Master the 7 pillars of school success that I have learned from 25 years of teaching.

In genetics traits are features and characteristics that can be passed from one generation to another.
• Examples include skin color,cleft chin, blood type, and height.
• Traits of dogs would include, length of tail, shape of ears and color.
• Each of these factors can be passed genetically to another generation.
• Each trait has different forms of the same trait.
• For example, everyone has a nose, but the nose can have many different shapes.
• The different forms of the same trait are called alleles.
• Traits can also be dominant or recessive
• Each individual has two alleles for each gene, one coming from mom and the other from dad.
• A dominant gene can be expressed even if only one copy of the gene is present.
• A dominant trait can be homozygous which means it has two of the same alleles, or heterozygous which means it has two different alleles.
• A recessive trait will only be expressed if an individual homozygous recessive.
• Phenotype is the physical expression of a trait.

See which of these traits that you have.
• Attached earlobes vs free earlobes
• Straight hair line vs. widows peak
• Cleft chin vs no cleft chin
• Dimples vs no dimples
• Freckles vs no freckles
• Tongue roll vs no tongue roll
• Longer 2nd toe vs shorter 2nd toe

In summary, a trait is a feature that can be passed from one generation to the next.
