GENETICS AND SOCIETY

Traditional agriculture involves the controlled breeding of plants and animals with specific combinations of useful or desirable inherited phenotypes.

HUMAN GENETICS

______numerals are used to indicate different______. ______numerals are used to indicatedifferent individuals within each ______.

______inheritance refers to traits—dominant andrecessive—that are coded for by genes on ______(chromosome other than a sex chromosome).

Autosomal______traits tend to skip one or more______in pedigrees.

____-linked recessive traits canskip generations, but some of the ______in thatgeneration must be carriers if the trait appears in a latergeneration. X-linked ______traits can occur in the______children of ______who are ______or have thetrait themselves. Female children may be ______, butwill only have the disease if their ______has it and theirmother is a carrier or also has it, which is rare.

The way that a female can have hemophilia is if her ______has thedisease and her ______is a carrier or has the disease.

HUMAN GENETIC ANALYSIS

______helps geneticists develop new ways to identify people who are at risk of developing particular genetic conditions or of passing these conditions to their children. This process is called ______screening.

Some examples of genetic screening could be for:

______disease, which the alleles are present on chromosome number 4 and is a degenerative ______disease that results in loss of muscle control and dementia.

A disease linked to chromosome 15 is described in patient’s that have a disorder within the ______tissues, causing ______in the heart, blood vessels, and skeleton. This is called ______syndrome.

Those individuals who have problems accepting the condition can seek help via a ______. These counselors can estimate the risk of inheriting a particular genetic condition and provide information on ______of the genetic condition, provide available treatments and other information and most importantly provide ______support.
