In horses, black color (B) is dominant over chestnut color (b). Find the genotype and phenotype ratios of a cross between a hybr
valentina_108 [34]

Answer:

Phenotype: 2:2 or 1:1 / Genotype: 2:2 or 1:1 / 50% probability for chestnut color

Explanation:

If we put the two horses' genotypes in a Punnett square:

         <u> B          b</u>

<u>b</u>        Bb        bb

<u>b</u>        Bb        bb

The phenotype is describing the ending color of the offspring, where 2 of the 4 will be brown (Bb) and 2 of the 4 will be chestnut (bb), resulting in a 2:2 ratio. Genotype only refers to the alleles, where 2 of the 4 will be hybrid (Bb) and 2 of the 4 will be homozygous recessive (bb), again resulting in a 2:2 ratio. There is only a 50% chance that the offspring's phenotype will be chestnut color (bb) because the chestnut allele is recessive.

Outline what has to occur in the body for a reflex and a voluntary action to occur.
enot [183]

Answer:

For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,

movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.

Picture 1 depicts convergent boundary.

Picture 2 depicts divergent boundary.

Picture 3 depicts transform boundary.

<h3>What is a Divergent boundary?</h3>

This occurs when two tectonic plates move away from each other while convergent boundary occurs when the plates collide with each other.

Transform boundary is a fault along a plate boundary where the motion is mostly horizontal.
