Answer:
A. DNA replication
B. Two haploid daughter cells
C. Four haploid daughter cells
D. No, they are not the same
E. Gametes
Explanation:
A) Step 1 and Step 2, according to the image attached to this question, depicts the stages of interphase where the REPLICATION of genetic material occurs i.e formation of sister chromatids.
B) Meiosis occurs in two division steps namely meiosis I and meiosis II. Meiosis I, which involves the separation of homologous chromosomes produces TWO haploid daughter cells.
C). However, in meiosis II, sister chromatids separate to produce FOUR haploid daughter cells.
D) The cells in step 4 are not all the same due to a process called CROSSING OVER, which occurs in the Prophase of meiosis I. Crossing over exchanges chromosomal segments between two non-sister chromatids of homologous chromosomes as seen in the color of the images attached.
E) The four daughter cells produced in step 4 will mature into GAMETES, which will be used in sexual reproduction.
Answer:
These kinds of mutations are referred to as Lethal mutations
Explanation:
This type of mutation deleteriously affects the vital genes that are responsible for the core functions of the body. The heart supplies blood to the body organs for nutrients and oxygen while kidneys filter out toxins and end products of metabolism. Mutations in genes for development of these organs will be deadly.
