In the case of regular dominance, dominant traits will hide a recessive trait.

An organism that has two identical alleles for a trait like TT or tt, is known as
Question 10
10.
A hybrid is the offspring of parents that have different alleles for a trait.
Question 11
11.
Recessive alleles are represented by a capital letter.
Question 12

If a person has a total of 46 chromosomes in their body cells, how many chromosomes are in their sex cells?
Question 13

Peas come in different colors!
Green is dominant and yellow is recessive.

Question 15
15.
Make a Punnett Square for a cross between two HETEROZYGOUS GREEN pea plants. (you may use whatever letter you would like)
2
Question 16
16.
What is the probability of the offspring from the cross you just did, having a phenotype of yellow?
Remember: Green is COMPLETELY dominant (no in-between phenotype) and yellow is recessive.
Question 17
17.
Draw a Punnett square below
Show all the probabilities (percentages) of the genotypes of the offspring
The parents are: a Medium Muscled (Mm) male and a Typical (mm) female cow. REMEMBER: MUSCLED COWS CAN HAVE HYBRIDS.
Question 18
18.
Draw a Punnett square below
Show all the probabilities (percentages) of the genotypes of the offspring
A male with type O (ii) blood has a child with a woman who is heterozygous for type A (Ai) blood.
Question 19
19.
Draw a Punnett square below
Show all the probabilities (percentages) of the genotypes of the offspring
In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele of white is W. The heterozygous phenotype is known as erminette (BW), meaning black and white feathers appear together.
Two erminette chickens were crossed. Show the Punnett Square
Question 20
20.
Where do we get our genetic information from?
Question 21
21.
Why are sex linked traits more common in males than in females?
Question 22
22.
What is the probability that the offspring of a homozygous dominant individual and a homozygous recessive individual will exhibit the dominant phenotype? You can use the Punnett Square attached to help you.
THIS IS FOR A COMPLETE DOMINANCE INHERITANCE (THERE IS NO HYBRID- no in-between phenotype)
