Mechanisms of Inheritance

Question 1

Have been inbred and have a homozygous genotype

Answer 1

true-breeding

Question 2

Examines inheritance of a single trait

Answer 2

monohybrid cross

Question 3

Diploid organisms have pairs of homologous chromosomes that have the same genes in the same order.
Different alleles may exist on each homolog.
Only one homolog is segregated into a gamete.

Answer 3

Law of segregation

Question 4

Cross done between individual with known phenotype and unknown genotype with a known genotype

Answer 4

Test cross

Question 5

Two genes on different chromosomes segregate their alleles independently during Meiosis. The inheritance of an allele of one gene does not influence the chance of inheriting an allele of another gene.

Answer 5

Law of Independent Assortment

Question 6

Examines the inheritance of two traits

Answer 6

dihybrid cross

Question 7

analysis allows the study of human genetics without controlled matings

Answer 7

pedigree

Question 8

two or more common phenotypes for a trait

Answer 8

polymorphism
