no it is not true that plant and animal cells are exactly alike.
in sexual reproduction,an offspring gets 23 pairs of chromosomes from both parent- as in meiosis cell division.therefore this lead to a differences in the genetic material through which humans were made.NOTE-DURING MEIOSIS CELL DIVISION THE CELL MAKES SURE THE PAIRS OF CHROMOSOMES FROM BOTH PARENT ARE DIFFERENT,THAT LEADS TO VARIATION WITHIN OFFSPRINGS AND PARENTS.CERTAINLY YOU DO NOT LOOK EXACTLY LIKE EITHER PARENT.FACIAL APPERANCE COULD BE THE SAME BUT NOT BEHAVIOURAL PATTERN.IT IS SHARED.
A new strand of DNA exactly alike to the original is created.
They are all 1N (haploid) and they all come from the same individual (assuming the question is regarding the gametes produced by a single individual).
Mitosis is the process in where cells are made throughout the body. The process is called IPMAT, this stands for Interphase Prophase Metaphase Anaphase Telophase Mitosis makes different cells with different functions for specific body functions except for the sex gametes. Meiosis on the other hand makes the sex gametes and its process is the same except it is repeated twice. It is called IPMATPMAT Interphase Prohase Metaphase Anaphase Telophase Prophase Metaphase Anaphase Telophase Meiosis can only make sex gametes and nothing more.
they both involve the reproducing of cells
Each sperm and egg cell are genetically different, because during meiosis, recombination by crossing over happens. Chromosomes exchange genetic material between TWO chomatids of homologous chromosomes out of four in a bivalent. Thus 50% gametes are parental and 50% new combinations.
heredity is determined by the passing down of genes from each parent, we have 46 chromosomes, 23 from each parent, this is where you get the genes to cross over during meiosis (the cell cycle of producing gametes) When crossing over occurs, it heightens the random chance of inherited traits. Each parent has their own two chromosomes to split up so this is why no one looks exactly alike or a complete mesh between the two parents. =)

They can look alike but, they don't look exactly alike. No two of any species are exactly the same.
They are very similar but not exactly alike.
