Mendel’s Punnett Squares. Genes and Alleles Gene: Place on chromosome and determines certain trait Allele: variation of that trait Ex: Gene: Eye color.
OBJECTIVE: SWBAT define key terms used in genetics IOT explain the process of biological inheritance QUESTION: How do we know which genes we will inherit.
POINT > Review some genetics vocabulary POINT > Define genotype and phenotype POINT > Define homozygous and heterozygous POINT > Use a Punnett Square.
Genes Observable traits are the result of genes. – Genes are found on the chromosomes in our cells – Each observable trait is determined by two genes,

Genetics Vocabulary You will be using this vocabulary to complete the “project board assignment”

Physical traits; physical appearance What you can see with your eyes Phenotype Physical traits; physical appearance What you can see with your eyes

Genotypes What is expressed on the gene; genetic combinations Genes are on chromosomes (created in protein synthesis) Represented by the two letters in each box of a Punnett square

Allele Type of gene; form of a gene Each individual letter is an allele Example: Gene: Hair Color Gene: Flower Color Alleles: Alleles: Brown Purple Blonde White Black Pink Red

Dominant Powerful, strong, overshadows the recessive allele We represent dominant alleles with a capital letter

Recessive Weak, easily masked(covered up); not seen when a dominant allele is present We represent recessive alleles with lower case letters

Homozygous Homo = same Same alleles Ex. BB, HH, aa, kk, gg

Heterozygous Hetero = different Different alleles Bb, Gg, Ff. Tt
