Diploid biology, genetics definition : 1 noun, a cell or an organism consisting of two sets of chromosomes where one set comes from the mother and another set from the father; 2 adjective, of, or pertaining to, a diploid, that is a cell or an organism with two sets of chromosomes.

Derived term: diploidy. Compare: polyploid , haploid. What is diploid? How many chromosomes are in a human cell? Ploidy refers to the number of sets of homologous chromosomes in the genome of a cell or an organism. Each set is designated by n.

The term diploid refers to a cell or an organism that has two sets of chromosomes. The chromosomes from the two gametes have come together during fertilization. In a diploid state, the haploid number n is doubled, thus, this condition is represented by 2n. An example of a cell in a diploid state is a somatic cell. In humans, the somatic cells typically contain 46 chromosomes in contrast to human haploid gametes egg and sperm cells that have only 23 chromosomes.

How many sets of chromosomes in a diploid cell? Which of these cells is diploid? Egg cell. Sperm cell. Muscle cell. At fertilization, the resulting cell zygote is After meiosis, the four cells are In vascular plants, the sporophyte is Send Your Results Optional. Your Name. To Email. Time is Up! Polyploidy Humans are diploid creatures. Meiosis and Alternation of Generations Plants are characterized by having alternation of generations in their life cycles.

Human Reproduction and Fertilization For human species to obviate extinction, reproductive mature adults should be producing viable offspring in order to continue the existence of the species and pass on genetic information from generation to generation. Developmental Biology Developmental biology is a biological science that is primarily concerned with how a living thing grows and attains maturity.

Bryophytes Bryophytes nonvascular plants are a plant group characterized by lacking vascular tissues. Non-Mendelian Inheritance In this tutorial, find out more about certain types of inheritance that does not follow the Mendelian inheritance patterns. Related Articles A cell that possesses only one set of chromosomes. Cells that possess two sets of chromosomes.

These cells are produced as a result of meiotic cell division. Mitotic cell division results in the formation of diploid cells.

Cells that are diploid contain two copies of each chromosome and therefore two copies of each Gene A segment of DNA that encodes for a particular polypeptide. That is, the DNA sequence that contains the biological instructions for the production of a polypeptide chain, usually a specific protein or component of a protein. The exception to this are males who have one X and one Y chromosome.

This mixing of genomic material ensures that offspring are genetically different from their parents. Cells can sometimes contain more or less copies of the chromosomes which can cause conditions or diseases see aneuploidy.

What happens when either of these processes goes awry? Aa Aa Aa. Gene Transmission in Mitosis. Figure 1. Gene Transmission in Meiosis. Figure 2: Examples of polytene chromosomes. Pairing of homologous chromatids results in hundreds to thousands of individual chromatid copies aligned tightly in parallel to produce giant, "polytene" chromosomes.

High-pressure treatment of polytene chromosomes improves structural resolution. Nature Methods 4, All rights reserved. Aberrations That Alter Chromosome Number. Figure 3: Nondisjunction results in daughter cells with unusual chromosome numbers. Nondisjunction, in which chromosomes fail to separate equally, can occur in meiosis I first row , meiosis II second row , and mitosis third row.

These unequal separations can produce daughter cells with unexpected chromosome numbers, called aneuploids. When a haploid gamete does not receive a chromosome during meiosis as a result of nondisjunction, it combines with another gamete to form a monosomic zygote. When a gamete receives a complete homologous chromosome pair as a result of nondisjunction, it combines with another gamete to form a trisomic zygote. Genetics: A Conceptual Approach , 2nd ed.
