(comprehension) Asexual reproduction and sexual reproduction are DIFFERENT in that A) Asexual reproduction involves a single parent, whereas sexual reproduction involves two. B) Asexual reproduction produces offspring that are genetically identical to the parents, whereas sexual reproduction gives rise to genetically distinct offspring. C) Individuals reproducing asexually transmit 100% of their genes to their progeny, whereas individuals reproducing sexually only transmit 50%. D) Asexual reproduction only requires mitosis, whereas sexual reproduction always involves meiosis. e E) all of the above (recall) A plant with purple flowers is allowed to self-pollinate. Generation after generation, it produces same purple flowers. This is an EXAMPLE of 36. A) hybridization. B) multiple alleles. C) incomplete dominance. D) true-breeding. E) the law of segregation. d. 37. (recall) What is the DIFFERENCE between a monohybrid cross and a dihybrid cross? A) A monohybrid cross involves organisms that are studied for a single trait, whereas a dihybrid cross involves organisms that are studied for two traits. B) A monohybrid cross results in a 9:3:3:1 ratio whereas a dihybrid cross gives a 3:1 ratio. C) A monohybrid cross is performed only once, whereas a dihybrid cross is performed twice. D) A monohybrid cross produces a single progeny, whereas a dihybrid cross produces two progeny. E) A monohybrid cross involves a single parent, whereas a dihybrid cross involves two parents.
