The pattern of inheritance of the offspring of a hemophiliac father would be heterozygous.

<h3>What is Hemophilia?</h3>

Hemophilia is defined as the sex–linked disorder that occurs due to an abnormality of the X chromosome.

A father that has hemophilia would be affected only on his X chromosome and can only pass it to their children making them carries.

This is because the children would inherit only one X chromosome from their father and a healthy X chromosome from their mother.

A postsynaptic neuron has three presynaptic inputs - from neurons X, Y, and Z. Stimulation of neuron X causes the postsynaptic n

xenn [34]

Answer:

Y is probably excitatory and Z is probably inhibitory

Explanation:

Two neurons communicate with each other generally by releasing neurotransmitters.
The neuron which releases the neurotransmitter is termed as presynaptic neuron and the neuron to which the neurotransmitter binds to exert its effects is called as postsynaptic neuron.
Based on the nature of the neurotransmitter released, the presynaptic neurons can either be inhibitory or excitatory in nature.
The change in the membrane potential of the postsynaptic neurons depends on the total sum of inputs coming from different pre synaptic neurons at a given time.
From the given situation, the stimulation by X alone is causing deploarization of 0.5 mV which shows that it is causing excitation, and since depolarization is increasing when X and Y are stimulaneously stimulated Y is also excitatory in nature. However the depolarisation is not occurring when X and Z are stimualted together and hence, Z is probably inhibitory in nature.

Bruce has a genetic disorder. bruce and his wife, kim, have three children, one of which has the genetic disorder. how is this d

laiz [17]

This would be a recessive disease.

Father is dd
Mother is Dd (has to be because one child has the disease)

Parents cross is dd x Dd which gives rise to Dd (0.5) and dd (0.5). Each time they have a child they have a 50% chance of the child having the disease. In their case, only one of their 3 children is dd. The others though are carriers!

Cellular respiration allows organisms to release the energy stored in the chemical bonds of glucose, C6H12O6. The energy in gluc

madam [21]

Aerobic cellular respiration, glucose is metabolised in the presence of oxygen and leads to the formation of energy as a main product. the by products are carbon dioxide and water. The process takes place in four phases: glycolysis, pyruvate oxidation, citric acid cycle, and oxidative phosphorylation.

In garden peas, tall (T) vine is dominant over short (t) vine, and round pea pod (R) is dominant over wrinkled pea pod (r). Cro

Aleksandr [31]

Answer:

Explanation:

Given:

Traits

T (tall, dominant) and t (short)

R (round, dominant) and r (wrinkle)

Crossing parents

hetero-zygous. tall wrinkled (Ttrr)

phenotype tall is given hetero-zygous., so Tt

phenotype wrinkled is recessive, so must be homo-zygous rr

Foiled genotypes (Tr, tr, each with 50%)

short hetero-zygous. round (ttRr)

phenotype short is recessive, so homo-zygous rr

phenotype round is given heteroz. so Rr

Foiled genotypes (tR, tr, each with 50%)
