the trait that shows
recessive trait
the trait that doesn't show
the trait that shows
hybrid cross
two purebred parents

the study of how traits are passed from one generation to the next
the study of humans
the study of organisms
Punnett square

the answer to all of life's questions
Circle the dominant allele
Circle the recessive allele
What is a phenotype
the physical characteristics of an organism
the hidden characteristics of an organism
What is a genotype
the hidden characteristics of an organism
the trait that shows
Heterozygous: two different alleles
True
False
physical characteristics of an organism
(a)
genetic makeup of an organism
(a)
incomplete dominance
both alleles are blended together
both alleles are there, but separated
another name for clone
codominance
both phenotypes are blended together
we see both phenotypes, but they aren't blended
when 2 or more genes interact to control a single character
polygenic inheritance
when 2 or more genes interact to control a single character
belief in multiple gods
artificial selection
when we purposely alter the ratio of alleles to favor one phenotype
the change of alleles
genetic drift
the change in ratios of alleles in a population over time
an inherited trait that helps the animal survive and reproduce
favoring a certain phenotype
Which one is not true?
trait: specific characteristic
purebred: always produce descendants with the same trait
hybrid cross: a cross between a hybrid and a purebred
homozygous: same alleles
What are the Principles of Heredity?
In a cross of purebred parents, all offspring will show the dominant trait.
For any one character, the 2 alleles will separate and combine to determine offspring trait.
A parent passed each allele to its offspring independently of all other alleles.
All of the above
