Genetics
Mitosis
A process where a single cell divides into two identical daughter cells
Genotypes
The genetic makeup of an organism.
Definition of microevolution.
Change within a species or small group of organisms, especially over a short period.
What type of process is cloning?
The process of generating a genetically identical copy of a cell or an organism.
What do you call magma that forces it way through internal rock layers?
Intrusions.
Meiosis
A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
Phenotype examples
Examples of phenotypes include height, wing length, and hair color.
Natural selection examples.
Answers may vary.
What does GMO stand for.
Genetically modified organism.
What do you call magma on the outside of the rock?
Extrusions.
Cells produced(mitosis)
Two identical daughter cells from a single parent cell.
What 2 things does a Punnett square predict?
The percentages of phenotypes in the offspring of a cross from known genotypes.
Migration definition.
Seasonal movement of animals from one region to another.
What is selective breeding?
The process where humans choose which organisms with specific traits will reproduce, aiming to enhance or develop desired characteristics in future generations.
Are older fossils closer to the top or bottom?
Bottom.
Cells produced(meiosis)
Four haploid cells (gametes).
What is homozygous.
An organism is homozygous when two alleles present for a particular trait are identical to each other.
What is a mutation?
A change in the DNA sequence of a cell
What is Artificial Selection?
The process where humans choose which organisms with specific traits will reproduce, aiming to enhance or develop desired characteristics in future generations.
What is a simple definition of fossil?
The preserved remains of plants and animals whose bodies were buried in sediments, such as sand and mud, under ancient seas, lakes and rivers.
What cells do meiosis occur in
Germ cells.
What is a recessive trait?
A trait that must be contributed by both parents in order to appear in the offspring.
Genetic drift definition.
A change in the DNA sequence of a cell
What is Gene Therapy?
An experimental technique that uses genes to treat or prevent disease.
What are some fossil uses?
To date rocks.
