These types of genotypes have different genes.
Hint: It begins with "H."
Heterozygous.

This is the definition of phenotype.
Phenotype is what you see because of the genes.

Parent One - HH
Parent Two - hh
Draw the Punnet square to represent this breeding.
'Square'
200
These types of genotypes have the same genes.
Hint: Also begins with "H."
Homozygous.

If brown hair is dominant to blonde hair, what phenotype would you see with a genotype of BB?
Brown hair.

If both parents are homozygous recessive, how many of their kids (out of 4) will have the dominant phenotype?
0

Give me an example of a heterozygous genotype.
Hh, Ff, etc.

If big lips is dominant to small lips, what phenotype would you see with a genotype of ll?
Small lips.

Draw a Punnet square where both parents are heterozygous for blue feathers. Use F for the dominant gene.
Drawn square.

Give me TWO examples of homozygous genotypes, one for dominant, and one for recessive.
HH, hh, FF, ff, etc.

'A' is dominant for long arms, 'a' is recessive for short arms. If John is heterozygous, what phenotype does he have?
Long arms.

Draw a Punnet square where one parent is homozygous dominant and one parent is homozygous recessive. Use G as the dominant gene.
Drawn square.
500
What is the definition of genotype?
Hint: 2 genes make a genotype.
A combination of genes.

'H' is dominant for straight hair and 'h' is recessive for curly hair. What is the phenotype for the homozygous recessive genotype?
Curly hair.

If one parent is homozygous dominant and the other parent is heterozygous, what percentage will the children have the recessive phenotype? Draw a square to figure this out.
