A. In cross-fertilization the gametes from one plant are used to fertilize the gametes of another plantB. In cross-fertilization the gametes from one plant are used to fertilize the gametes from the same plant C. In self-fertilization the gametes from one plant are used to fertilize the gametes from another plantD. In cross-fertilization insects are used to pollinate the plants while in self-fertilization the investigator pollinates the plants
- Heritable variation is required for which of the following? A) Evolution B) Asexual reproduction C) Mitosis D) MeiosisIn fruit flies a dominant mutation on the X chromosome causes the eye to be oval instead of round (recessive). If a male with oval eyes has offspring with a female with round eyes, what percentage of the male offspring will have oval eyes? O O O a) 0 b) 25 c) 50 d) 75 e) 100what process is important for creating genetic variability among organisms that reproduce primarily by asexual means?
- 2) Meiosis and sexual reproduction are, in large part, responsible for genetic variation within a population. Meiosis supports genetic variation in several ways. All BUT ONE applies to meiosis, sexual reproduction and genetic variation. A) Meiosis is preceded by DNA replication of chromosomes in the nucleus of the mother cell. B) As seen in the diagram, during meiosis crossing over, or swapping of DNA segments, may occur. C) During fertilization each parent randomly contributes a unique set of chromosomes to the zygote. D) Because of recombination and independent assortment during meiosis, each of the four gametes contains a different set of DNA. Not GradedThe term heterozygous means; a) An organism has two different sex chromosomes Ob) An organism was originally twins that fused together in the zygote stage c) An organism has two identical alleles for a given gene d) An organism has two different alleles for a given gene1)Ganarles contain one kind of each chromosome because the homologous chromosomes separate during meiosis.
