Genetics
The study of heredity and variation of inherited characteristics.
What is "
Genetics"?
The passage of genetic instructions (traits) from parent to offspring.
What is heredity?
Sexual reproduction produces offspring that are genetically _____________ to the parents.
What is Similar?
Some genes can be hidden or covered up by another. It is usually necessary to have both of this type for the phenotype to appear.
What is a Recessive gene?
By means of sexual reproduction through the sharing of one's genes.
How are traits passed from parent to offspring?
Found in the chromosomes; a self-replicating material that is present in nearly all living organisms.
Where do you find DNA?
This individual first studied heredity and the passage of traits from one generation to the next.
Who was Gregor Mendel?
Asexual reproduction produces offspring that are genetically ____________ to the parent.
What is Identical?
A tool used to determine the outcome of genetic traits and particular probabilities.
What is a punnett square?
Examples: hair color, eye color, widows peak, skin color, freckles, etc...
What are possible traits that can be passed on through the genes of your parents?
Threadlike structures of DNA that carry our genes.
What are Chromosomes?
This type of organism was used by Gregor Mendel to study heredity.
What are pea plants?
If you are studying a population of genetically identical individuals, you can conclude that these individuals use this type of reproduction.
What is Asexually?
An example is a black chicken (BB) when crossed with a homozygous black chicken. This percentage of the offspring will also be black.
What is 100% probability in genetic traits?
Dominant and recessive traits are written in this way to distinguish them on a punnett square.
What are capital LETTERS for dominant and lower case for recessive?
Inherited traits that children get from their parents come from these.
What are Genes?
The physical trait observed in an offspring is known as this.
What is a Phenotype?
For some traits, only one copy of a particular gene is needed to show a given trait. These genes are referred as this.
What is a Dominant trait?
Having dimples is dominant (D). Not having dimples is recessive. (d) Both parents are heterozygous for the dominant trait. This percentage is the probability for not having dimples.
What is 25% probability for a genetic trait?
The different forms of a gene that can be dominant and recessive.
What is an allele?
The genetic makeup of the individual, represented by a set of letters.
What is a Genotype?
The number of chromosomes in humans.
What is 23 pairs or 46?
The sorting of chromosomes during sexual reproduction, determines which of these are passed.
Which traits are passed onto the 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), this is the only possible genotype of their offspring.
What is the genotype (Ee) as the only possible offspring outcome?
The spelling of the word, represented by DNA.
What is the spelling DEOXYRIBONUCLEIC ACID?
