Every organism in an ecosystem relies on other species for survival: Species diversity. An ecosystem is a b<span>iological community of interacting organisms and their physical environment. The survival of one species therefore depends on the survival of other species.</span><span>

Reduced options for mates can lead to inbreeding: Genetic diversity. Inbreeding occurs when closely related individuals breed, and this can lead to the expression of undesirable traits such as those associated with recessive genes.

Decreased diversity can lead to increased susceptibility to disease: Genetic diversity. This is related to inbreeding. The expression of recessive genes can decrease the overall fitness of a species and increase its susceptibility to disease.

The loss of a producer could result in the loss of consumers: Species diversity. This is related to the concept of an ecosystem. Consumers rely on producers as a food source.

When a population becomes small, diversity is lost: Genetic diversity. This is commonly known as the 'founder effect'.</span>

Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers;

gogolik [260]

Answer:

187.5 or rounded off to 188 white, terminal flowers

Explanation:

Let red=R and white=r where R>r; axial=A and terminal=a where A>a

The parents are true-breeding which means that they are homozygous.

P: RRAA x rraa

F1: RrAa

We then cross two plants from the F1 generation

RrAa x RrAa

To find out the probability we look at the different traits individually

Rr x Rr

yielding 1/4 RR (red), 1/2 Rr (red), 1/4 rr (white)

Aa x Aa

yielding 1/4 AA (axial), 1/2 Aa (axial), 1/4 aa (terminal).

We determine which F2 genotypes would allow for red, terminal flowers.

RRaa and Rraa

Then we use the multiplication rule to determine the probability of these occurring

RRaa: 1/4 x 1/4 = 1/16

Rraa: 1/2 x 1/4 = 1/8

Next we use the addition rule

1/16 + 1/8 = 3/16

To find out the number of these plants within the 1000 F2 plants we multiply the probability with 1000

3/16 x 1000= 187.5 red, terminal flowers
