Please fill in the information below. NAME EMAIL PHONE NUMBER 1. FF-striped fur, Ff- solid fur, ff- spotted fur Two larkeys with solid fur mate. Which fur will their offspring most likely have? Spotted Striped Solid 2. All human BODY CELLS contain this many chromosomes 23 45 46 8 3. Fish is invertebrates. False True 4. What does homozygous mean having two identical alleles of the same gene an allele that is only expressed if there is no dominant allele present one out of the two or more versions of a gene 5. Find the correct meanings of the definition; species compromising of several genera compromising of several classes animalia, plantae, fungi, protoctista and prokaryatae groups of organisms that have many features in common 6. What is the cross breed of a horse and a donkey calf horkey alien mule 7. Adaptations are the characteristics of an organism that enable it to survive in its environment True False 8. Cystic fibrosis and sickle cell disease are examples of Pedigree analysis Monohybrids Inherited recessive genetic disorders Osmoregulation 9. Three children of a family have blood groups A, AB and B. What could be the genotypes of their parents? IˆA IˆA and i i IˆB IˆB and IˆA IˆA IˆA i and IˆB i IˆA IˆB and i i 10. Darwin considered variations in a population to be the raw materials of evolution. True False 11. A woman that is a carrier of colorblindness mates with a man that is colorblind. What percent chance will their offspring actually be colorblind? None of the above 25% 75% 50% 12. What is Continious variation there are no intermediates, but rather distinctly different groups is acquired characteristics caused by environmental factors this is when characteristics are spread over a range of values inherited characteristics caused by mutation or reproduction 13. Which of the following processes allows for cells to divide to produce new cells that contain all of the necessary information to survive? MRNA translation DNA transcription DNA Replication Cellular Reproduction 14. Why are viruses considered as non-living Because they dont have a nucleus They act like parasites Because they dont meet the criteria of the "7 ways of life" They are made up of cells 15. Darwin's observation that there were Patagonian hares but no rabbits in South America was most closely related to his consideration of Comparative anatomy. Comparative embryology The fossil record. . Biogeography. 16. A recessive gene always shows itself. False True 17. The process of diffusion accounts for what percent of a society’s cultural inventory on average? 75% 10% 90% 25% 18. In humans, having freckles (F) is dominant over not having freckles (f). The inheritance of these traits can be studied using a Punnett square similar to the one provided. Refer to the illustration provided. The genotype represented in box 1 in the Punnett square would: Be homozygous for freckles Have freckles chromosomes. Be heterozygous for freckles. Have an extra freckles chromosome. 19. Sex-linked traits are not passed through the x and y chromosomes. True False 20. The type of gene that always shows itself is called a Recessive gene Dominant gene Homozygous gene Powerful gene 21. Tomato plants usually have hairy stems. Hairless stems are present in tomato plants that are homozygous recessive for this trait. If the stem characteristics are determined by a single gene, what is the expected outcome of crossing two tomato plants that are heterozygous for hairy stems? 100% hairy stems 50% hairy stems: 50% hairless stems 75% hairy stems: 25% hairless stems 100% hairless stems 22. When alleles from each parent both appear in an offspring, it is called Codominance Incomplete dominance Complete dominance Coordination 23. Genes of a flower colour in Mirabilis jalapa show incomplete dominance. In a cross between red and white flowered plant, all the F, plants are pink flowered. If these plants are self pollinated, the phenotypic ratio in the F 2 generation will be 3 : 1 1 : 1 1 : 2 : 1 9 : 3 : 3 : 1 24. What does a DNA structure look like? A twizzler A braided rope A long stick A twisted ladder 25. The difference between a monohybrid cross and a dihybrid cross is that Monohybrid crosses involve self-pollination, while dihybrid crosses involve cross-pollination. Monohybrid crosses involve traits for which only one allele exists, while dihybrid traits involve two alleles. Monohybrid crosses involve one trait; dihybrid crosses involve two traits. Dihybrid crosses require two Punnett squares; monohybrid crosses need only one. 1 out of 25 Time is Up! Time's up
