<span>Rocks can best be identified by their mineral content. This is because rocks are composed of one or multiple numbers of minerals. Quartz, calcite, feldspars, and micas are examples of minerals that make rock formations possible.

Rocks are the basic component of the Earth's crust. Mountains, hills, and volcanoes are examples of rock formations that occur through time on Earth. One can find rocks all over the Earth and most are usually under the soil. Rocks can be further classified as igneous, sedimentary, or metamorphic rocks.</span>

Why it is important to place the gel in the correct direction in the gel cassette while running it?

k0ka [10]

The gel should be placed in the correct direction so that the DNA bands can move.

DNA is negatively charged due to the presence of phosphate groups, so it can only move towards the positively charged anode, otherwise, it will not move.
So, when gel electrophoresis is done the side of the gel where the wells have been created and DNA samples have been loaded is placed at the side of the cathode, whereas the other side is connected to the anode.
When the current flows, the DNA fragments also move from negatively charged cathode to positively charged anode as per their mass and size.

In a species of chickens, incomplete dominance between alleles for black (B) and white(w) feathers

MariettaO [177]

Answer:

1/2

Explanation:

This question involves a single gene coding for feather color in chickens. The black allele (B) is incompletely dominant over the white allele (W). This means that the allele B will not mask the phenotypic expression of allele W, hence, a third intermediate blue phenotype (BW) will be produced.

According to the question, if two blue chickens are crossed i.e. BW × BW, the gametes B and W will be produced by each parent. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:

BB, BW and WW in the ratio 1:2:1

BB is black, BW is blue, WW is white. Hence, the probability of producing a blue chicken from this cross is 1/2.
