Biology Flashcards

Asexual reproduction

process of reproduction involving a single parent

Binary Fission

type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identical daughter cells.



Chromosome Number





Process of copying DNA prior to cell division

Dominant traits


Recessive traits



Having two different alleles for a particular gene


Having two identical alleles for a particular gene.


One of a number of different forms of a gene


Process in sexual reproduction in which male and female reproductive cells join to form a new cell.


Fertilized egg


Sequence of DNA that codes for a protein and thus determines a trait; factor that is passed from parent to offspring.


Part of eukaryotic cell division during which the cell nucleus divides.


Process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.


Sex cell

Crossing over

Process in which homologous chromosomes exchange portions of their chromatids during meiosis.


Chart that shows the presence or absence of a trait according to the relationships within a family across several generations.


Physical characteristics of an organism


Genetic makeup of an organism

Protein synthesis


Punnet Square

Diagram that can be used to predict the genotype and phenotype combinations of a genetic cross.

Genetic cross





Cell organelle consisting of RNA and protein found throughout the cytoplasm in a cell; the site of protein synthesis.

Sex-linked Traits


Sexual reproduction

Type of reproduction in which cells from two parents unite to form the first cell of a new organism.
