The cell components that are most involved in determining the hair color of each sibling is gene, chromosomes, and nucleus. The correct option is A.

What are genes and chromosomes?

Genes are small spherical-shaped hereditary material that is present on chromosomes in a bead fashion. They contain the hereditary material of the organism. These are uncountable numbers of genes present in the chromosome.

Chromosomes are x shapes of hereditary material that are preset inside the nucleus. It is made up of DNA, genes, and proteins. Genetic characteristics of the genotype of an organism are unique because of unique genetic material, and this can be transferred to another generation from the first generation.

Therefore, the correct option is A. Gene, chromosomes, and nucleus.

Answer:

A

Explanation:C and D is automatically eliminated because humans don't have vacuoles (plants do) as well as B because humans don't have chloroplast

The alternation of generations inthe life cycle of a plant includes the diploid and haploid multicellularstages. diploid and haploid are copies of the chromosomes. The spores in theplant is unicellular and when they start dividing through mitosis, it producesidentical cells. These identical cells are all haploid. Haploid stages containone set of chromosome from either of the parent. These identical cells create amulticellular system called the gametophytes. A gametophyte is the haploid multicellularstage in the life cycle of a plant. The gametophyte makes the gametes. These gametesare responsible for sexual fertilization. It takes place when a sperm (malegametes) from the male fuses into the egg cell (female gametes) of the female. The formation of both male and female gametes creates a diploidzygote. Diploid stages contain one set of chromosome from eachparent. This is where the sporophyte comes in. A sporophyte is the diploidmulticellular stage in the life cycle of the plant. It now contains the twosets of chromosomes from each parent.
