Answer:

EeWw

Explanation:

The allele for the earlobe is depicted as e while that of the hairline is w.

A parent that is homzygous recessive for earlobes (ee) and homzygous dominant for hairline (WW) would have the genotype eeWW.

The other parent that is homzygous dominant for unattached earlobes and homzygous recessive for hairline would have the genotype EEww

eeWW x EEww

During meiosis, each genotype will form gametes.

eeWW: eW, eW, eW, eW

EEww: Ew, Ew, Ew, Ew

These gametes will randomly unite during fertilization to produce offspring. Since the same gametes are formed by each parent:

eW x Ew

offspring

100% EeWw (see the attached image for the Punnet's square)

The genotype of all the children would be EeWw and would phenotypically be with unattached earlobes and dominant hairline.

An individual heterozygous for the A and B alleles has a blood type of AB. What type of inheritancepattern is this?

Inga [223]

I need to come up with 5 Questions about eukaryotic and prokaryotic cells

inna [77]

Answer:

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

In the marine mollusk, Aplysia, serotonin binds to a G-protein-coupled receptor and activates a Gs subunit. The resulting activa

dem82 [27]

The serotonin binds to a G-protein -coupled receptor and activates a G-subunit . This results in activation of PKA and closing of the potassium channels. This will subsequently decrease the influx of potassium ions into the cell, and lead to depolarization of the cell. This changes the membrane potential of the cell.

Aplysia are sea slugs which fall under the category of mollusks. Serotonin is a hormone which is responsible for the transfer of electrical signals from the brain to different parts. In this particular mollusk, serotonin was studied to find that it is an essential neurotransmitter that is responsible for the maintenance of synaptic plasticity in the neurons. Synaptic plasticity is the feature which is essential for the communication of neurons. This is the modification which occurs at the synapses during the transmission of synapses. Without this activity, the transmission of signals would be impossible.
