Ch 1 lessons 1-3

Asexual reproduction

• Produces offspring that are not identical to the parents

• Increases genetic variation

• Does not increase genetic variation

• requires two parents

NGSS.MS-LS3-2

Sexual reproduction

• Only requires one parent

• Increases genetic variation

• Decreases genetic variation

• Offspring are identical to the parent

NGSS.HS-LS4-2

NGSS.HS-LS4-4

The process of a sperm and egg cell fusing to form a new cell is called

• asexual reproduction

• Fusion

• Fission

• Fertilization

A specific characteristic that an organism can pass to its offspring through its genes is called a

• Allele

• Trait

• Mutation

• gene

NGSS.HS-LS3-2

A sequence of DNA that determines a trait and is passed from parent to offspring is a

• trait

• gene

• mutation

• codon

Tags

NGSS.HS-LS3-1

The process by which an offspring receives genes from its parents

• Inheritance

• mutations

• cell replication

• transcription

NGSS.HS-LS3-1

NGSS.HS-LS3-2

An ____________________ is a different form of the same gene

• codon

• trait

• gene

• allele

When this allele is present it will show up in the offspring

• recessive

• dominant

Tags

NGSS.HS-LS3-1

When a dominant allele and recessive allele are inherited and expressed together. This is an intermediate form of both traits (Ex: Red and White flowers having offspring that are pink)

• Incomplete dominance

• Codominance

• Polygenic Inheritance

• Mutations

Both Alleles are expressed at the same time

• Polygenic Inheriance

• Codominance

• Incomplete dominance
