Target Language or Knowledge:

allele the 2 versions of a gene (one from each parent) cladogram model that demonstrates evolutionary relationships among organisms DNA (deoxyribonucleic acid) makes up our 23 pairs of chromosomes in each cell genome in cells and carries identical genetic information unique to you heterozygous two different alleles at a specific locus on a pair of chromosomes phenotype the physical characteristics and expression seen in an organism recessive less influential and represented with a lowercase letter ex: b variation established a s a result of sexual reproduction- range of difference between traits of a feature in the individual common ancestor a person from the past that is related to all the people or organisms in the family group dominant more influential and represented with an UPPER CASE LETTER ex: B genes make up the DNA code for proteins that are responsible for organism's traits (stored in nucleus of cell) genotype the 2 alleles for each trait or feature ex: AA, Aa, or aa (genetic makeup of a set of genes) homozygous two of the same alleles at a specific locus on a pair of chromosomes population made os same species that can adapt or change gradually over time along with their surroundings ( or can stay the same) descendant organism that is related to an organism that lived earlier
