Answer: Resources are always limited.

Exponential growth can be defined as the increase in the number of members in a population, at a constantly growing rate. In nature population may grow exponentially for some period but ultimately decline due to limitation in resource availability. Resources are available to population according to the carrying capacity of the region or ecosystem. Carrying capacity can be defined as the maximum number of individuals that an ecosystem can sustain on the basis of availability of resources like food, shelter and others.

The natural populations cannot keep growing exponentially because the increase in the size of the population may exceed the carrying capacity of the region or ecosystem. This has resulted due to the limitation of resources.

Iteru [2.4K]

Answer:

Rr and rr

Explanation:

The genotypes of the parents would be heterozygous red (Rr) and true-breeding white (rr).

<em>Since the allele for the red flower color (R) is dominant over that of the white flower color (r), for a cross to produce both red and white flower color plants, the red parent must be heterozygous (Rr) and the white parent true-breeding (rr). </em>

Rr x rr

Rr Rr rr rr

Rr = red

rr = white

If the red parents is true-breeding

RR x rr

Rr Rr Rr Rr

All their offspring would be red without any white flower color.

Hence, the genotypes of the parent are Rr and rr.
