Tall stems (T) are dominant to short stems. The offspring are all short stemmed. What are the genotypes of the parents?
If T = tall stem and t = short stem, then both parents are tt.
Long eyelashes (L) are dominant to having short eyelashes and tongue rolling (T) is dominant to not being able to roll tongue. The wife is homozygous dominant for long lashes and heterozygous for tongue rollling. The husband has short lashes and is homozygous dominant for tongue rolling. Write the parents genotypes.
If L = long lashes and l = short lashes and T = tongue rolling and t = no tongue rolling
then parent 1 is LLTt and parent 2 is llTT.
Enzymes are made of which macromolecule:
A) Carbohydrates
B) Proteins
C) Lipids
D) Nucleic Acids
B) Proteins

Long hair (L) is dominant to short hair in cats. Two cats mate and always produce long haired kittens. One parent has short hair. What is the genotype of the other parent?
L = long hair and l = short hair. If one parent has short hair (ll), then the other parent must be LL to always have kids that have long hair.
Tall stems (T) are dominant to short stems and round seeds (R) are dominant to wrinkled seeds.
A parent is heterozygous for tall stems and has wrinkled seeds.
What are the 4 sets of alleles that should be written on the outside of the dihybrid punnett square?
Use 2 small punnett squares.
If T = tall stems and t = short stems and R = round seeds and r = wrinkled seeds
then the parent's genotype is Ttrr. The four sets of alleles are: Tr, tr, Tr, and tr.
The pH of Windex is 10. What type of solution is this? A) Acidic
B) Basic
C) Neutral
B) Basic
Set the timer for 3 minutes.
Round seeds are dominant to wrinkled seeds. If two heterozygous round seeded plants cross, what is the probability in fractions that they would have wrinkled seeded offspring?
25%
Purple flowers (P) are dominant to white flowers and tall stems (T) are dominant to short stems. What is the phenotype for Pptt?
purple flowers and short stem
Get the punnett square from the teacher add tell her "Dihybrid Punnett squares for 300".
In rabbits, grey fur (G) is dominant to white fur (g) and black eyes (B) are dominant to red eyes (b).
Refer to the punnett square picture. What are the 2 missing genotypes in punnett square?
bbDd and BbDd
Who is the founder of genetics?
Mendel

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 have no dimples?
0%
Get the punnett square from the teacher add tell her "Monohybrid or Dihybrid Punnett squares for 400".
Set the timer for 3 minutes.
Having brown eyes (B) is dominant to having green eyes (b) and having freckles (F) is dominant to not having freckles (f).
Refer to the picture to answer the question - In fractions, how many offspring will have brown eyes but no freckles?
4/16
In tomatoes red fruit (R) is dominant to yellow fruit (r) and tall vines (T) are dominant to short vines (t).
One parent is heterozygous for red fruit and heterozygous tall vines.
The other parent is homozygous for red fruit and has short vines
What are the parents' genotypes?
Parent 2: RRtt
If I play music to plants everyday, then they will grow taller. What is the dependent variable of this hypothesis?
Height
Set the timer for 3 minutes.
Yellow seeds (Y) are dominant to green seeds. Two yellow seeded plants cross to have green seeded offspring. What are the parents' genotypes?
If Y = yellow seeds and y = green seeds, then both parents will be heterozygous (Yy and Yy)
Get the punnett square from the teacher add tell her "Monohybrid or Dihybrid Punnett squares for 500".
Set the timer for 3 minutes.
Having brown eyes (B) is dominant to having green eyes (b) and having dimples (D) is dominant to not having dimples (d).
Refer to the punnett square picture. In fractions, how many offspring will have green eyes and no dimples?
1/16.
Set the timer for 3 minutes.
In tomatoes, red fruit (R) is dominant to yellow fruit and tall vines (T) are dominant short vines.
A parent is heterozygous for red fruit and heterozygous for tall vines.
What are the alleles that would be written outside the dihybrid punnett square
RT, Rt, rT, and rt
Name a difference between mitosis and meiosis
Possible answers: mitosis produces 2 identical diploid cells and meiosis produces 4 different haploid cells. Mitosis divides somatic cells and meiosis divides gametes. Meiosis undergoes 2 divisions and mitosis goes through one division. Crossing over only occurs in meiosis, not mitosis.
If your answer is not shown above but you can prove it by finding it in your notes, then you can get the points.
