7. Today you examined species diversity in one relatively simple environment. Suppose you were estimating the number of beetles
larisa86 [58]

Answer:

<em>The more the diversity in a location, the more is the diversity in organisms. </em>

<em></em>

Explanation:

Every area has a specific environment which is favorable for the survival of particular species adapted to live in that environment.

If there is such diversity in North California's environment, we will find that the population of beetles will be abundant in areas which are favorable for the survival of the beetle population. It may happen that with the passage of time, the beetle population might evolve and adapt to live in other areas too. Changes in habitat makes species diversity favorable.

In Andalusian fowl, B is the gene for black plumage (head feathers) and B' (pronounced "B prime") is the gene for white plumage.
svet-max [94.6K]

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>
