12. Color-blindness is a x-linked recessive disease. Under what circumstances will this condition manifest in a child? If the child is a male and its mother has the recessive allele. If the child is a female and its father has the recessive allele. If the child is a female and its mother has the recessive allele. If the child is a male and its father has the recessive allele. 13. In fruit flies, the allele for vestigial wings is recessive to the allele for normal wings. In a generation of fruit flies, 18 males and 15 females with vestigial wings are produced, and 43 males and 44 females with normal wings are produced. Which of the following is the best conclusion you can make about the parents of this generation? Both parents were heterozygous for wing type. One parent was heterozygous for wing type and the other was homozygous with normal wings. Both parents were homozygous with normal wings. One parent had vestigial wings and the other was heterozygous for wing type. 14. In a cell that is undergoing mitosis, sister chromatids have aligned along the cell's equator, and spindle fibers have attached to the centromeres of the sister chromatids. Which of the following processes will the cell enter next? Metaphase Telophase Anaphase Prophase 15 While mRNA strands are being created a sequence is sometimes miscopied. What will be the effect of this on the cell? The damaged mRNA may cause cell death. Translation may not take place. Future transcription will not take place. Ribosomes may be destroyed. 16 A body cell has been growing and synthesizing proteins. In the nucleus of this body cell, DNA replication is taking place, and a copy of the cell's genetic material is copied. Which of the following is the best conclusion you can make about the life cycle of this cell? The cell is ready to undergo mitosis, and a chemical signal will send the cell to prophase. The cell is undergoing meiosis and will cross over the genetic material next. The cell is in the S phase of interphase and will move next to the G2 phase. The cell is in the G2 phase of interphase and is ready to begin dividing. 17 In pea plants, the allele for yellow seeds is dominant to the allele for green seeds. If a plant that has heterozygous yellow seed is crossed with one that has only homozygous green seeds, what percent of their first generation offspring would you expect to have green seeds? 50 percent 100 percent 0 percent 25 percent 18 If a mutation occurs in a body cell and the mutation changes the phenotype of the individual, what will happen to the offspring of the individual? The offspring may or may not inherit the new phenotype. The offspring will inherit neither the genotype nor the phenotype change. The offspring will inherit the new phenotype. The offspring will inherit the change in genotype but not the phenotype change. 19 A person with the genetic disorder Klinefelter's syndrome has an extra x-chromosome. Affected individuals have the genotype XXY. What can you infer is most likely the genetic mutation that results in Klinefelter's syndrome? Complete duplication of chromosomes during polyploidy Non-disjunction during meiosis Translocation during genetic replication Crossing over during meiosis 20 A plant breeder found a species of flowering plant with very attractive flowers growing wild in a field and she thought it would appeal to her customers. Some of the plants of this species had red flowers, some white flowers, and some pink flowers. While she would like to be able to offer her customers all three colors of flowers, she only has permission from the landowner to dig up one plant to bring back to the nursery as breeding stock. What would be the best thing for her to do? Take a white flowering plant since the white allele could be masking the pink allelle. Take a pink flowering plant since it is likely to carry both the red and white alleles. Take a red flowering plant since it could produce all three colors eventually. Take a red flowering plant since the red allele is likely the dominant one.  21. Many organisms can reproduce asexually through mitosis, while other organisms reproduce sexually, and their cells carry out meiosis to form gametes. In a situation where an organism falls prey to many efficient predators, which of these processes would be most beneficial to a species? Meiosis: numerous daughter cells produced would increase the species' population. Meiosis: genetic variation would reduce the species' survival. Mitosis: numerous offspring would increase the odds that some of them would survive. Mitosis: numerous genetic mutations would help some individuals of the species.

14 is anaphase
15 is a
16 is the third one
17 is 25 percent but I'm not too sure
18 is the second one
19 is i think the second one. not too sure.
20 is the second one
and uh not too sure on 21
Ok thank you so much
No problem
17. Is 50% D = yellow d = green D D d Dd Dd d dd dd
