Instructions
Play through this interactive game to learn about Variation of Inherited Traits. Suitable for Grade 6, Grade 7, Grade 8.
Main Concepts
In sexual reproduction, the offspring are genetically distinct from their parents.
Genes are located on the chromosomes inside of the nucleus of a cell.
A Punnett square is a chart that shows the possible genotype combinations in offspring from two parents.
In sexual reproduction, the offspring inherits half of its genetic material from its mother and half from its father.
In humans, the sex chromosomes are called X and Y.
Incomplete dominance occurs in heterozygotes when neither allele dominates and there is instead a blending of the two alleles.
Phenotype describes the observable traits that an organism expresses from its genetic makeup.
Genes are responsible for the specific traits of an individual.
Heredity is the passage of genetic information from one generation to the next.
Some alleles are dominant while others are recessive.
The different varieties of a particular gene are called alleles.
Traits controlled by genes on sex chromosomes are called sex-linked traits.
Humans have 23 pairs of chromosomes, totaling 46.
Genotype is the genetic makeup of a living organism and depends on which alleles the organism inherited from its parent(s).
Homozygous means that an organism contains the same alleles of a gene on their chromosomes.
Codominance occurs in heterozygotes when both alleles dominate and are both expressed in the offspring.
Heterozygous means that an organism contains different alleles of a gene on their chromosomes.
Homologous chromosomes have the same type of gene at the same location on the chromosome.
Sexual reproduction improves the genetic variation of a species.
In asexual reproduction, the offspring are genetically identical to their parents.
Discussion Questions
Before the Game
What traits do you share with someone in your family? What are genes? What is heredity?
After the Game
What does Punnett Square show you? What is the difference between heterozygous and homozygous? How many pairs of chromosomes do humans have? What are the varieties of a gene called?
