Chromosomal Inheritance

My AP Biology Thoughts

Welcome to My AP Biology Thoughts podcast, my name is Stefanie Ribecca and I am your host for episode # 104 called Unit 5 Heredity: Chromosomal Inheritance. Today we will be discussing how inheritance occurs in the chromosomal level.

Segment 1: Introduction to Chromosomal Inheritance

• Chromosomal inheritance is an extension of Mendelian genetics.
• Chromosomes contain DNA which carry the genetic information that code for proteins.
• Chromosomes are found in pairs, and increase genetic variation during meiosis.

Segment 2: More About Chromosomal Inheritance

• During meiosis, non sister chromatids in homologous pairs exchange information during crossing over.
• Certain genes may be close together on the chromosome and may appear to be inherited together.

Segment 3: Connection to the Course

• Chromosomal inheritance allows for a combination of traits from both parents.
• Genetic diversity from chromosomal inheritance allows individuals in a population to adapt to the environment.
