Organisms can have different _______ in their cells for a particular _______
Organisms can have different proteins in their cells for a particular feature
______ are instructions for ______.
Genes are instructions for proteins.
Organisms _______ their genes through sexual reproduction.
Organisms inherit their genes through sexual reproduction.
When a male and a female reproductive cell combine to create offspring.
Fertilization
Differences in the ______of a protein molecule affect how they connect to other protein molecules. This can result in different ______.
Differences in the structure of a protein molecule affect how they connect to other protein molecules. This can result in different traits.
An organism has _____ copies of a _____ for each feature.
An organism has two copies of a gene for each feature.
Each parent ________ passes on one of its two copies of each gene to its offspring. Each offspring, therefore, receives _____ copies of each gene, one from each parent.
Each parent randomly passes on one of its two copies of each gene to its offspring. Each offspring, therefore, receives two copies of each gene, one from each parent.
A specific form of a gene that provides instructions for making a particular protein molecule
Gene Version
The _______ of molecules determines how they _____ at a molecular scale, which determines the properties of the objects they make up
The structure of molecules determines how they function at a molecular scale, which determines the properties of the objects they make up.
If the gene copies are the same the organism is _______
If the gene copies are the same the organism is homozyogus.
Fertilization is _____, which can lead to a different combination of _______ from the parents, and a ____ that no one else in the family has.
Fertilization is random, which can lead to a different combination of genes from the parents and a trait that no one else in the family has.
to receive genes from a parent
Inherit
The function of a protein molecule depends on its _______ and how it interacts with other ______ molecules.
The function of a protein molecule depends on its structure and how it interacts with other protein molecules.
If the gene copies are different the organism is _______
If the gene copies are different the organism is heterozygous.
Through sexual reproduction, each offspring can inherit a different _______ of gene versions. Therefore, siblings can have _______ traits from each other and even from their parents.
Through sexual reproduction, each offspring can inherit a different combination of gene versions. Therefore, siblings can have different traits from each other and even from their parents.
