Chapter 14 Case Study: Genetic dwarfism Seven months pregnant, an expectant mother was under-going a routine ultrasound. While p

rior tests had been normal, this one showed that the limbs of the fetus were unusually short. The doctor suspected that the baby might have a genetic form of dwarfism called achondroplasia. He told her that the disorder was due to an autosomal dominant mutation and occurred with a frequency of about 1 in 25,000 births. The expectant mother had studied genetics in college and immediately raised several questions. How would you answer two of them? 1. How could her baby have a dominantly inherited disorder if there was no history of this condition on either side of the family? 2. Is the mutation more likely to have come from the mother or the father?

1.) Achodroplasia is a autosomal dominant disorder, the suspected case suggested that inorder for the parents to produce and offspring with achondroplasia. One parents must have a single mutant gene of achodroplasia to be inherited by his offspring. for this case, It is suggested that the offspring might have developed its own mutant gene as it only affect 1 in 25,000 birth. There is changes of genes during early development.

2.) The mother said that they don't have that history of disorder. again, it's autosomal dominant disorder. one parents must have that kind of disorder so their child can also inherit it. Thus, no of the childs parents is a carrier.

How does making models help scientists observe ...????<br>HELP
olga nikolaevna [1]
Building models doesn't actually help scientists observe phenomena. Scientists build models to describe how nature and systems operate then make observations to see if their models match what they observe. Models which don't match what they observe are either alterated or scrapped. Good models are kept and used by the scientific community.

PLS help me with my biology HW, I forgot what the answer was!
Sunny_sXe [5.5K]

Answer:

Contracted blood vessels

Explanation:

The volume of blood is reduced as the vessels are more narrow due to the contraction, so less blood reaches the respiring tissues, causing the force of blood flow to increase as there is less space for normal blood flow to occur. This means that blood pressure increases.
