Chloroplasts are unable to survive without the energy they receive from cell respiration. What conclusion can be drawn from this

fact?
It is not possible that chloroplasts ever existed as free-living bacterial cell and endosymbiotic theory is flawed.
As chloroplasts evolved, they transferred genes necessary for surviving on their own to their host cells.
Chloroplasts, unlike mitochondria, evolved from a species of bacteria that relied on anaerobic respiration for energy.
As chloroplasts evolved to convert light energy within a host cell, their own energy requirements increased to an unsustainable level.

In pea plants, smooth (S) peas are dominant over wrinkled (s) peas in the single gene controlling pea texture. A plant with smoo
OlgaM077 [116]

Answer:

Ss and ss

Explanation:

<em>Since the smooth trait (S) is dominant over the wrinkle trait (s), the genotype of the wrinkled pea parent is definitely </em><em>ss</em><em>.</em>

<em>Also, some of the progeny had wrinkled pea texture (ss). Each of the 2 wrinkled alleles must have been donated by each of the parent. It thus means that the smooth pea parent is heterozygous for the trait (</em><em>Ss</em><em>).</em>

Now, let us look at a cross between the two parents;

  Ss   x   ss

Progeny: Ss, Ss, ss, ss.

Phenotypically, 50% of the progeny are smooth peas while 50% are wrinkled.

Looking at the population of each of the phenotype resulting from the cross. 252:247 is approximately a 50:50 ratio.

Hence, the genotypes of the two parents are Ss and ss.
