Answer:
The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
Explanation:
A mutation is any change, whether big or small, that occurs to the nucleotide sequence of a gene in a cell as caused by mistake during replication or induced by a mutation causing substance. These mutation-causing substances are called MUTAGEN.
A MUTAGEN is any substance that causes genetic mutation in an organism's cell. These changes in the nucleotide sequence can affect one or more phenotypic characteristics of the affected organism, which is also passed to offsprings because it is a genetic change.
Hence, a plant cell exposed to this mutagen will be induced to mutate.
Hence, the cells changing after being exposed to the chemical, which is also passed to the next generation of cells best provides explanation that the chemical is a MUTAGEN.

Asexual: Offspring arise from single organism
Sexual: Genetic information from two organisms (male and female), where one produces a motile gamete (male) that travels to fuse with a larger stationary gamete produced by other (female).
Internal Fertilization: Union of an egg cell with a sperm during sexual reproduction inside the body of a parent.
External Fertilization: The sperm cell reunites with the egg cell in the open, rather than inside the body of a parent.
:) I'm sure you can figure it out from the information I stated above
Eukaryotic cells differ from each other due to their structure and function. Though, two eukaryotic cells could differ in the number and types of organelles they contain.
Answer:
<u> The following four traits are -: </u>
- <u>Pedigree 1 -</u> A recessive trait (autosomal recessive) is expressed by pedigree 1.
- <u>Pedigree 2- Recessive inheritance is defined by Pedigree 2. </u>
- <u>Pedigree 3</u> - The inheritance of the dominant trait (autosomal dominant) is illustrated by Pedigree 3.
- <u>Pedigree 4-</u> An X-like dominant trait is expressed by Pedigree 4.
Explanation:
<u>Explaination of each pedigree chart</u>-
- Pedigree 1 demonstrates the <u>recessive trait </u>since their children have been affected by two unaffected individuals. If the characteristics were X-linked, in order to have an affected daughter, I-1 would have to be affected.
In this, both parents are autosomal recessive trait carriers, so the child will be affected by a 1/4 (aa) - <u> Recessive inheritance</u> is defined by <u>Pedigree 2</u>. This is<u> X-related inheritance as autosomal recessive</u> inheritance has already been accounted for in part 1. This inference is confirmed by evidence showing that the father (I-1) is unaffected and that only the sons exhibit the characteristic in generation II, suggesting that the mother must be the carrier. The individual I-2 is a carrier for this X-linked trait. A typical Xa chromosome is attached to the unaffected father (I-1), so the chance of carrier II-5 is 1/2. Probability of an affected son = 1/2 (probability II-5 is a carrier) x 1/2 (probability II -5 contributes (
) x 1/2 (probability of Y from father II-6) = 1/8. An affected daughter's likelihood is 0 because a typical
must be contributed by II-6. - The inheritance of the<u> dominant trait</u> is demonstrated by <u>Pedigree 3 </u>because affected children still have affected parents (remember that all four diseases are rare). The trait must be <u>autosomal dominant</u> because it is passed down to the son by the affected father. There is a 1/2 risk that the heterozygous mother (II-5) would pass on mutant alleles to a child of either sex for an autosomal dominant feature.
- <u>Pedigree 4</u> is an <u>X-linked dominant function</u> characterized by the transmission to all of his daughters from the affected father but none of his son. On the mutant X chromosome, the father (I-1) passes on to all his daughters and none of his sons. As seen by his normal phenotype, II-6 therefore does not bear the mutation. An affected child's likelihood is 0.
In the question the pedigree chart was missing ,hence it is given below.
