- A fox's diploid number of chromosomes is 36. How would the number of chromosomes in the fox's body cells compare to the number of chromosomes in its gametes? Top of Form Its body cells and gametes would both have 18 chromosomes. Its body cells and gametes would both have 36 chromosomes. Its body cells would have 18 chromosomes, and its gametes would have 36 chromosomes. Its body cells would have 36 chromosomes, and its gametes would have 18 chromosomes.Is nondisjunction a good or a bad thing? O A. Good because it ensures that each child has the same number of chromosomes as their parents. O B. Good because it usually results in healthier individuals than can be made without it. OC.

- Which of these are true statements about meiosis? Select all that apply O It results in cells that are genetically identical to the original cell It results in cells that are genetically different from each other and the original cell O It produces cells needed for sexual reproduction O It is the process by which multicellular organisms grow and develop O It produces cells with half as many chromosomes as the original cellHi im having some trouble with this question, if someone could help solve these with an explanation it would be very helpful! In cats, a gene on the X chromosome (X-linked) makes the protein amelogenin, which helps direct the formation of tooth enamel. A mutation in an amelogenin allele changes the amino acid sequence of the protein and can cause a condition called amelogenesis imperfecta, leading to defects in a cat’s tooth enamel. In one type of amelogenesis imperfecta in cats, the allele associated with the condition, a, acts in a recessive manner. Its dominant counterpart, A, results in normal levels of amelogenin. Additionally, the dominant allele H at an autosomal locus that regulates the expression of the protein Sonic Hedgehog is responsible for polydactyly (the presence of extra digits on each foot, “double paws”) and the expression of its recessive counterpart h results in the absence of polydactyly (having the 5 digits per front paw, and 4 digits per hind paw).
