Gene- is a section of the DNA.
For each pair of chromosomes, the genes for a trait are in the same locations…alleles.

3. Genotype
Phenotype
The genotype environment influences the developmental opportunities of the phenotype.
I added this slide here from the ch 2 (part 1) slides

4. Dominant gene- a powerful allele whose characteristics are expressed in the phenotype...
Recessive gene- a weak allele whose characteristics are expressed in the phenotype...
Polygenic inheritance- the case in which a trait (phenotype) is determined by…
