What is genetics?
The study of heredity.
What is heredity?
The passage of genetic instructions (traits) from parent to offspring.
Some genes can be hidden or covered up by another. These are considered to be- (are present in genotypes but not displayed in the phenotype)
Recessive
Replicate this DNA strand:
GGT-ACG-CGT-AAT
CCA-TGC-GCA-TTA
Where are genes located?
In the DNA or Chromosome
Who first studied heredity and the passage of traits from one generation to the next?
Gregor Mendel
The Expression of a trait. (Physical Trait)
Phenotype
What is the punnet square used for?
To determine the possibility of offspring's genetic makeup.
What are characteristics?
Examples: hair color, eye color, height, skin color, etc... What is a feature that has different forms in a population?
Certain parts of DNA that code for a trait.
Genes
For some traits, only one copy of a particular gene is needed to show a given trait. These genes are referred to as________ and are stronger.
Dominate Traits
What do capital and lowercase letters represent in genotypes? Example: Aa, BB, Dd, CC, Ll
Capital = Dominant Trait Lower Case = Recessive Trait
Define: allele
pairs or series of genes on a chromosome that determine the hereditary characteristics. An example of an allele is the gene that determines hair color.
The physical trait observed in an offspring is known as it's -
Phenotype
The trait that is most likely to disappear in the first generation?
What are recessive traits?
What would be the Amino Acid Chain for this set of DNA instructions.
ACC-TTA-GAG-ACT
RNA:UGG-AAU-CUC-UGA
Amino Chain: Tryptophan-Asparagine-Leucine-Stop
What do we call the genetic make up of the individual, represented by a set of letters?
Genotype
What is the trait that would be present in this Genotype?
aa
Recessive Trait
The process when the Ribosome reads RNA nucleotides, grabs amino acids, and builds proteins
Translation
Long ears are dominant (E) in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygours reccessive (e), what is the only possible genotype of the offspring?
Ee
Dark brown is dominant and white fur is recessive. Both parents are heterozygous. What will be the percentage of dark fur and the percentage of white fur for the offspring?
Two dark brown rabbits have four offspring. Three of the offspring are dark (75%) and one is white (25%).
