Ch 12 Heredity: Punnett Squares; 12.3 Active Reading

-Think & write/warm-up (review)...

 List five characteristics that are passed on in families. 

Also, name one characteristic that is inherited but that 

may also be influenced by behavior or environment. 

Why It Matters...

Your genetic makeup influences your appearance, your abilities, and your health. We now know that many human traits have their origins in genes. As we come to understand how traits are inherited, we can use this information to better our lives.


Ch 12: Origins of Hereditary Science 

Learning Objective: I can explain how genetic traits are 

passed from one generation to another.


Vocabulary terms:

allele - different variations of a gene

dominant - an allele that is fully expressed when present

recessive - an allele that is expressed only in the absence of a dominant allele

genotype - combinations of alleles in an individual

phenotype - physical traits that result from genotype

homozygous - two identical alleles of a gene

heterozygous - two different alleles of a gene
