Concept explainers

Genetic Variation

Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.

Quantitative Genetics

Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.

A diploid species has four chromosomes per set for a total of eightchromosomes in its somatic cells. Draw such a cell as it wouldlook in late prophase of meiosis II and prophase of mitosis. Discuss how prophase of meiosis II and prophase of mitosis differfrom each other, and explain how the difference originates.
Somatic cells in organisms of a particular diploidplant species normally have 14 chromosomes. Thechromosomes in the gametes are numbered from 1through 7. Rarely, zygotes are formed that containmore or fewer than 14 chromosomes. For each of thezygotes below, (i) state whether the chromosomecomplement is euploid or aneuploid; (ii) provideterms that describe the individual’s genetic makeupas accurately as possible; and (iii) state whether ornot the individual will likely develop through theembryonic stages to make an adult plant, and if so,whether or not this plant will be fertile.a. 11 22 33 44 5 66 77b. 111 22 33 44 555 66 77c. 111 222 333 444 555 666 777d. 1111 2222 3333 4444 5555 6666 7777

6) The plant Haplepoppus gracilis is diploid (2n = 4). Inside each cell (represented here by the oval) there are four total chromosomes: one long pair (represented by "A" and "a") and one short pair (represented by "B" and “b"). The following diagrams represent possible anaphases of this cell during meiosis or mitosis. The lines represent chromosomes/chromatids being pulled to either the north or south pole of the cell, and the vertex of each "V" represent the centromere which would be attached to kinetochore microtubules. For representative cells 1– 12, say if the diagram represents a cell in anaphase I of meiosis I, anaphase II of meiosis II, anaphase of mitosis, or shows an impossible situation. If the situation is impossible, explain why. い。 VA Vb VA VB VV. V b Va VB VAVA Vo VB ^^ ^ が VaVA Vo VB くs

A male Drosophila from a wild-type stock is discovered to haveonly seven chromosomes, whereas normally 2n = 8. Closeexamination reveals that one member of chromosome IV (thesmallest chromosome) is attached to (translocated to) the distalend of chromosome II and is missing its centromere, thusaccounting for the reduction in chromosome number. (a) Diagram all members of chromosomes II and IV duringsynapsis in meiosis I.
