Consider a cross between a man with an X-linked recessive disorder and a woman that's a carrier for the disorder. Approximately

what percent of their children are predicted to express the disorder?

Biology

Vadim26 [7]3 years ago
6 0

Answer:

50%

Explanation:

Let's assume that the X linked allele "a" gives the disorder. Therefore, the genotype of the affected man would be X^aY while the genotype of the carrier woman would be X^aX. A cross between X^aY man and X^aX woman would produce progeny in following phenotype ratio: 1 affected daughter: 1 affected son: 1 normal but carrier daughter: 1 normal son.

Therefore, there are 50% chances that their children can express the disorder.

Which term refers to the energy an object has due to its position?
puteri [66]

Answer:

Potential Energy.

Explanation:

Potential energy, stored energy that depends on different parts of the system's relative position. When compressed or stretched, spring has more potential energy.

A stainless steel ball has more energy than it had when it fell to the world. It is able to do more work in the raised position.

Potential energy is a system's property and not a single body or particle. The earth-consistent system and raised ball, for instance, have greater potential energy as the two are more distinct.

Compare the physical and chemical properties of a compound to those of the elements of which it is composed
zepelin [54]

Answer:

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water H_2O

2H_2O(l)\rightarrow 2H_2(g+O_2(g)

Physical property is defined as the property of a substance which becomes evident during physical changes. Water is liquid at room temperature whereas hydrogen and oxygen are gases at room temperature.

Chemical property is defined as the property of a substance which becomes evident during chemical changes. Water reacts with metals to form bases, hydrogen reacts with metals to form hydrides and oxygen reacts with metals to form oxides.
