GCD 3022 Exam 1 Spring 2026 Questions With Complete
Solutions
(# of recombinant offspring)/(total # of offspring) x100 =
Correct Answers Map distance
A gene is repositioned in a way that alters its gene
expression Correct Answers Position effect
A modification occurs to a nuclear gene or chromosome
that alters gene expression, the modification/expression is
not permanently changed over the course of many generations
Correct Answers Epigenetic inheritance
A segment that has been flipped to the opposite orientation
Correct Answers Inversion
Allele that has the potential to cause the death of an organism
Correct Answers Lethal allele
Alleles of different genes are not linked Correct Answers Law
of Independent Assortment
Alleles that have been altered by mutation, often defective in
their ability to express a functional protein or RNA Correct
Answers Mutant alleles
An inversion that doesn't go around the centromere Correct
Answers Paracentric
, An inversion that goes around the centromere Correct Answers
Pericentric
An organized representation of the
chromosomes within a cell Correct Answers Karyotype
Chromosomes (one from mom, one from dad) nearly identical
but with different alleles Correct Answers Homologous pair
Chromosomes are called ______, containing a group of genes
that are linked together Correct Answers Linkage groups
Consists of two or more genes that are derived from the same
ancestral gene Correct Answers Gene family

Determines how close the observed data are
to those predicted from a hypothesis Correct Answers Chi
Square Test
Differences between members of the same species or those of
different species Correct Answers Genetic variation
Dosage compensation is also called... Correct Answers X-
