5. To pass its traits on to the next generations, an organism must _________________.
Thanks!!!
Anyone? :( Please ?

-gives up-
1. alleles
2. mitosis. Meiosis
4. DNA
Alleles
Why is it mitosis though?
1. The different versions of genes in chromosome pairs are called alleles. Alleles are alternative forms of a gene that occupy the same position on a paired chromosome.
To find the answer to this question, you can either refer to your science textbook or search for reliable online sources that explain the basic concepts of genetics and the structure of chromosomes.
2. The process in which body cells are duplicated is called mitosis. Mitosis is a type of cell division that results in two identical daughter cells, each having the same number and type of chromosomes as the parent cell.
The process in which the chromosomes in sex cells are reduced by half is called meiosis. Meiosis is a specialized type of cell division that occurs in the production of gametes (sex cells) and results in the formation of four unique daughter cells, each containing half the number of chromosomes found in the parent cell.
You can find the answer to this question in a biology textbook or search online for resources that explain mitosis and meiosis.
3. The fact that the offspring of a white mouse and a black mouse are all gray indicates incomplete dominance. Incomplete dominance occurs when neither allele is completely dominant over the other, resulting in a blending or intermediate phenotype. In this case, the alleles for white fur color and black fur color blend together to produce gray fur color.
To confirm this answer, you can study the principles of genetics and inheritance patterns or look for specific examples of incomplete dominance in genetic studies of mice.
4. Genes are specific sections of DNA. DNA (deoxyribonucleic acid) is a molecule that carries the genetic instructions for the development, functioning, and reproduction of all known living organisms. Genes are segments of DNA that encode instructions for the production of specific proteins, which play various roles in maintaining and regulating the traits and functions of an organism.
You can find this information in biology textbooks, online biology resources, or genetic research materials.
5. To pass its traits on to the next generation, an organism must reproduce. Reproduction is the biological process in which new individuals of the same species are produced, ensuring the continuation of genetic information and the inheritance of traits. There are different modes of reproduction, including sexual reproduction, which involves the combination of genetic material from two parents, and asexual reproduction, which involves the production of offspring without the involvement of gametes (sex cells).
This answer can be found in biology textbooks or articles that discuss the basics of reproduction and inheritance.
