Reproduction
a process of reproduction involving a single parent that results in offspring that are genetically identical to the parent
What is asexual reproduction?
a threadlike structure found in the nucleus of most living cells, carrying genetic information in the form of genes
What is a chromosome?
having two different alleles for a trait
the gradual change in a species over time
What is evolution?
cell division in which the nucleus divides into two nuclei containing the same number of chromosomes
What is mitosis?
a type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identical daughter cells
What is binary fission?
allele or trait that is masked when a dominant allele or trait is present
What is recessive?
the physical characteristics of an organsim
What is phenotype?
a change in DNA sequence that affects genetic information
What is a mutation?
the product of reproduction
What is offspring?
a type of asexual reproduction in which a new organism grows by mitosis and cell division on the body of the parent
What is budding?
the genetic makeup of an organism
What is genotype?
a chart that shows all the possible combinations of alleles that can result from a genetic cross
Punnett Square
a trait that helps an organism survive and reproduce
What is an adaptation?
cell division that produces reproductive cells in sexually reproducing organisms
What is meiosis?
a process of reproduction that involves two parents that combine their genetic material to produce a new organism that differs from both parents
What is sexual reproduction?
the passing traits from parents to offspring
What is heredity?
different forms of a gene
What is allele?
body parts that share a common function, but not structure
What are analogous structures?
differences among individuals in the composition of their genes or other DNA
What is genetic variation?
What is vegetative propagation?
having two identical alleles for a trait
What is homozygous?
allele or trait that is always expressed
What is dominant?
a process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of the traits
What is natural selection?
breeding organisms with specific traits in order to produce offspring with identical traits
What is artificial selection?
