Chapter 6 Complex Patterns of Inheritance (Defs.)

Question 1

A condition in which neither allele for a gene completely conceals the presence of the other; it results in intermediate expression of a trait.

Answer 1

Incomplete dominance

Question 2

The condition in which both alleles for a trait are equally expressed in a heterozygote; both alleles are dominant.

Answer 2

Codominance

Question 3

A survival benefit for individuals who inherit two different alleles for the same trait.

Answer 3

Heterozygous advantage

Question 4

A range of variation in one trait resulting from the activity of many genes.

Answer 4

Continuous varitation

Question 4

A trait that is controlled by more than one gene.

Answer 4

Polygenic trait

Question 5

Genes that are on the same chromosome and that tend to be inherited together.

Answer 5

Linked genes

Question 6

A trait controlled by genes on the X or the Y chromosome.

Answer 6

Sex-linked trait

Question 7

A field of study that deals with using computer technology to create and analyze large databases of information.

Answer 7

Bioinformatics

Question 8

The study of genomes and the complex interactions of genes that result in phenotypes.

Answer 8

Genomics

Question 9

The complete genotype of an individual, including various mutations.

Answer 9

Genetic profile
