Genes and Heredity

What is it? Genes are: Nucleotides transferred
from parent to offspring that play a role in determining genotypic and phonotypical outcomes
Heredity is: Acquiring traits from parent to offspring
How are they related? The traits inherited depend on the segregation and recombination of genes.
Importance to the cell Heredity is the process where genes
are passed to the offspring through the parents. This is important because this decides the characteristics of the offspring.
Eye color is an example of an inherited characteristic.
How it works in the cell The DNA sequence of genes carries information
for specific characteristics The different forms of genes (allele) determine
traits. Ex: tall gene is dominant, short gene is recessive
When gametes are produced, two alleles separate and each gamete has one copy of each gene for the offspring.
How it works in the cell An organism with a dominant allele will always
express that trait. An organism with a recessive allele will only
express that trait if there isn’t a dominant allele present.
Single traits such as the shape of your eyes are polygenic- controlled by many genes.
Organelles Involved Mitochondria: Contain own set of genes- involved
in metabolic processes. They are inherited through the maternal line. Chloroplasts: Contain their own DNA Must be inherited by each daughter cell during
cell division Nucleus: Contains genetic material-
chromosomes
