BIO212/GS 6 Chromosomal Abnormalities • Somatic chromosomes ( 1 to 22 in humans) or Sex Chromosomes (X,Y) • Numerical Abnormalities • Aneuploidy: variations in chromosome number that do not involve the whole sets of chromosomes, but only parts of a set. • Polyploidy: having extra sets of chromosomes.
See Page 1. B CA) They are the reason one gene can affect more than one character. B) They allow for a range of traits in the population.C) They are the reason the environment can affect characters. D) They make it possible for one person to have more than two alleles for a gene.11) What is the significance of multiple alleles?
Chromosome deletion-loss of part of chromosome during meiosis Congenital- present at birth Cystic fibrosis-autosomal recessive disease caused by a defective sodium ion transporter gene Double Y syndrome-is the presence of an extra Y chromosome in males Down syndrome-is a condition resulting in trisomy of chromosome 21 Fetal alcohol syndrome-is the development …
Women get two X chromosomes, one from their mother (XX) and one from their father (XY). They’re more likely to inherit the necessary gene mutation from both X chromosomes. Men only get one X chromosome. Their mutations usually result in anomalous trichromacy or color blindness.
This results in your ability to perceive those colors. Tetrachromats have a fourth type of cone featuring a photopigment that allows perception of more colors that aren’t on the typically visible spectrum. The spectrum is better known as ROY G. BIV ( R ed, O range, Y ellow, G reen, B lue, I ndigo, and V iolet).
The typical human has three types of cones near the retina that allow you to see various colors on the spectrum: 1 short-wave (S) cones: sensitive to colors with short wavelengths, such as purple and blue 2 middle-wave (M) cones: sensitive to colors with medium wavelengths, such as yellow and green 3 long-wave (L) cones: sensitive to colors with long wavelengths, such as red and orange
They’re located inside the retina. That’s a layer of thin tissue at the back of your eyeball near your optic nerve. Rods and cones are crucial to sight. Rods are sensitive to light and are important for allowing you to see in the dark. Cones are responsible for allowing you to see colors.

Men are actually more likely to be color blind or unable to perceive as many colors as women. This is due to inherited abnormalities in their cones. Let’s learn more about how tetrachromacy stacks up against typical trichromatic vision, what causes tetrachromacy, and how you can find out if you have it.
X-linked disorders. Duchenne muscular dystrophy, hemophilia, and fragile X syndrome are all X-linked disorders whose genes are found on the X chromosome. Because males only have one X chromosome, they exhibit the disease significantly more frequently than females.
There is a misconception that girls cannot inherit recessive X-linked disorders. Girls can in fact inherit these disorders, but at a lower rate than boys. The following choices give the genotypes for pairs of mothers and fathers. Which pair of parents could have a daughter with the recessive disorder a?

Marfan syndrome occurs when an individual inherits one or two copies of the defective FBN1 gene. Marfan syndrome is caused by a defect in FBN1 gene located on chromosome 15. The gene normally encodes the fibrilllin-1, which is important for the elasticity and appropriate growth of connective tissue.
