100
Both traits are expressed in the phenotype
What is codominance
100
Symbol used to represent a male in a Pedigree chart
What is a square
200
Offspring of crosses between parents with different traits.
What is Hybrids
200
Genetic make-up of an individual
What is Genotype
200
A form of a trait that is always expressed
What is Dominant
200
The phenotype is somewhat in between the parents phenotype.
What is incomplete dominance
200
The % of offspring that will be male
What is 50%
300
Separation of alleles during gamete formation
What is Segregation
300
Physical characteristics of an organism
What is Phenotype
300
% of a recessive form in the offspring if both parents are heterozygous
What is 25%
300
The genotype and phenotype of offspring between yellow (Y) and blue (B) jelly fish, with incomplete dominance.
What is YB, green
300
The likelihood that particular event will occur
What is Probability
400

Interaction between genes where one has the potential to suppress the other.

Epistasis or Epistatic genes

400
Both Traits are expressed in the phenotype
What is codominance
400
What % of offspring will be recessive if one parent is heterozygous for a trait and the other homozygous recessive?
What is 0%
400
The genotype of parents who produce only AB type blood in their offspring.
What is homozygous AA and homozygous BB
400
When segregation of gametes occurs
What is Meiosis
500

YyWw x Yy Ww parents: 

If the probability of green seeds (yy) is 1/4 and the probability of Wrinkled seeds(ww) is 1/4, what is the probability that the offspring will have both Green and Wrinkled seeds (yyww). 

AND means multiply: 

1/4 * 1/4 = 1/16th or .0625  or 6.25%
