100
This is a picture of chromosome pairs that have been stained and arranged by size.
What is a karyotype?
100
The total DNA in each cell nucleus of an organism.
What is a genome?
100
This trait is expressed and masks other traits.
What is a dominant trait?
100
Breeding to produce plants and animals with desired traits.
What is selective breeding?
100
the observable characteristics of an organism
What is phenotype?
200
This is made of DNA and proteins and protects the chromosome from unwinding
What is a telomere?
200
An organism that has a gene from another organism inserted into its DNA
What is a transgenic organism?
200
A genotype with one dominant allele and one recessive allele
What is heterozygous?
200
Breeding an organism with unknown genotype with an organism that is homozygous recessive.
What is a test cross?
200
DNA fragment that contains DNA from another organism
What is recombinant DNA?
300
This means sister chromatids do not separate properly and result in gametes with an abnormal number of chromosomes.
What is nondisjunction?
300
Technology used to manipulate an organisms DNA
What is genetic engineering?
300
This diagram can show all potential offspring from breeding
What is a Punnett square?
300
Cross a seedless orange (ss) with a orange with seed (Ss), what is the phenotypic ratio of the offspring?
2 with seeds (Ss) and 2 without seeds (ss)
300
phenotypic ratio when crossing (Tt) x (Tt)
What is 3:1?
400
Cells replicate DNA and divides to make two identical daughter cells.
What is mitosis?
400
This process uses electric current to separate DNA fragments by size.
What is gel electrophoresis?
400
Mendel's law stating that alleles are distributed randomly
What is the Law of Independent Assortment?
400
Breeding closely related organisms to keep desired traits, can result in harmful recessive traits
What is inbreeding?
400
circular, double-stranded DNA that is a vector in transformation
What is a plasmid?
500
This is a result of an extra chromosome 21
What is Down syndrome (trisomy 21)?
500
This process produces millions of copies of DNA fragments.
What is Polymerase Chain Reaction (PCR)?
500
Allele pairs separate during meiosis to form gametes
What is The Law of Segregation?
500
crossing two individuals with two desired traits. Offspring have both traits.
What is hybridization?
500
The 4 possible allele combinations for a dog with the genotype BbYy
What are BY, By, bY, by?
