Genes
Different versions of the same gene (or trait) are called what?
Alleles
What does DNA stand for?
Deoxyribonucleic Acid
How many parent(s) are required for asexual reproduction?
1 parent
How many daughter cells does mitosis produce?
2 daughter cells
The type of science studies how traits get passed from parents to offspring
Heredity
A section of DNA that codes for a particular trait is called what?
A gene
How many chromosomes do human cells contain?
46 chromosomes
How many parent(s) are required for sexual reproduction?
2 parents
How many daughter cells does meiosis produce?
4 daughter cells
A allele/trait that dominates or covers up other traits/alleles
A dominant allele
When DNA is in a nucleus, it is found in tightly coiled structures called what?
Chromosomes
What is the structure of DNA called?
A double helix
Which type of reproduction produces offspring that are identical to the parent?
Asexual reproduction
This form of cell division produces diploid cells
Mitosis
A organisms genetic makeup for a trait, or their combination of alleles (ex: AA, Aa or aa)
When a organisms has 2 different alleles for a trait it is called what? (Ex: Aa)
Heterozygous
What makes up the backbone of a DNA molecule?
Sugar and phosphate
What type of reproduction produces offspring that are not identical to the parent?
Sexual reproduction
This form of cell division produces haploid cells
Meiosis
A organisms physical feature for a particular trait (ex: red hair, blue eyes)
Phenotype
When a organisms has two of the same alleles for a particular trait it is called what? (Ex: AA or aa)
Homozygous
What are the 4 nucleotide bases that make up DNA?
Adenine, Guanine, Cytosine and Thymine
Mitosis is a example of what type of reproduction?
Asexual reproduction
What are the 4 main phases of mitosis?
Prophase, metaphase, anaphase and telophase
This is the process where humans choose to mate 2 particular animals in hopes that their offspring will possess the same desired traits
Selective Breeding
