The table below shows the genotypes that result in four different blood types in humans. 
Based on the information in the table, which of the following describes alleles IA and IB?
The IA and IB alleles show sex linkage.
The IA allele is recessive to the IB allele.
The IA allele is dominant to the IB allele.
The IA and IB alleles show codominance.
Why do siblings with the same biological parents sometimes inherit different combinations, or a variation of traits, such as eye color, hair type, or height?
Independent assortment
Sex linkage
Dominance
Gene linkage
A male and female child have three copies of chromosome 18. Although both parents are unaffected, their doctor claims that the disorder associated with having an extra chromosome 18 is the result of a chromosomal mutation in cells that carry inherited material. Which argument supports this claim?
A mutation occurred when crossing over caused chromosome 18 to be replicated twice during meiosis, allowing one parent to donate two copies of chromosome 18 to the child.
A nondisjunction mutation was caused by the improper separation of the genetic material during meiosis, allowing the gamete of one parent to donate two copies of chromosome 18 to the child.
A substitution mutation during replication allowed the genetic material of chromosome 18 to replace the genetic material of a nearby chromosome, causing the child to have three copies of chromosome 18.
An deletion mutation during replication allowed the genetic material of chromosome 18 to be inserted into the genetic material of another chromosome, causing three copies of chromosome 18.

The group constructs multiple explanations for their conclusion. Choose the best explanation that uses evidence from the model.
The chromosomes line up independently of one another in metaphase I and metaphase II which leads to each final daughter cell having different chromosomes.
The chromosomes line up in the middle of the cell in a specific order which leads each daughter cell to have different chromosomes.
In both metaphase I and metaphase II the chromosomes exchange genetic information which leads to different chromosome combinations in the final daughter cells.
In both metaphase I and metaphase II the sister chromatids are splitting up to create different combinations in the final daughter cells.
