People who breed plants like these want all plants to be identical. The plants are bred for their appearance, and they must be consistent in appearance to meet customers’ expectations. Using __________ __________ they can be sure to get identical plants because the genes of the offspring will be identical to the parent.
Guided Notes: Asexual and Sexual Reproduction
Big Idea: The main idea of this lesson is to compare _________ and _________ reproduction.


Key Concepts:


_________ _________ - the production of offspring from one parent

_________ _________ - the production of offspring from two parents

_________ - egg or sperm cells

Sexual reproduction creates more _________ _________.




Real World Examples:


The sandhill crane reproduces sexually, which gives its offspring greater _________ _________ since it receives genetic information from two parents instead of one.

The starfish can reproduce asexually through _________, which does not require gametes to combine and can result in more offspring.








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.

People who breed plants like these want all plants to be identical. The plants are bred for their appearance, and they must be consistent in appearance to meet customers’ expectations. Using asexual reproduction they can be sure to get identical plants because the genes of the offspring will be identical to the parent.

Guided Notes: Asexual and Sexual Reproduction
Big Idea: The main idea of this lesson is to compare asexual and sexual reproduction.

Key Concepts:

- Asexual reproduction - the production of offspring from one parent
- Sexual reproduction - the production of offspring from two parents
- Gametes - egg or sperm cells
- Sexual reproduction creates more genetic variation.

Real World Examples:

- The sandhill crane reproduces sexually, which gives its offspring greater genetic variation since it receives genetic information from two parents instead of one.
- The starfish can reproduce asexually through fragmentation, which does not require gametes to combine and can result in more offspring.

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

Key Concepts:

- Fertilization - the fusion of an egg and a sperm
- Asexual reproduction - the production of an identical genetic copy of a parent
- Genetic variation - variations of genes
- Allele - a variant form of a gene
- Genetic variation is the result of offspring receiving genetic information from two parents.
- Inherited 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.
