State which cells in the human body are diploid and which are haploid The offspring of the P generation is the _____ generation. The two alleles are segregated or separated during the process of meiosis when cells change from diploid to haploid. The homozygous recessive individual will express the recessive trait. More complex organisms, including humans, produce specialised sex cells (gametes) that carry half of the genetic information, then combine these to form new organisms. In alternation of generations, what is the diploid stage of a plant that follows fertilization called? Polar bodies do not function as sex cells.

Take the densities of steel and aluminum balls to be 7800kg/m3and2700kg/m3,7800 \mathrm{kg} / \mathrm{m}^{3} \text { and } 2700 \mathrm{kg} / \mathrm{m}^{3},7800kg/m3and2700kg/m3, respectively. Many organisms package these cells into gametes, such as egg and sperm. Which one do you think is correct? Because the number of alleles was reduced during meiosis . [This cell contains two copies of each chromosome, one from the male parent and the other from the female parent, making it diploid.]. The result is 4 haploid daughter cells known as gametes or egg and sperm cells (each with 23 chromosomes 1 from each pair in the diploid cell). In humans, body (or somatic) cells are diploid, containing two sets of chromosomes (one from each parent).
