Alleles — Definition & Role in Inheritance
Read this topicExplanations 4
- What Is an Allele? They are different forms of a gene. They code for different variations of the same trait. Green, blue, and brown eyes are alleles of the gene for eye color. C…

- The Difference Between a Gene and an Allele Imagine that you're a scientist working with frogs. You have two frogs: one green and one blue. If you wanted to describe these frogs…

- Gene vs. Allele In a basic allele relationship, one dominant allele and one recessive allele. Only the dominant one will be physically expressed. However, keep in mind that this…

- Corgis come in two coat colors, tri-color (black, red, and white) and fawn (red and white). Most corgis are fawn colored. What does this imply about the fawn trait?
- What is an allele?
- FIll in the blank: If an organism is heterozygous for a trait, the dominant allele is woahwha‾\underline{\phantom{woahwha}}woahwha and the recessive is woahwha‾\underline{\phan…
- A certain gene codes for enzyme X. The enzyme is part of a complex chemical pathway. Individuals homozygous for the recessive allele of this gene cannot complete the chemical pa…

- What would the allele pair of gene D be classified as?
- What would the allele pair of gene C be classified as?
- Suppose the apple above represents an allele of a certain gene. Which of the following would be a different allele of the same gene?
- Piada has brown hair, but her friend Reginald has blond hair. Thinking about genetics, why would their hair color be different?

- Which of the following is an example of an allele?
- The picture above shows two homologous chromosomes. Which of the following is an allele of the gene labeled A?
- If there is a gene called 'color', which of the following could be its allele?
- A sequence for a certain gene is shown for two homologous chromosomes. Why are the sequences not identical?
- What does it mean when two homologous chromosomes have identical sequences except for a segment of 3 DNA bases?
- During which of the following processes can a new allele be created? Hint: How do alleles of the same gene differ, and what kind of error can cause this?
- In what case would two people share 50% or more of their alleles?
- You meet a complete stranger and find out that you share all of your genes, but almost none of your alleles. How is this possible?
- What is an example of multiple genetic alleles influencing one set of phenotypes?
