In Andalusian fowl, B is the gene for black plumage (head feathers) and B' (pronounced "B prime") is the gene for white plumage.

INCOMPLETE DOMINANCE INHERITANCE:

<span>5.  In Andalusian fowl, B is the gene for black plumage (head feathers) and B' (pronounced "B prime") is the gene for white plumage.  These genes, however, show incomplete dominance.  The heterozygous (BB') condition results in blue plumage.  List the genotypic and phenotypic ratios expected from the following crosses:  a) black x blue  b) blue x blue  c) blue x white</span>

<span>6. </span><span>In snapdragons, petal color is determined by a single gene locus with two alleles making the "red" allele (R) incompletely dominant to the "white" allele (r).  Heterozygotes have petals, which are neither red nor white, but pink.  a) If a true-breeding red flower is pollinated with pollen from a white flower: What fraction of the seeds (F1 generation) would be expected to produce red-flowered plants?  What fraction of the gametes produced by the F1 plants would be expected to bear the R allele?  b) If two pink flowered plants are crossed, what genotypic and phenotypic ratios are expected among the offspring (F1 generation)?</span>

thousands of years

Explanation:

A delta the size of the Mississippi River will take several thousand of years to form because the process of formation of a delta is geologically controlled.

A delta is a place where  river enters or drains into the sea with many mouth or outlets.

Deltas are depositional terrain full of dis-tributaries.

  • For a delta to form, a terrain must be close to the mouth of an ocean or a larger body of water.
  • The entering stream must be large enough and have large amount of sediment.
  • The river mouth must have been cut to the same level with that of the drainage basin.
  • Most rivers such terrain should be at their lower course where they flow with very low velocity.
  • Wave action should be minimal along such coasts.

These processes takes several thousands of years if not millions.

Tectonic plates are pieces of the ________ that float on the more fluid ________ below. A. mantle; crust B. asthenosphere; litho
Soloha48 [4]

Answer:

The answer is E.) Lithosphere, Asthenosphere.

Explanation:

Tectonic plates belong to the layer called Lithosphere. The tectonic plates float on the Asthenosphere which is below the Lithosphere and more fluid than the crust.

From the Earth's surface to the its center we can say that the inside of the Earth is divided into four layers which, starting from the top , are:

i) the crust

ii) the mantle, (Lithosphere, Asthenosphere , Mesosphere)

iii) the outer core

iv) the inner core.

The tectonic plates are part of the Lithosphere and are constantly moving even though the crust is fairly solid. This is because the inner layers

( Asthenosphere , Mesosphere) are much are fluid and are constantly moving which tends to move the tectonic plates. When the tectonic plates collide they do so with tremendous force which leads to earthquakes and sometimes tsunamis as well resulting in a loss of life and property.
