Key terms
This is term used for passing of traits and characteristics from parents to offsprings
Heredity
This type of reproduction has a downside of not offering variety because there is only one parent
Asexual reproduction
A segment of DNA that codes for traits
Gene
This type of gene is only physically expressed when two of the same gene is inherited
Recessive gene
Different versions or variations of a trait
Allele
This hold the information used to code all traits and is located in every nucleus of every cell in your body. Humans have 23 pairs of these
This type of reproduction has the benefit of genetic variation but has the downside of having to use energy to find a mate
Sexual Reproduction
What type of plant did Mendel use in his genetic experiments?
`Pea plants
This type of gene is expressed even if only one copy is inherited
dominant gene
Two alleles inherited for a particular gene
A chart used to find the possible genotypes in offspring of two parents
Punnett square
An animal or plant resulting from a cross between genetically unlike individuals
Hybrid
In Mendel's experiments what percent of the F1 generation expressed the dominant factor
100%
a genetic condition in which neither allele is dominant or recessive and both will be expressed
Co-dominant gene
Having the same alleles for a particular gene
homozygous
When multiple genes determine the phenotype of a trait
Polygenic inheritance
the genotypic and phenotypic differences between individuals in a population, and between populations. It increases the chances of survival and reduces the chance of inheriting harmful diseases from parents
Genetic variation
Known as the father of Genetics
Gregor Mendel
a genetic condition in which both alleles are expressed and the result is an intermediate trait between the two allele traits
Incomplete dominant gene
Double Jeopardy
Having two different alleles of a particular gene
heterozygous
What letters represent this genotype if one parent had AA and the other had aa?
A form of asexual reproduction where a new organism grows as an outgrowth from the parent and then detaches
Budding
Process in which pollen is transferred to the egg of the same plant or a different plant of the same species so fertilization can occurq
What symbol was used to represent the parental generation in Mendel's experiments?
P
the name for the physical expression of an organism's genotype
Phenotype
Why is genetic variation important (name one reason)
-increases chances of survival in environmental changes (like drought or disease outbreak)
-decreases risk of inherited diseases
