Answer:

The correct answer is -

a) 1/16

b) 1/64

c) 1/32

Explanation:

According to the law of independent assortment, each allele of a particular gene has equal chances of getting inherited into the gametes.

In a Mendelian cross of Aa x Aa would give;

AA = 1/4,

Aa = 2/4 and

aa = 1/4

The result of the cross between AaBb x AaBb would be 1/16 due to the fact that probability is still the same AA = 1/4, BB = 1/4 therefore, AABB = 1/16 = 1/4× 1/4.

Now based on this crossing the following:

AaBbCCDd x AabbCcDd.

Take each allele as individual

Aa x Aa would give; AA = 1/4, Aa = 2/4 and aa = 1/4

Bb x bb would give; BB = 1/2, bb = 1/2

CC x Cc would give; CC = 1/2, Cc = 1/2

Dd x Dd would give; DD = 1/4, Dd = 2/4 and dd = 1/4

Then the probability of progeny of the following would be:

a) the probability of AaBbCcDd = 2/4 x 1/2 x 1/2 x 2/4 = 1/16

b) the probability of aabbCCdd = 1/4 x 1/2 x 1/2 x 1/4 = 1/64

c) the probability of AabbCcDD = 2/4 x 1/2 x 1/2 x 1/4 = 1/32

Serga [27]

People are often able to live in a coma for several years because parts of the body that are not under conscious control continue to function. This situation best reflects the importance of the

A) central nervous system

B) autonomic nervous system

C) somatic nervous system

D) forebrain

Answer:

B) autonomic nervous system

Explanation:

The autonomic nervous system is a part of the peripheral nervous system. It comes under the motor division of the peripheral nervous system. The function of this division of the nervous system is to deliver the motor information from the central nervous system to the smooth muscle, cardiac muscle, and glands.  The responses produced by these muscles and glands are not controlled by the will or conscious of the individuals.  

Due to the functioning of the autonomic nervous system, the person under the coma could perform the activities such as breathing, pumping of heart to deliver the oxygen to the body cells, etc. and stay live.

Which of the following is an example of an animal that might be culled?
Dmitriy789 [7]

Answer:

D. Sami had low birth weight as a lamb but quickly grew into a large sheep.

Explanation:

The Sami lamb is an example of culled because it has the characteristics of quick growth. Culling is the process of separating organisms from a group of same type of organisms due to presence of desired or undesired characteristics. Sami sheep has a unique characteristic of having less weight at time of birth but having quick growth features that make to gain more weight and become large sheep so this sheep is removed from the population for its good traits.
