PPT-Sex determination systems and sex-linked inheritance

Sex determination Sex chromosome is determined at fertilization time Early stage fetus contains two ducts system Wolfian male Mullerian female Sexual difference starts in the . This presentation . builds on session 1 exploring patterns of inheritance. Patterns of inheritance. The objectives of this presentation are to:. Understand how genes are inherited. Understand the differences between the inheritance patterns associated with Autosomal dominant, Autosomal recessive, X-linked recessive and chromosomal abnormalities. Essential Question: . How are dominant and recessive sex-linked traits passed onto offspring?. Sex-linked traits are determined by genes on sex-chromosomes.. Most. sex-linked alleles (genes) are carried on the X chromosome. . Kyle . Stutts. . Sam . houston. state . university. Sex-Linked Characteristics. Objectives. Students will be able to:. Comprehend how inheritance plays a role in sex-linked genes. Explain the difference between sex- linked, limited, and influenced inheritance.  . Studying genetics . can be accomplished in part by . investigating the history of discoveries. that have lead to our . understanding of DNA and its role in gene expression and biological inheritance. 11.1 Basic Patterns of Human Inheritance. 11.2 Complex Patterns of Inheritance.
