certain physical features of Turner syndrome, which may
include
short stature ,
"webbing" of the skin of the neck (extra folds of skin
extending from the tops of the shoulders to the sides of
the neck),
a low hairline at the back of the head ,
low-set ears ,
abnormal eye features, including drooping of the eyelids
abnormal bone development, especially the bones of the
hands and elbows ,
a lack of breast development at the expected age (usually
by age 13) ,
an absence of menstruation (amenorrhea) ,
a larger than usual number of moles on the skin ,
People who have Turner syndrome may vary widely in their
characteristics or symptoms of the disorder. Some may have
many features or symptoms, whereas others may experience
only a few.
A special blood test that looks at a person's chromosomes -
called a karyotype - is used to diagnose Turner syndrome.
Several physical characteristics may be noted at birth,
which can alert your child's doctor to the possibility of
TS and cause him or her to order a karyotype. A karyotype
test that indicates Turner syndrome reveals 45 chromosomes
(only one X chromosome), instead of the normal 44 autosomes
and 2 X chromosomes (XX) typically found in females. In
some girls with TS, two X chromosomes are present, but one
is misshapen or missing a piece.

A number of plant species have a recessive allele for albinism; homozygous albino (white) individuals are unable to synthesize chlorophyll. If a tobacco plant heterozygous for albinism is allowed to self-pollinate and 500 seeds germinate: a)how many offspring will be the same genotype as the parent? b)how many seedlings would you expect to be white?
A base deletion occurs in the regulator gene of the LAC operon. Describe how the operation of the LAC operon might be affected?
What situations might be viewed as ethical uses of human cloning? Are you doubtful, fearful, or hopeful about human cloning?
The village of Oblong has 400 normally-shaped residents. Transferrin is an iron carrier found in blood, and electrophoretic variation of this protein is determined by an autosomal codominant system. The citizens of Oblong were typed for their transferrin complements. The distribution of transferrin phenotypes was: 100 CC, 100 CD, and 200 DD. What is the frequency of the C allele?
how to Create population with sufficient genetic diversity ?
Cystic fibrosis (CF) occurs with a frequency of about 1/2500 Caucasian newborns and is inherited as an autosomal recessive. A woman had an older sister die from complications of this disease. CF is not present among relatives of her husband. Both the woman and her husband have normal phenotypes. What is the chance this couple will have a CF child
What is the importance of genetics?
Is biotechnology more dangerous to other gene transfer technologies breeding?
Flower position, stem length, and seed shape were three traits that were studied by Mendel. Each is controlled by an independently assorting gene. If a plant that is heterozygous for all three traits was allowed to self- fertilize, what proportion of the offspring would be expected to show all three dominant phenotypes?
How is Genetic Engineering currently used?
How the positive and negative DNA markers are used in genetic engineering?
In hogs a gene that produces a white belt around the animal's body is dominant over its allele for a uniform body. Another independent dominant gene produces fusion of the hoof (syndactyly). Suppose a uniformly colored hog homozygous for syndactyly is mated with a normal footed hog homozygous for the belted character. What would be the phenotype of the F1? If the F1's interbreed, what would be the phenotypic ratio of the F2?
What ethical dilemmas should be considered when genetic engineering is put into practice?
Suppose you are heterozygous for a mutant beta-thalassemia allele. If the frequency of beta-thalassemia is 1/1600 persons, what is the probabilty that your prospective spouse is heterozygous for a mutant beta-thalassemia allele?
In sesame, the one-pod condition (P) is dominant to the three-pod condition (p), and normal leaf (L) is dominant over wrinkled leaf (l). The two characters are inherited independently. Determine the genotypes and phenotypes of the two plants which produce the following progeny: 318 one- pod normal, 98 one-pod wrinkled, 323 three-pod normal and 104 three-pod wrinkled.
