Answer:
Explanation:
The hox gene provides a huge amount of important information about evolution. Hox genes duplication made increased morphological complexity possible triggering the formation of neural crest cells and allowed them to disperse throughout the body, forming a variety of structures. They help lay out the basic body forms of many animals including humans, flies and worms.
Answer: Animal cells divide by a cleavage furrow. Plant cells divide by a cell plate that eventually becomes the cell wall. Cytoplasm and cell membranes are necessary for cytokinesis in both plants and animals.
Explanation:
Answer:
The mutated cell will have 25 chromosomes.
Explanation:
Meiosis is a cell division process in sexual reproduction which involves two successive divisions of a cell having a diploid (2n) number of chromosomes into four daughter cells having a haploid (1n) number of chromosomes.
Meiosis consists of two successive nuclear divisions, meiosis I and meiosis II. Each division consists of these stages: prophase, metaphase, anaphase, and telophase.
Anaphase consists of anaphase I and II. During anaphase II, the centromeres linking the two pairs of chromosomes which are called chromatids separate, and the sister chromatids move toward the opposite poles of the cell and are now called chromosomes.
Therefore in the chimpanzee having 48 chromosomes, after underoing meiosis, each daughter cell will have 24 chromosomes. If there is a case of non-separation of one chromosome, the cell will have 1n + 1 chromosomes i.e. 24 + 1 = 25 chromosomes.
