Genetic question. Help me out i have an exam on monday.?
Question by maze: Genetic question. Help me out i have an exam on monday.?
In a certain Norwegian families there is an inherited condition known as woolly hair. Those showing this character have hair which resembles sheep’s wool. A study of family pedigrees shows that a person never has woolly hair unless at least one parent also has woolly hair. How would this character most likely be inherited? Explain!
Best answer:
Answer by soccerguy12840
The other parent must have the recessive gene that causes the condition. If one parent was homozygous dominant, it would be impossible for the child to inherit the wooly hair.

Caninie Genetics and Health Testing: What do I need to know?
You don’t need a degree in genetics, or even a college course,
to understand the basics of health testing in dogs.
Every aspect of any dog’s physical being began as contributions
from it’s parent’s bodies,carried in their genetic code. As an
example, there are certain health conditions in Golden
Retrivers, Poodles and Labradors which can be passed from parent
to puppy in the genetic material. Hence are found in the hybrids
known as Goldendoodles (Golden Retriever/Poodle crosses) and
Labradoodles (Labrador Retriver/Poodle crosses). These are
called heritable (that is, “able to be inherited”) disorders. In
only one case, Von Willebrand’s Disease, do we actually know
what gene is responsible. In the case of this disease, a
laboratory can examine cells from a dog to see if the gene is
present. A dog having the gene would not be bred.
In all other instances we cannot look for a gene to tell us of
the presence of a certain disease. We have to look for evidence
of the disease itself. In the case of heritable eye diseases in
Poodles and Doodles, for example, an exam is conducted by a
veterinary opthamologist every year to determine if a disease is
developing. Dogs that show symptoms of a heritable eye disease
are eliminated from the breeding program. Other examples of
heritable diseases tested for by some Doodle breeders include
thyroid disease, some forms of heart disease, Addison’s disease,
sebaceous adenitis, hip dysplasia and diabetes.
The heritable disease found in Doodles that most people seem
familiar with is Hip Dysplasia (HD). This disease is a sort of
Degenerative Joint Disease (DJD) , with symptoms similar to
arthritis in humans. In dogs though, the heritable form of the
disease is not a disease of old age, but can develop while the
dog is still quite young and is obvious on X-rays as the hip
joint has abnormal features which are present from birth. As
with most things, the hip architecture can range from great to
horrible, with some hips in between. Two schemes are commonly
available in the US for evaluating hips. OFA screening relies on
veterinarians reading an x-ray and assigning a rank:
‘Excellent’, ‘Good’, ‘Fair’ ‘Borderline’ or ‘Dysplastic’.
Breeders who base decisions about breeding on OFA generally
agree that ‘Excellent’ and ‘Good’ rankings are fine to breed,
and also agree that ‘Borderline’ or ‘Dysplastic ‘ are not
acceptable for breeding. As with all other decisions where there
are gray areas, some breeders will breed a dog with a ‘Fair’
rank, and others will not. But this is really a judgement call
and not all breeders agree. There is a registry (www.offa.org)
that collects and reports hip assessments to assist in recording
and tracking these rankings. OFA will not certify a dogs hips
until the age of 2 years, however, so some breeders are using a
specialized x-ray technique called PennHIP testing, which can be
done as young as 4 months of age. This test results in a score
for each hip, ranging from .1 to .9, and reflects how tight the
hip joint is, and the average score varies by dog breed. Tighter
hips, that is lower scores, are less likely to develop DJD and
are desirable in any breeding dog. In my opinion, any score
under .3 is clearly breedable. Anything over .6 is clearly not
breedable. In between .3 and .6 is a gray area. Breeders who
utilize this method track the average scores for their breed,
and try to breed only dogs with average or better-than-average
scores. For example, the average hip score for Standard Poodles
is currently .5. If a Poodle were to score .42, in the middle
zone, it would be considered breedable by most because it is
better than average. However .42 would NOT be considered
breedable by most Borzoi breeders because that breed average is
..19!
Mini-Labradoodles are at risk for slightly different problems as
they are bred from Miniature Poodles instead of Standard
Poodles.
What was the real purpose for the “Protection of Genetic Health of the German People?”?
Question by Hallie: What was the real purpose for the “Protection of Genetic Health of the German People?”?
I am writing a report and my teacher wants to know what the purpose of the exam. This was what I wrote….
The Law for the “Protection of Genetic Health of the German People” soon took place. It required all people wanting to marry to submit to a medical assessment, after which a “Certificate of Fitness to Marry” would be issued if they were free of diseases. The certificate was required for a marriage license.
I’m writing a report on the Nuremberg Laws
My teacher believes in more details. But when the reason is really obvious how can you write more details?
The years were during the holocaust of course. Before 1938. What other years do you think the Nuremburg laws came into play??
Best answer:
Answer by rostov
In retrospect the purpose was pretty obvious.
i guess you’d have to reAD SOME books but look at what the laws were and the final outcome.
Lots of information is availbale on the holocaust. Check out some jewish www sites like b’nith Brita.
