Variations of homologous genes that result in differences in structure and function are
alleles
The las of segregation states that
genes sperate from each other during gamete formation so that each sperm and egg receive only one allele from each pair.
Cystic fibrosis is a genetic disorder that results from the inherence of two recessive alleles. What is the chance that a child will inherit the disorder if one parent is heterozygous for this gene and one parent has cystic fibrosis?
50%
In polygenic inheritance,
multiple alleles and genes contribute to a phenotype.
When a piece of chromosome breaks off ad reattached at another site on the same or another chromes, this is called
translocation
Manipulation of genetic makeup of cells or whole organisms is known as
genetic engineering
Bacterial __________ DNA can be removed from the bacterium, modified by adding a gene of interest, and then reinserted into the bacterium to be replicated.
plasmid
When sequencing DNA, how are special nucleotides marked so that they can be identified at the end of the process?
They are labeled with florescent marker.
Organisms that carry genes from other species are referred to as
transgenic
A small amount go DNA was located at a crime scene. Which of the following techniques is most likely to be used to amplify the DNA so it can be identified more accurately?
