What does DNA stand for?
What is deoxyribonucleic acid
100
What is heredity
What is the passing of traits (genes) from parent to offspring
100
What is when a new organism is produced when an egg (female) and sperm (male) come together to form a zygote from fertilization.
What is sexual reproduction
100
What are ONE FORM of a gene
What is an allele
100
What is neither allele is dominant so there is a blending of traits when two different alleles for the same trait occur together.
What is incomplete dominance
200
In eukaryotic cells, DNA is found inside
What is the nucleus
200
How to you obtain your genes
What is heredity
200
What process of cell division produces sex cells
What is meiosis
200
What is an allele/trait that will always be expressed and will “mask” the other?
What is dominant
200
What is it called when both alleles contribute to the phenotype of the organism by showing up simultaneously (at the?same time) in heterozygous individuals
What is Co-Dominance
300
DNA is found on
What is chromosomes
300
Who is the father of genetics
What is Gregor Mendel
300
What is when a new organism is produced from one organism. The new organism will have hereditary material (DNA) identical to the hereditary material of the parent organism.
What is mitosis
300
Generally, dominant alleles are represented with a ______________ letter, and recessive alleles are represented with a __________ letter
What is capital letter and lower case letter
300
Attached earlobes are dominant over free hanging earlobes. Complete the Punnett Square for the following individuals: Mom=BB and Dad=bb What is the percentage chance of the offspring having the free hanging earlobes trait?
What is 0%
400
The scientific name for the shape of DNA is
What is a double helix
400
What is another word for heterozygous
What is hybrid
400
How many cells are prouduced after meiosis?
What is four different, unique cells
400
Explain what hybrid and purebred are, and how they are different.
What is Species with two different alleles or two different forms of the gene would be “hybrid” Represented by two different “letters” and by called “heterozygous”. For instance: Bb “Purebred” species have two alleles of the same trait Represented by two of the same letters. This is called homozygous. For instance: BB or bb.

Black hair is homozygous dominant. Brown hair is heterozygous. Blonde hair is homozygous recessive. (This is an example of incomplete dominance.) A woman with black hair marries a man with blonde hair. What percentage of their offsrings would have brown hair?
What is 100%
500
What is a section of DNA on a chromosome that contains instructions for making specific proteins
What is a gene
500
What are the four nitrogen bases, and how do they always pair up
What is Adenine with Thymine and Cytosine with Guanine
500
Explain how haploid and diploid cells differ in the human body.
What is diploids are Human body cells and have 46 chromosomes, or 23 pairs of chromosomes. Haploids are sex cells that do not have pairs of chromosomes. They only have half the number of chromosomes as body cells. Only have 23 indiviudualchromosomes.
500
Explain how genotype and phenotype are related
What is the genotype is the genetic code that produces all your phenotypes, which are your physical triats.

If brown eyes are dominant over blue eyes, is it possible for two brown eyed parents to have a blue eyed child? Explain.
What is Yes, if they are heterozygous dominant for their brown eyes.
