Create a punnett square to solve the following sex-linked inheritance problem (remember to use the sand
ss a male who does not have hemophilia with a woman who does hoy
hemophilia is a sex-linked recessive trait. cross a male who does not have hemophilia with
hemophilia. what is the probability of the following:
male children with hemophilia:
male children without hemophilia:
female children with hemophilia:
female children that are carriers for hemophilia:

Answer AND Explanation:

Let H represent gene for normal blood clotting and h for haemophilia.

              XH               Y

Xh          XHXh           XhY

Xh          XhXH           XhY

Male children with hemophilia:  50%

Male children without hemophilia: 0 %

Female children with hemophilia:  0%

Female children that are carriers for hemophilia: 50%

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
