This term means different forms of a gene.

What are ALLELES? 

100
This describes how likely it is that an event will occur. 

What is PROBABILITY?

100

Genes are segments of code found on these structures. 

What are CHROMOSOMES? 

100

This term means an organism's genetic makeup or combination of alleles. 

What is GENOTYPE? 

100

This process produces two genetically identical body cells. 

What is MITOSIS? 

200
This type of allele always shows up when it is present.

What is a DOMINANT ALLELE?

200

In genetics, each event has no effect on this. 

What is the NEXT EVENT?

200
Chromosomes are found in this part of the cell.

What is the NUCLEUS? 

200
This term refers to the physical appearance or visible trait. 

What is PHENOTYPE? 

200

In a pedigree chart, which shapes are connected by a horizontal line?

What are a SQUARE and a CIRCLE; the PARENTS.
300
This type of allele is hidden whenever a dominant allele is present. 

What is a RECESSIVE ALLELE?

300
Every time two parents produce offspring, the probability of traits getting passed on is this.

What is the SAME?

300
This is the number of chromosomes found in human body cells. 

What is 46?

300
Having two identical alleles is described by this term.
What is HOMOZYGOUS?
300

This process reduces the number of chromosomes in half. 

What is MEIOSIS? 

400
If one parent donates a dominant allele and the other donates a recessive allele this trait will be expressed.

What is the DOMINANT TRAIT? 

400
What tool do scientists use to determine the probability of inheriting alleles? 

What is a PUNNETT SQUARE? 

400

During fertilization, this many chromosomes come from each parent. 

What is 23?

400

Having one dominant allele and one recessive allele is described as this.

What is HETEROZYGOUS? 

400

If parents are in Generation I on a pedigree chart, their children would be labeled as this generation.

What is GENERATION II?

500

What term describes an organism that has two identical alleles for a trait?

What is HOMOZYGOUS?

500
Scientists use Punnett Squares to determine the probability of inheriting these? 

What are ALLELES? 

500

Chromosome pairs that carry the same gene are called these. 

What are HOMOLOGOUS CHROMOSOMES? 

500

An organism with a dominant phenotype that still carries a recessive allele would present with this genotype? 

What is Dd?

500

An individual has the genotype Dd. Which type of allele is masked?

What is the RECESSIVE ALLELE (d)?
