A mutation in a gene often results in a reduction of the product of that gene. The term for this type of mutation is:

The phenomenon in which one crossover decreases the likelihood of crossovers in nearby regions is called ________________.

How many kinds of gametes will be expected from genotype: Pp Cc TT Rr

Early in the twentieth century, Walter Sutton and Theodor Boveri noted that the behavior of chromosomes during meiosis is identical to the behavior of genes during gamete formation. They proposed that genes are carried on chromosomes, which led to the basis of the:

Multiple mutations that are found to be present in a single gene are said to belong to the same ___________________  group.

Areas of low density in a CT image appear black.  

The beam filter next to the xray tube is a prefilter called bow-tie filter.  It removes

CT scanners use these to protect the patient and limit the beam to the size of the detector array that is active during data acquisition.  

This is the mounted framework that surrounds the patient and houses xray tube.
