A plant grows faster and fuller due to large amounts of fertilizer. If the plant cross-pollinates with another plant later, how

will the use of fertilizer on the parent plant affect the plant’s offspring?. A) All of the offspring will be taller than average because the parent plant’s genes were affected.. B) Some of the offspring will be taller than average because some of the alleles were affected.. C) The height of the offspring will not change because the parent’s genes did not change.. D) The height of some of the offspring will be taller if the other parent plant was also fertilized.

The answer is "C" because nothing that your parents do, unless it directly affects/changes the gametes, will pass down to the offspring. Fertilizer is like food, how much your parents have eaten in their childhoods will have no effect on if you are under or over weight. (Unless their weight was by a genetic cause, that might have been passed on to you.)

At what level does gene variability quantify genetic variation?
sergejj [24]

Answer:

Answer is whole-gene or whole-genome.

Explanation:

Genetic variation explains that, no matter how related or identical some organisms might be, there is a or some characters that make them different from one another. These difference is referred to as variation.

Furthermore, whole-gene means the coding and non-coding regions of the DNA>

There are some activities or occurrences that cause genetic variation, these are gene flow, mutation and sexual reproduction.

Examples of genetic variation are color of the eyes, modification of leaf and blood type among others.

Inheritance patterns cannot always be explained by Mendel's models of inheritance. If a pair of homologous chromosomes fails to
soldier1979 [14.2K]

The question is incomplete as it does not have the options which are:

A) n+1; n+1; n-1; n-1

B) n+1; n-1; n; n

C) n+1; n-1; n-1; n-1

D) n+1; n+1; n; n

Answer:

Option-1

Explanation:

The laws of inheritance were concluded from the result of Mendel's experiment which is based on the fact that gametes are formed. Later research suggested that gametes are formed by the process of meiosis which takes place in two phases and recombination is a characteristic of Meiosis.

If during anaphase I of meiosis I, the alleles fails to separate that is nondisjunction takes place at anaphase I, Then the resulting daughter cells will have unequal distribution of chromosomes.

One daughter cell will receive 1 extra copy of the chromosome while another daughter cell will receive 1 less chromosome therefore ploidy level will be n+1 and n-1.

During meiosis II, 2 more daughter cells will be formed with the same ploidy level therefore in last the meiosis will result in 2 (n+1) and 2 (n-1) cell.

Thus, Option-1 is the correct answer.
