The process in which a cell duplicates its Coordination of secondary circular reactions – This chromosomes and then divides into two stage involves more complex combinations of genetically identical daughter cells. Mitosis is the actions, not simple repetitive movements. process by which a cell divides, producing two genetically identical daughter cells with the same 123. B. Biomechanics.

Tertiary circular diminishes as a person ages. reactions involve experimentation with different actions to see varying results, such as making the 138. C. The process by which a germ cell divides, block spin or fall in different ways. producing gametes (sperm or ova) that each contain half of the parent cell’s original 125. C. Traits. Traits are typically inherited complement of chromosomes.Meiosis is the characteristics influenced by nature (genetics), not nurture. process by which germ cells divide to form gametes, 146. D. Both statements are false. The Y each with half the number of chromosomes. chromosome is shorter, not longer, and normal females have two X chromosomes. 139. C. Germ cell. Germ cells are specialized cells that undergo meiosis to produce gametes, which 147. B. Through the simple dominant-recessive carry genetic information to offspring. gene. Recessive genes can remain hidden for generations, explaining how traits like eye shape could Germline cells are the cells that lead to the emerge even if they weren't visible in recent production of gametes, but they do not pass on genes generations. themselves. 148. A. Homozygous. Homozygous refers to having While gametes pass on genes, the term "germ cell" is two identical alleles for a specific gene. more appropriate in this case. Heterozygous means having two different alleles for a 140. A. Germline cells. Germline cells carry genetic specific gene. information that is passed on to the next generation. Monozygotic refers to identical twins, not to allele Germ cells contribute to the production of gametes, pairs. Dizygotic refers to fraternal twins. but "germline cells" is the more accurate term for the lineage of cells that passes on genetic information. 149. B. Recessive allele. A recessive allele is less powerful and only expressed phenotypically when While gametes do carry genetic information, the paired with another recessive allele. process begins with germline cells. A dominant allele is the more powerful gene that 141. D. Both statements are false. The correct terms masks the expression of a recessive gene. are reversed: "embryo" refers to the early stage (up to the eighth week), and "fetus" refers to the later stage 150. C. Carrier. A carrier is an individual who has one (from the ninth week to birth). dominant and one recessive allele, where the recessive allele is not expressed but can be passed to 142. B. It produces 23 chromosomes.Meiosis offspring. produces gametes (sperm and ova) with 23 chromosomes, which is half the typical number of 46 chromosomes in human cells. Mitosis and meiosis are different processes. Meiosis results in gametes with half the number of chromosomes, not a product of mitosis. 143. D. None of the above. Crossing over happens during meiosis, not mitosis, so none of the options are correct for the process during mitosis. Crossing over occurs during meiosis, not mitosis. Independent assortment refers to how chromosomes are distributed into gametes during meiosis, not specifically the exchange of genetic material. Spermatogenesis is the process of sperm cell production and does not describe the exchange of genetic material. 144. A. First statement is true, the second is false. The first statement accurately describes monozygotic twins, while the second statement mistakenly suggests only one egg is released, but in reality, dizygotic twins occur from two separate ova. 145. C. Both statements are true. Humans have 22 pairs of autosomes, which are identical in males and females, and 1 pair of sex chromosomes that differ between males and females.
