What would happen to the possible variation in gametes if the number if chromosome pairs increased from two to three?

1 answer:

7 0

<span>If each of the pairs of chromosomes was heterozygous (what gives you the highest potential number of different gametes), then the number of possible gametes increases from 4 to 8 for a diploid organism. To figure out how many are possible, raise the number of homologous chromsomes (2 for a diploid organism) to the power of the number of chromosomes. So if you have two different chromosomes (A and B), raise 2 to the 2nd power (or multiply 2 x 2) and you have 4. If you have chromosomes A, B, and C, then you have 2^3, or 2 x 2 x 2 = 8.

To show possible combinations, AaBb gives you AB, Ab, aB, or ab. AaBbCc gives possible gametes of ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc. </span>

Answer:

Membrane bound cell organelles

Explanation:

A prokaryotic cell lacks a membrane defined nucleus and all the membrane-bound organelles. A eukaryotic cell has a membrane-bound nucleus and other membrane-bound organelles such as mitochondria, chloroplasts, endoplasmic reticulum, lysosomes, Golgi apparatus, etc.

To determine if a cell is a prokaryotic or eukaryotic, one can look for the nucleus and the membrane-bound organelles. If the cell has a nucleus and membrane-bound organelles, it is a eukaryotic cell. The absence of these structures makes it a prokaryotic cell.

A pea plant is tall. It has one dominant and one recessive trait. What is the phenotype and genotype?

Fantom [35]

Answer: The genotype of the pea plant is Tt. T is the dorminant allele and t is recessive.

Tall is the phenotype.

Explanation:

Genotype is a genes of an individual which show the phenotype or the traits.

From the above question, the pea plant have genes of T tall and t for dwarf,because T is dorminant , it is expressed over recessive.

The genotype of the pea plant is Tt.

Phenotype is the observable or visible characteristics the organism posses which is as a result of the genotype been expressed.

The phenotype is Tall.

List two ways in which water reaches the ocean

Pachacha [2.7K]

Answer:

Precipitation and runoff

Explanation:

The oceans get water in several different manners, with some of them being through precipitation, and through runoff. Whenever there is precipitation on the ocean waters, the water from it of course ends up in it, thus it accumulates it. Also, when there's precipitation on the land, a runoff appears. The runoff is simply the water from the precipitation that moves on the surface, downhill, and usually ends up in some water body. Part of the runoff ends up in the oceans, and that is the runoff that appears on the slopes that are near the ocean and are sloping toward the ocean waters.
