Genetics Vocab
A characteristic of an organism, like flower color, fur, texture or height.
Trait
Different versions of the same gene.
The model used to predict possible outcomes in offspring
Punnett Square
This type of allele determines the phenotype when only one copy is present.
Dominant Allele
An increase in size or mass.
Growth
A living thing, such as a human, animal, or plant.
Organism
The combination of alleles an organism has.
Genotype
The percent change each of the four boxes in a Punnett Square represents.
25%
This type of allele only shows up when two copies are present
Recessive Allele
Changes in an organism's structures and functions as it matures.
Development.
The study of how characteristics are passed from parents to offspring.
Genetics
The observable characteristics of an organism, which can also be affected by the environment.
Phenotype.
Two Bb parents are crossed. This is the chance their offspring will be bb.
25%
True of False: a dominant allele is always the more common one.
Food, water, sunlight, and temperature are all examples of these factors.
Environmental
The passing of genetic information from one generation to the next.
Heredity
The term for a genotype with two identical alleles, like BB or bb.
Homozygous.
A BB parent is crossed with a bb parent. This is the genotype of every possible offspring.
Bb. (100%)
This ration describes how often different allele combinations are expected.
Genotype Ratio
The range of growth outcomes supported by an organisms inherited genetic information, which does not guarantee a specific outcome.
Genetic potential.
Structures that contain DNA and many genes.
Chromosomes
The classification of the genotype Aa.
Two Bb parents are crossed. This is the expected phenotype ration of dominant to recessive.
3:1
AA and aa both show the dominant trait. This shows that different genotypes can produce the same ____.
Fish and reptiles are strongly affected by this environmental factor because it influences their metabolism and growth.
Temperature
