C) conditions in which the germ plasm is a mixture of doeninant D) a circumstance that is E) various stages of development of mitochoedria and chloroplasts 33) It is safe to say that a maternal effect is caused boy the genotype, not the phenotype, of the parent producing the egg 34) One explanation for organelle inheritance is that A) mitochondria and chloroplasts lack DNA and are therefore cytoplasmic contributions B) mitochondria and chloroplasts have DNA that is subject to C) organelles such as mitochondria are always wild type mutation for example, are completely dependent on the nuclear genoeme for E) None of the answers listed is correct 35) Heteroplasm 36) Inheritance of the y is variation in genetic content of organelles TRUE OR FALSE green and white patches phenotype in Mirabilis jalapa (four o'clocks) is an example of maternal influence. TRUE OR FALSE 37) In heteroplasmy, adult cells have variable mixture of normal and abnormal organelles TRUE OR FALSE 38) Organisms with both male and female reproductive organs are said to be all of the above except a. Dieceous b. Hermaphroditic c. Bisexual d. monoecious 39) Mitochondrial mutations are passed equally to offspring by both males and females. TRUE OR FALSE 40) The endosymbiotic theory states that mitochondria and chloroplasts arose independently about 2 billion years ago from free-living protobacteria. True or false 41) An example of organelle heredity involves pigmentation in Mirabilis jalapa. TRUE OR FALSE 42) Monosony is a loss of single chromosome in diploid genome. TRUE OR FALSE

Explanation / Answer

Hi Answer:

Note: The explanation is given only on the False answers.

34. One explanation for organelles inheritance is that…Option B Mitochondria and chloroplasts have DNA that is subject to mutation

Explanation: When a cell divides and produce daughter cells at that time organelles also duplicate and move to daughter cells and place themselves at a proper place this process is organelle inheritance. As both of these organelles (Mitochondria and chloroplast) have their own DNA so both DNA can undergo mutations under specific conditions and when the cells having these mutated organelles divide at that time the mutated DNA also inherited to the daughter cells.

35. Heteroplasmy is variation in the genetic content of organelles …True

36. Inheritance of the green and white patches phenotype in Mirabillus jalapa (four O clock) is a complete example of maternal influence…..False

Explanation: Inheritance of the green and white patches phenotype in Mirabillus jalapa (four O clock) is a complete example of incomplete dominance where genes of an allelomorphic pair are not either expressed as dominant nor expressed as recessive but they express themselves partially when present together in the hybrid.

37. In heteroplasmy, an adult cell has a variable mixture of normal and abnormal organelles…Ture

38. Organisms with both male and female reproductive organs are said to be all of the above except diecious

Explanation: Diecious means that both male and female reproductive organs found on separate individuals of the same species. Whereas, the Hermaphrodite, Bisexual and monoecious have same meaning that both male and female reproductive organs found on the same individual.

39. Mitochondrial mutations are passed equally to offspring by both males and females….False

Explanation: Mitochondrial mutations are passed equally to offspring by the mother or females only.

40. The endosymbiotic theory states that mitochondria and chloroplasts arose independently about 2 billion years ago from free-living protobacteria. …True

41. An example of organelle heredity involves pigmentation in Mirabilis jalapa…True

42. Monosomy is a loss of single chromosome in diploid genome…..True
