An organism with 2 different alleles for a trait is called a ______.
heterozygous
300
The tool used to show all of the possible outcomes of a genetic cross.

300
This type of organism has 2 different alleles for a trait
Heterozygous
300
What percent of offspring will be homozygous dominant?

Hair color is an example of which type of inheritance, when groups of alleles control the trait?
polygenic inheritance
400
This occurs when 2 traits are neither dominant nor recessive, both show up.
co-dominant / codominance
400
Cross a homozygous dominant parent with a heterozygous parent. What are the genotypes
75% homozygous dominant, 25% heterozygous

This is the passing of physical characteristics from parent to offspring.
Heredity
500
This was the scientist who first began studying heredity and genetics.
Gregor Mendel
500
Different forms of a gene.
alleles
500
Neither trait is dominant over the other and the two blend together.
Incomplete Dominance
500
A segment of DNA, controls inherited traits
