A version of a gene
Allele
The reproductive process involving two parents whose genetic material is combined to produce a new organism different from themselves
Sexual Reproduction
If an offspring is produced through sexual reproduction, the offspring’s genetic material is always
A blend of the genetic material from both its parents.
Humans inherit traits from their...
Parents
A single, highly organized and structured piece of DNA.
Chromosome
A characteristic that is passed from parent to offspring
Inherited Trait
What color fur is dominant based off this Punnett Square?
Agouti fur
How are traits inherited by offspring?
Parents each pass down one allele for each trait, and the allele that is dominant will be expressed
The basic physical and functional unit of heredity made up of DNA
Gene
Product of reproduction; a new organism produced by one or more parents
Offspring
Any individual offspring produced through asexual reproduction always has what kind of genetic information when compared to parents?
Genetically identical to its parent
Starfish can reproduce both sexually and asexually. What would be the most reliable way to determine if a group of offspring of the starfish was produced through sexual or asexual reproduction?
Genetic variation of their characteristics can be examined
The reproductive process that involves one parent and produces offspring identical to the parent
Asexual Reproduction
A tool used to analyze the possible allele combinations of the offspring between two individuals
Punnett Square
Two brown-eyed parents can produce a child with blue eyes. How is this possible?
Both parents carry the recessive blue eye gene that is passed on to the offspring
In sexually reproducing organisms, each parent contributes _________of the genes acquired by the offspring
Half
The variety of gene combinations that exist within a population
Genetic Variation
The occurrence of an organism, trait, or gene in more than one form
Variation
Why do variations of inherited traits between parent and offspring occur?
Variations happen due to genetic differences that result from the chromosomes that are inherited from their parents
Two children born to the same parents have many similarities, but overall, they have different appearances. How is this possible?
Because offspring inherit an allele for every trait from each parent, there are multiple combinations of traits that each child can inherit
