Organization
Cell organelle that is home to DNA.
What is the nucleus?
The passage of genetic instructions (traits) from parent to offspring.
What is heredity?
Traits passed down genetically from your parents versus Learned or obtained during life
What is Inherited vs Acquired?
Some genes can be hidden or covered up by another.
What is Recessive?
Purpose of genes during reproduction
What is "pass on traits from parent to offspring"?
Location of genes
What is DNA?
Form of a gene represented by a letter
Represented by a capital letter, will be expressed in a hybrid versus Represented by a lower case, needs two copies to be expressed
What is dominant versus recessive?
Used to determine the outcome of genetic crossings in offsprings.
What is a Punnett Square?
Examples: hair color, eye color, height, skin color, freckles, etc...
What are traits?
Threadlike structures of coiled up DNA that carry genes
What are chromosomes?
Term used to describe the next generation of organisms?
What is offspring?
A copy of a dominant and recessive allele (Aa) versus Two copies of the same allele (AA or aa)
What is Heterozygous vs. Homozygous?
Percentage of offspring that will have black feathers. A black chicken (BB) is crossed with a black chicken (BB).
What is 100%?
Purpose of uppercase letters in a Punnett Square
What is "to show the dominant gene with a dominant allele"?
Inherited traits that children get from their parents
What are genes?
The physical trait observed in an offspring is known as it's -
What is phenotype?
The genetic makeup of an individual's traits versus The physical trait expressed in an individual
Percentage of children with NO dimples. Having dimples is dominant (D). Not having dimples is recessive. (d) Both parents are heterozygous for the dominant trait.
What is 25%?
Number of parents in asexual reproduction
What is one?
What is a codon?
Number of pairs of chromosomes in humans
What is 23 pairs?
Trait (Eye color) versus Possible form/Version of trait (Blue or Brown)
What is Gene vs. Allele?
Possible genotype of offspring? Long ears are dominant (E) in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygous recessive (e).
What is Ee?
Two dark brown rabbits have four offspring. The offspring all had a 75% chance of dark brown fur and 25% chance of white fur. What does this tell you about the parents' genes for fur color?
Dark brown is dominant and white fur is recessive. What is "both parents are heterozygous for dark brown fur"?
