QuestionAnswer
Interphase The time interval between cellular reproduction
Karyotype the figure produced when the chromosomes of a species during metaphase are arranged according to their homologous pairs
Diploid cell a cell with chromosomes that come in homologous pairs
Gametes Haploid cells (n) produced by diploid cells (2n) for the purpose of sexual reproduction
Virus a non-cellular infectious agent that has two characteristics (1) it has genetic material (RNA or DNA) inside a protective protein coat. (2) it cannot reproduce on its own.
What factors besides genetics play a role in determining the characteristics of a person? Environmental factors and Spiritual factors
A cell's DNA consists of 12 pairs of homologous chromosomes. what is its diploid number? what is its haploid number? diploid number is 24. haploid number is 12.
