ANSI 3423 Final UPDATED Exam
Questions and CORRECT Answers
paternal - Correct Answer- gene where allele from the father is turned off
Genetics - Correct Answer- the science that deals with the study of heredity and variation
Heredity - Correct Answer- the transmission of traits from one generation to the next
Variation - Correct Answer- similarities and differences
quantitative genetics - Correct Answer- study of measurable traits
population genetics - Correct Answer- study of traits in a group of individuals
cytogenetics - Correct Answer- study of chromosomes
molecular genetics - Correct Answer- molecular function and structure of genes
Mendelian Genetics - Correct Answer- transmission of genes and traits from generation to
generation
genome - Correct Answer- total genetic component of an organism
DNA - Correct Answer- genetic material of living organisms - mode of inheritance
chromosome - Correct Answer- contains the genetic material: DNA and RNA
chromatin - Correct Answer- it the chromosomal material in its decondensed, threadlike state

threadlike state.
cytokinesis - Correct Answer- division of the cytoplasm
meiosis - Correct Answer- halves the number of chromosomes
metaphase I - Correct Answer- aligned pairs of chromosomes move to the equator of the
dividing cell
anaphase I - Correct Answer- members of homologous pairs of chromosomes separate from
each other, move to opposite poles of the cell
telophase I - Correct Answer- Cytoplasm divides, 2 daughter cells are formed
