Understanding Incomplete Dominance and Genetic Traits in Biology

This article explores the concepts of incomplete dominance and the roles of alleles in genetics. It defines essential terms such as genotype and phenotype, illustrating how traits are expressed in organisms. Incomplete dominance is showcased through examples, such as the blending of a white and red flower yielding a pink flower. The differences between heterozygous and homozygous alleles are also discussed, providing a comprehensive overview of how genetic traits are inherited and displayed.

  2. Complete dominants- both alleles are showing no blending (year published – 2010) Alleles- different versions of a gene (dominant vs. recessive) (year published – 2010) Genes- particular region of DNA controlling specific trait (year published – 2010) Incomplete dominants- the alleles are blended ex. A white flower and a red flower = a pink flower (year published – 2010) DefinitionsBy: Bright Storm 2

  3. Phenotype- an organisms actual physical trait (can be seen) cased by genotype (year published –2010) Definition continuedBy: Bright Storm 2

  4. Genotype- 25%RR 50%RW 25%WW Phenotype- 25% Red flower 50% Pink flower 25% White flower + = Definition By: W.R McCommom

  5. Heterozygous- cell with 2 different alleles in the position of homozygous chromosomes Homozygous- reveres to having identical alleles for a single trait Definition By: American Heritage
