is 9:3:3:1
In rabbits, grey fur (G) is dominant to white fur (g) and black eyes (B) are dominant to red eyes (b). One parent is GgBb and the other parent is ggBb. What is the probability in fractions that they will produce offspring that have grey fur and black eyes? You can set the timer to 5 minutes!

Long tailed dogs (L) and short tailed (S) dogs create medium length tailed puppies. What are the parents' genotypes if the offspring has a 50% chance of being short tailed or 50% chance of being medium tailed? You can set the timer to 2 minutes!
One parent is SS and the other parent is LS.
Having dimples is dominant to not having dimples. Create a punnet square of a parent that is homozygous dominant for dimples and a parent that is heterozygous for dimples. What is the probability in percent that they will have offspring that don't have dimples? You can set the timer to 2 minutes!
What is 0%
Snapdragons are flowering plants that are incomplete dominance of red flowers over yellow flowers. If a red flowering plant is crossed with a yellow flowering plant what is the result?
what is all of the offspring will have orang flowers
A long tailed dog and a short tailed dog create medium length tailed puppies. Give one reason why this is an example of incomplete dominance.
Either answer is acceptable - 1) There is a 3rd phenotype. 2) The 3rd phenotype is a blend/mix of the parents' phenotypes
In tomatoes red fruit (R) is dominant to yellow fruit (r) and tall vines (T) are dominant to short vines (t). Both parents are heterozygous for red fruit and tall vines. What is the probability in fractions that the offspring will be RrTT? You can set the timer to 5 minutes!
