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.

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

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

In the case of regular dominance, dominant traits will hide a recessive trait.
True
False
A carrier is a person who has
dominant alleles for a trait          Â
recessive alleles for a trait
one recessive and one dominant allele
When an alelle masks (or hides) another allele it is known as a
Gene

A heterozygous organism has
two identical alleles for a trait.

Question 15

Make a Punnett Square for a cross between two HETEROZYGOUS GREEN pea plants. (you may use whatever letter you would like)
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.
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)
