Genetics

Genotype

• The lower case letter

• The alleles/letters of the characteristic

• The physical trait

• The capital letter

Phenotype

• Two different versions of the same gene

• The physical expression of a gene caused by the genotype

• The alleles/letter of the characteristic

• The same version of the same gene

Heterozygous

• Lowercase letter

• Both alleles are different. (One is dominant and one is recessive).

• Both alleles are the same (dominant or recessive).

• The capital letter

Homozygous

• The passing of traits or characteristics genetically

• Both alleles are the same (dominant or recessive).

• Both alleles are different

• A quality or characteristic

Dominant

• A form of a gene

• The allele/letter is lower case

• transferred from parent to offspring

• The allele/letter is capital

Recessive

• The allele/letter is lowercase

• The allele/letter is capital

• A set of characterisitcs

• The genetic make up of an organism

Polygenic Trait

• A characteristic inherited from two or more genes

• A segment of DNA that codes for a specific trait

• How traits are passed down

• the way organisms pass traits

Heredity

• Two or more alternative forms of a gene.

• In a heterozygote, one trait will conceal the presence of another trait for the same characteristic.

• refers to characteristics (traits) that are influenced by genes carried by sex chromosomes.

• The way organisms pass traits (characteristics) onto their offspring.

Allele

• alleles segregate randomly into gametes

• during gamete formation (sperm and egg cells), the alleles of different genes segregate independently of one another

• The thing in the chromosome that carries traits to the offspring.

• letter is dominant or recessive

Gene

• A physical expression of a gene caused by the genotype

• A segment of DNA that codes for a specific ant.

• An Austrailian monk born in 1822

• The genetic passing of a trait (characteristics)
