Although iPSCs are functionally pluripotent, they are best at generating the cell types of the organ from which the parent somatic cell (naïve versus primed ESCs) originated. These data suggest that

One chromosome in a plant has the sequence A B C D E F, and another has the sequence M N O P Q R. A reciprocal translocation between these chromosomes produced the following arrangement: A B C P Q R on one chromosome and M N O D E F on the other. If an individual is heterozygous for this translocation, the consequence in meiosis will be as follows:    

A. The two normal chromosomes and-two translocated chromosomes pair separately

B. Half of gametes produced from this meiosis are non-viable as they have deletions and duplications

C. In one of the cross configurations called "horizontal segregation" all gametes having normal or translocated chromosomes will not survive

D. The gametes having normal chromosomes only survive while all gametes having translocated chromosomes are non-viable, hence the translocations are used as crossover suppressors

Which of the following combinations best describes the meiotic consequences for the translocation described above?

Fossil evidence indicates that several kinds of flightless dinosaurs possessed feathers. If some of these feather-bearing dinosaurs incubated clutches of eggs in carefully constructed nests, this might be evidence supporting the claim that

The recessive mutant allele that causes cystic fibrosis is much more frequent in Caucasians population than in other world populations. Some scientists believe heterozygotes must have had a survival advantage during plagues such as cholera that occasionally swept through this population. What concept does this illustrate?
