These are the building blocks of DNA.
What are nucleotides?
This is a trait passed from parents to offspring.
What is an inherited trait?
This term describes an organism with two identical alleles
What is homozygous?
This is a permanent change in DNA.
What is a mutation?
This is the use of technology and living organisms to produce useful products.
What is biotechnology?
These two nitrogen bases pair together in DNA besides cytosine and guanine.
What are adenine and thymine?
These are different forms of the same gene.
What are alleles?
This scientist discovered the basic principles of inheritance using pea plants
Who is Gregor Mendel?
This is a trait that helps an organism survive in its environment.
What is an adaptation?
This type of inheritance occurs when one allele completely masks the other
What is complete dominance?
This is the complete DNA sequence of an organism
What is a genome?
This is the physical appearance of a trait.
What is a phenotype?
This term describes an organism with two different alleles.
What is heterozygous?
This process causes populations to change over generations because individuals with useful traits survive and reproduce.
What is natural selection?
This type of inheritance occurs when a red snapdragon crossed with a white snapdragon produces pink flowers.
What is incomplete dominance?
This type of RNA carries genetic instructions from DNA to the ribosome.
What is mRNA?
This is the allele combination of an organism
What is genotype?
This type of allele is expressed only when two copies are present.
What is a recessive allele?
These environmental factors influence survival, such as predators, competition, and disease.
What is selective pressure?
These three components make up a nucleotide.
What are a phosphate group, a sugar, and a nitrogenous base?
The triplet of nitrogen bases on mRNA that codes for an amino acid.
What are codons?
This tool is used to predict offspring traits in genetics
What is a Punnett square?
This type of cross studies one trait at a time
What is a monohybrid cross?
This term describes when one species split into two new species over time
What is speciation?
This type of inheritance occurs when both alleles are fully expressed, such as red and white patches appearing together.
What is codominance?
