Presentation transcript:

Inheritance & Variance Traits Vocabulary

Allele One of a pair of genes that determine a specific trait

Chromosome A structure located in the nucleus of a cell, made of DNA, that contains the genetic information needed to carry out cell functions and make new cells.

Dominant Trait In a pair of alleles, the one that, if present, determines the trait

Genotype The set of genes carried by an organism

Heredity Passing of traits from one generation to another

Heterozygous Refers to having two different alleles for a specific gene

Homozygous Having identical pairs of genes for any given pair of hereditary characteristics.

Mutation A random change in a gene

Phenotype The physical appearance of an organism

Proteins A class of organic compounds found in living things that are essential for life

Punnett Square A table used to predict what traits offspring will have, based on what traits the parents have

Recessive Trait In a pair of alleles, the one that is masked if a dominant allele is present

Traits Trait is a characteristic you inherit or a distinguishing characteristic or feature.
