Guided Notes: Modeling Sexual Reproduction
Big Idea: The main idea of this lesson is to explain why sexual reproduction leads to offspring with _________ _________.


Key Concepts:


_________ _________ - the fusion of an egg and a sperm

_________ _________ - the production of an identical genetic copy of a parent

_________ - variations of genes

_________ - a variant form of a gene

_________ _________ is the result of offspring receiving genetic information from two parents.

_________ _________ - traits such as eye color, hair color, and skin color which are inherited

_________ _________ - an allele that is dominant over another allele for a particular trait


Real World Examples:


Sarah has blue eyes, even though both her parents have brown eyes. This is because Sarah's parents each carry an _________ for blue eyes.

Hwan was born with a rare form of eye cancer called retinoblastoma (RB), even though neither of his parents had it. This is because genetic diseases like RB can _________ generations before appearing again.

Big Idea: The main idea of this lesson is to explain why sexual reproduction leads to offspring with genetic variation.

Key Concepts:

- Fertilization (fusion of an egg and a sperm)
- Asexual reproduction - the production of an identical genetic copy of a parent
- Alleles - variations of genes
- Allele - a variant form of a gene
- Genetic variation is the result of offspring receiving genetic information from two parents.
- Physical traits - traits such as eye color, hair color, and skin color which are inherited
- Dominant allele - an allele that is dominant over another allele for a particular trait

Real World Examples:

- Sarah has blue eyes, even though both her parents have brown eyes. This is because Sarah's parents each carry a recessive allele for blue eyes.
- Hwan was born with a rare form of eye cancer called retinoblastoma (RB), even though neither of his parents had it. This is because genetic diseases like RB can skip generations before appearing again.
