UNIT FIVE: GENETICS: EXPLORING HEREDITY

UNIT OBJECTIVES

UPON COMPLETION OF THIS UNIT, THE STUDENT WILL BE ABLE TO:

¨ DEFINE CORE TERMINOLOGY.

¨ DESCRIBE THE EXPERIMENTS OF GREGOR MENDEL.

¨ UNDERSTAND HOW SEGREGATION OF ALLELES OCCURS.

¨ CONDUCT MONOHYBRID, DIHYBRID CROSSES (PUNNET SQUARES).

¨ MAKE PREDICTIONS OF GENETIC CROSSES USING THE RULES OF PROBABILITY.

¨ EXPLAIN THE RELATIONSHIP BETWEEN DNA, CHROMOSOMES AND GENES.

¨ DESCRIBE THE CHROMOSOMAL THEORY OF HEREDITY.

¨ EXPLAIN HOW GENE LINKAGE, AND CROSSING OVER AFFECT INHERITED TRAITS.

¨ DESCRIBE THE SEX DETERMINATION IN HUMANS.

¨ EXPLAIN HOW HUMAN HEREDITY DIFFERS FROM MENDEL’S WORK.

¨ DISCUSS THE VARIOUS TYPES OF MUTATIONS.

¨ DESCRIBE THE TYPES OF INCOMPLETE DOMINANCE.

¨ PREDICT, USING PUNNET SQUARES, HOW SAMPLE TRAITS ARE INHERITED.

¨ SOLVE GENETIC PROBLEMS INVOLVING HEREDITY.

¨ DISTINGUISH BETWEEN AUTOSOMES AND SEX CHROMOSOMES.

¨ EXPLAIN INHERITANCE VIA MULTIPLE ALLELES EX. BLOOD TYPES.

¨ EXPLAIN THE GENETIC REASONS FOR SOME OF THE MAJOR GENETIC DISORDERS FOUND IN HUMANS, AS WELL AS INHERITANCE PATTERNS.

¨ CONDUCT A LITERATURE SEARCH ON ONE GENETIC DISORDER. OBTAIN THREE ARTICLES PERTAINING TO THE DISORDER. WRITE ANNOTATED BIBLIOGRAPHIES FOR THE ARTICLES AND WRITE A SUMMARY OF YOUR RESEARCH.

¨ DISCUSS SOME OF THE ISSUES INVOLVING SELECTIVE BREEDING.

¨ NAME AND DISCUSS SOME OF THE TECHNIQUES USED IN GENETIC ENGINEERING AND BIOTECHNOLOGY.
