- The Effect of Multiple Alleles A gene can have many different alleles within a population. A single organism can only have two alleles because it receives one from each of its p…

- Different Versions of Alleles Many genes have more than two alleles (versions of the gene). This means that more than two forms of the allele exist in a species. Blood type is a…

- If a mom has a genotype IAIAI^A I^AIAIA and the father has a genotype of IBIBI^B I^BIBIB, what genotype do all of the children have?
- Although there are many different alleles for a certain gene, an organism can only express 000‾\underline{\phantom{000}}000 at a time.
- Fill in the blank: There can be more than two alleles for one gene in 000‾\underline{\phantom{000}}000. There may be more than one possible answer.
- Suppose that there are 6 different possible phenotypes for one trait. Which of the following inheritance patterns would best explain this phenomenon?
- 3 alleles exist for blood type (A, B, and O). What type of inheritance pattern does blood type have?
- How many different genotypes would you expect for a trait that is controlled by 4 alleles?
- Which of the following is true about multiple allele genes?
- If for some trait T, one parent is genotype Ta^{a}aTb^{b}b and the other parent is genotype Tc^{c}cTd^{d}d, what are the possible trait combinations in their offspring? Check al…
- If for some trait T, one parent is genotype Ta^{a}aTb^{b}b and the other parent is genotype Tc^{c}cTd^{d}d, which is NOT a possible trait combination in their offspring?
- Which of the following is true about multiple allele traits?
- If you have blood type AB and you marry someone whose genotype is IB^{B}BIO^{O}O, which is blood type is NOT possible for your children?
- Gene A codes for color in a rare tropical flower. There are 3 possible alleles: X codes for purple color, Y codes for yellow, and Z codes for white. Z is dominant to Y, and X is…
- Which of the following is true regarding polygenic traits and multiple allele traits?
- Which choice best represents a multiple allele trait?
- For which of the following would you most likely expect to find multiple alleles?
- Imagine this situation: Two guys are fighting over which one of them is the father of a new born baby. For some reason, the only evidence they have is blood type. The baby has t…
- What is a benefit of multiple alleles?
- Blood type is determined by the alleles A, B, and O. When a person has the genotype AB, the alleles have a codominant relationship. What distinguishes the inheritance pattern of…
- How are traits with multiple alleles similar to polygenic traits?
- What causes multiple alleles to arise for certain genes?
