Heredity and Natural Selection Overview

Heredity

Transmission of genetic traits from parents to offspring.

Gregor Mendel

Scientist known for foundational genetics studies.

Punnett Squares

Tools for predicting offspring genetic traits.

Asexual Reproduction

Offspring produced from a single parent.

Sexual Reproduction

Involves sperm and egg to form zygote.

Zygote

Fertilized egg resulting from sperm and egg fusion.

Alleles

Different forms of a gene found in chromosomes.

Genetic Mutation

Change in DNA sequence impacting traits.

Natural Selection

Process where organisms better adapted survive.

Selective Breeding

Choosing parents to produce desired traits in offspring.

Cloning

Creating an exact genetic copy of an organism.

Camouflage

Adaptation that helps organisms blend into environment.

Dwarfism Trait

Genetic characteristic resulting in shorter stature.

Identical Cells

Cells that are genetically the same as parent.

Cricket Communication

Use of sound for mating and reproduction.

Fossil Evidence

Remains indicating historical existence of species.

Shark Adaptations

Physical traits enhancing survival in specific environments.

Black Spots

Inherited trait observed in lady beetles.

Offspring Variety

Genetic diversity resulting from sexual reproduction.

Environmental Suitability

How well an organism's traits fit its habitat.
