Choose all the answers that apply.

arlik [135]

Answer:

Option A, B, and C are correct

Explanation:

Incomplete dominance means that the trait represented by two alleles expresses themselves equally thereby hindering dominance of any of the allele completely.

Now,

Let us assume the allele of red petals be represented by "R" and the allele of white petals be represented by "r"

The pink flowers will have genotype "Rr"

Now if two pink flowers are crossed, the following offsprings are produced

Rr X Rr

RR, Rr, Rr, rr

Let us evaluate all the options one by one

a) Ration of pink flower to red flower ( Rr:RR)

There are 2 pink (Rr) flower and 1 Red (RR) , thus the ration of pink flower to red flower is 2:1. Option A is correct

b) one out of four offspring is white in color, therefore the % of white flower is

$\frac{1}{4} * 100\\= 25\\$ %. Option B is correct

c) Two pairs RR and rr are homozygous, thus out of four offsprings two are homozygous. Therefore %of homozygous flowers will be

$\frac{2}{4} * 100\\= 50\\$ %. Option C is correct

d) There are two heterozygous offsprings i.e Rr, therefore the % of heterozygous is $\frac{2}{4} * 100\\= 50\\$ %. Option D is incorrect

e) half of the flowers are hybrid. Therefore option e is incorrect

Therefore, Option A, B, and C are correct

Biodiversity Aa Aa Ecologists are interested in quantifying different kinds of biodiversity. In each of the two studies outlined

sattari [20]

Answer:

Based on the first study it is evident that the ecologists are looking for functional diversity as they are making a note of different functions performed by a distinct kind of species found on different plots.

On the other hand, based on the second study it is evident that the ecologists are studying the species diversity as with the assistance of different wavelengths of light reflected by the vegetation, they are differentiating between the vegetation found in different parts of the continent.

The biodiversity helps humans in different ways, that is, by supporting the society in which they live and by maintaining a healthy biosphere. The biodiversity found around helps in the procedure of dead species decomposition, they offer humans with nutritious food, and also acts as natural sieves and clean the water for consumption. Hence, the correct options are 1, 2, and 3.
