genes
genotype
beautiful
The traits we inherit are determined by small segments of DNA called
genes
DNA
chromosomes
proteins
We get our features from our parents. The transfer of traits to offspring is called
dominant traits
genes
heredity
acquired traits
Traits that are always seen (brown eyes for example) are called
recessive traits
dominant traits
popular traits
male traits
These types of traits are only seen in the absence of dominant traits (for example blue eyes).
