A man is brachydactylous (very short fingers; rare autosomal dominant), and his wife is not. Both can taste the chemical phenylt

hiocarbamide (autosomal dominant; common allele), but their mothers could not. Give the genotypes of the couple. If the genes assort independently and the couple has four children, what is the probability of all of them being brachydactylous

Answer:

The correct answer is -

A) BbTt x bbTt

B) .5^4 or 1/16 or 0.0625

Explanation:

As it is given that Brachydactylus and PTC tasters both traits are autosomal dominant conditions which mean only one allele would be enough.

For Branchydactylus and For tasting :  man and women will be heterogeneous.

Hence,

The Genotype of man = BbTt

The Genotype of wife = bbTt

b. Answer = 0.0625

For Branchydactylus:

Bb X bb

Possible genotypes:

B b

b Bb( Brachydactylus) bb(normal)

b Bb (Brachydactylus) bb (normal)

The probability of a single child being Branchydactylus = 2/4 = 0.5

So,  Probability of all 4 child being Branchydactylus = .5 x .5 x .5 x .5 = 0.0625

The synapse is typically located between the _____ of the first (sending) neuron and the _____ of the second (receiving) neuron.
uysha [10]

Answer:

axon; dendrite

Explanation:

A neuron has three main parts. These are axons, dendrites, and a cell body. Synapse is the site of communication between two neurons. The first neuron of a synapse is called the presynaptic neuron (sending neuron) while the second one is called the postsynaptic neuron (receiving). The axon of the presynaptic neuron and the dendrites of the postsynaptic neuron communicate with each other at the synapse as the axon of the first neuron delivers the nerve impulse away from the cell body.

Dendrites function as the receiving or input portions of a neuron. The plasma membranes of dendrites have numerous receptor sites for binding chemical messengers from the presynaptic neuron.

Vladimir79 [104]
<h2>Answer:</h2>

Geographical location is the single most important factor in determining the temperature of a region.

<h3>Explanation:</h3>

The location of an area and its surrounding environment is most important in its temperature determination. As the area located near to the ocean has a low temperature. And areas which are far away from the waters and there is low precipitation which means low rain. It indicates the higher temperature areas.

Elevation of region, height from the sea level also affects the temperature of region.
