Q1. What is the difference between incomplete dominance and codominance?
A. In incomplete dominance, the dominant phenotype is expressed in heterozygotes. In codominance, both phenotypes are expressed in heterozygotes.
B. The phenotype reveals the genotype only in codominance.
C. In both types of inheritance, the heterozygotes express the phenotypes dictated by both alleles.
D. In codominance, both phenotypes are expressed in heterozygotes. In incomplete dominance, the heterozygote shows a phenotype that is intermediate between the two homozygotes.
Q2. Based on the following pedigree, with blood types provided (and ignoring the Bombay phenotype), what conclusions about paternity can be drawn?
A. This can be the father of either child.
B. This cannot be the father of either child.
C. This can be the father of the son but not the daughter.
D. This can be the father of the daughter but not the son.
Homework Answers
Q. 1 option B is the right answer.
Q. 2. Option A is the right answer.
For example, While a child could have the same blood type as one of his/her parents, it doesn't always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B. These two types are definitely different than parents' blood types. hey will match both parents
Please do thumbs up if you like the answer.

what is the difference between heterozygous and homozygous individuals
What is the difference between heterozygous and homozygous individuals? Homozygotes have one chromosome while heterozygotes have two similar chromosomes. The homozygote will express the dominant trait and the heterozygote will express the recessive trait. All of the gametes from a homozygote carry the same version of the gene while those of a heterozygote will differ. Heterozygotes carry two copies of a gene while homozygotes only carry one. When constructing a Punnett square, the symbols on the outside of the boxes...

AL11 Activity 4: Multiple alleles with Codominance 1. Some traits in a population are determined by multiple alleles. For example, there are three alleles for Mood type in the human population (type A), P type B). and i lypeo). Different combinations of these alleles (each individual can inherit only two alleles) produce the four different blood types (phenotypes) that we are familiar with Based upon the symbols alone, what can you predict about the relationships between each of the following...

1) What is the molecular basis of dominant and recessive alleles (for complete dominance; ignore incomplete dominance, epistasis, etc.)? To answer this question, consider the following: a) If alleles are copies of the same gene, why are two types of alleles? What differentiates a dominant allele from a recessive allele (at the molecular level)? Be specific (base pairs, transcription/translation method, protein produced, etc.) b) Why is the phenotype determined by the dominant allele in heterozygous genotype? Be specific. c) What...

True or False: there can be carriers for conditions that are inherited through dominant alleles, as well as those inherited through recessive alleles. Select one: True False Which of the following is NOT true regarding dominance/recessiveness relationships of alleles? Select one: O a. The trait of the recessive allele can be expressed but is not evident in a heterozygote. O b. Dominant alleles are not necessarily more common in a population than recessive alleles. O c. They range from complete...

1. In humans the allele for A type (IA) blood and B type blood (IB)show co-dominance, so that a person with both alleles has blood type AB (phenotype). Both A and B alleles are dominate to the allele for O (i). A person with an allele for type A blood and an allele for type o blood marries someone with an allele for type B blood and an allele for type o blood. List the types of offspring they could have and...
