Explanation:
crossing over is a process that happens between human organs chromosome in order to increase general diversity. during crossing over part of one chromosome is exchange with another. the result is a hybrid chromosome with a unique pattern of genetic material. gametes gain the ability to be genetically different from their neighbouring gametes after crossing over occurs. this a loss for genetic diversity which will help cell participate in survival of the fittest and the evolution.
Skin cells are also called epithelial cells
Answer:
Cells divide so living things can grow. When organisms grow, it isn't because cells are getting larger. Organisms grow because cells are dividing to produce more and more cells.
Answer:
The student is wrong, spermatozoa are germinal cells and therefore mitochondrial mutations (likewise genomic nuclear mutations) are inherited by offspring
Explanation:
Although the probabilities of inheriting a mutation from a single sperm cell are low, it since an organism produces millions of sperm cells throughout its life span, the mutations in the germinal cells (i.e., sperms and ovules) are inherited by offspring
