Skin color in a certain species of fish is inherited by a single gene with four different alleles. How many different types of g
k0ka [10]

Answer:

4

Explanation:

According to Mendel's law of purity of gametes, each gamete contains single allele for a gene. The alleles of a gene segregate during gamete formation and each gamete has one allele for a gene irrespective of the total number of alleles for a gene.  

If the gene for skin color in a fish species has four alleles, an individuals fish would have only two alleles which in turn would segregate during gamete formation.

Since there are four different alleles of the gene (let's assume a,b,c, and d), total possible gametes produced by this organism will be = 4. A gamete can have one of the total 4 alleles making total 4 types of the gametes each with a or b or c or d allele.

Mashutka [201]

The new hypotheses proposed by different scientists are often criticized by the others because these new hypotheses contradict the ideas and hypotheses that already exist. Adapting one's mind to a new hypotheses explaining a past event is often difficult when more clear hypotheses were already given earlier. Thus, the hypotheses suggesting the extinction of the dinosaurs are difficult for the scientific community to accept.

Local and global winds are set in motion by air moving in convection cells. Describe the motion of air in a convection cell. Be
IrinaVladis [17]

Answer:

Due to the earth spherical shape, different latitudes of the planet receive varying solar energy levels from the sun. This is due to the differences in how the sun rays hit the earth surfaces and differences in the length of atmosphere the rays have to travel before they reach the earth's surface.

The equatorial regions get the most energy levels from the sun hence their atmosphere gets heated faster and the hottest. The air mass in this latitude, therefore, gets less fast dense  and begins to rise. The cooler and denser air mass from the poles rushes in, through the  lower atmosphere, to replace the void of the rising air.

When this air mass also gets heated, it too begins to rise. Remember the initial air mass cooled as it rose into the upper atmosphere. This now makes it denser than the air mas below it. As the hotter air mass begins to rise from below it pushes the cooler air mass above laterally. After the lateral movement, the air mass begins to sink slowly as it moves towards the poles because the incoming air mass gets denser than the local air mass.

The lateral movement of the convection current moving to the north is deflected to the north-west due to the Coriolis effect of the earth rotation while the lateral movement of the convection current moving south is deflected to the south-west. These pockets of convection currents are called Hadley cells.
