genetics 1
what is a cell
the basic form of life
what is a big square split into 4 that shows phenotypes and genotypes.
punnett square
what is microevolution.
the change in the genetic makeup of a population over time, driven by processes like mutation, natural selection, genetic drift, and gene flow.
what is the theory of evolution
posits that populations of organisms change over time through a process called natural selection, where individuals with traits better suited to their environment are more likely to survive and reproduce, passing on those advantageous traits.
What is a paleontologist?
What is meiosis
A cell division sexually reproducing organisms
what is a phenotype
physical trait of an organism
What is Macroevolution
evolutionary changes that occur above the species level.
Coevolution
What are fossils?
Fossils are the preserved remains or traces of ancient organisms that lived millions of years ago. They can be bones, shells, imprints, or even traces like footprints.
what is mitosis
Mitosis is a process where a single cell divides into two identical daughter cells.
what is a genotype
Organisms genes, which determines the characteristics, and traits of it.
What is migration
Migration is the movement of people or animals from one place to another. This can happen for various reasons, such as searching for food, better living conditions, or escaping danger.
what is the theory of evolution
The theory of evolution is a scientific explanation for how species change over time. It was first proposed by Charles Darwin in the 19th century.
How are fossils formed?
Fossils typically form when an organism is buried quickly after death, often in sediment. Over time, minerals replace the organic material, turning it into rock.
what is the difference between animal cells and plants cells.
plant cells have a rigid cell wall, chloroplasts for photosynthesis, and a large central vacuole
what is it called when an organism has two traits
heterozygous
genetic drift
It can occur due to random events, like natural disasters, that drastically reduce the population size. usually occurs with a small population.
who was charles darwin
biologist best known for his theory of evolution by natural selection. Darwin's work was inspired by his observations during a voyage on the HMS Beagle, particularly his studies of the diverse species on the Galápagos Islands.
What can fossils tell us?
Fossils provide clues about the history of life on Earth, including how organisms have evolved over time and what past environments were like.
what does the cytoplasm do?
holding the components of the cell and protects them from damage.
A cat is homozygous recessive light blue, and the other cat is homozygous dominant what is the gene traits
Tt Tt Tt Tt
100% Blue
what is natural selection
This is the process where individuals with traits better suited to their environment tend to survive and reproduce more, passing those traits to the next generation.
who was Gregor mendel
"Father of Genetics." He conducted experiments with pea plants in the mid-1800s to study how traits are inherited from one generation to the next. By observing how traits like flower color and seed shape were passed down
Where are fossils found?
Fossils are usually found in sedimentary rocks, which are formed by the accumulation of sediments. They can also be found in places like tar pits, amber, and ice.
