Chapter 6: Complex Patterns of Inheritance

Question 1

incomplete dominance

Answer 1

a condition which neither allele for a gene completely conceals the presence of another; it results in the immediate expression of a trait

Question 2

codominace

Answer 2

the condition by which both alleles for a trait are equally expressed in a heterozygote; both alleles are dominant

Question 3

heterozygous advantage

Answer 3

a survival benefit for individuals who inherit two different alleles of the same trait

Question 4

continuous variation

Answer 4

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

Question 5

polygenic trait

Answer 5

a trait that is controlled by more than one gene

Question 6

linked genes

Answer 6

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

Question 7

sex-linked trait

Answer 7

a trait controlled by genes of the X or Y chromosome

Question 8

bioinformatics

Answer 8

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

Question 9

genomics

Answer 9

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

Question 10

genetic profile

Answer 10

the complete genotype of an individual, including various mutations
