This pedigree chart tracks the inheritance of a recessive trait that is not sex-linked. based on the information in the chart, which of the following statements is true? this pedigree chart shows three generations. the individuals are numbered from left to right, starting at the top left of the chart. squares represent males and circles represent females. if the symbol is gray, that individual exhibits the recessive trait. if the symbol is white, the individual exhibits the dominant trait. on the first row there are two couples mated together. the first couple is made up of individuals #1 (recessive) and #2 (dominant). they have four offspring on the second row that all exhibit dominant traits: #5 (dominant), #6 (dominant), #7 (dominant), and #8 (dominant). the second couple in generation #1 is made up of individual #3 (dominant) and individual #4 (dominant). they have three offspring in generation 2: #9 (dominant), #10 (recessive), and #11 (dominant). individual #8 from the first family and individual #9 from the second family mated together and produced three offspring in generation 3. these offspring are #12 (recessive), #13 (dominant), and #14 (recessive). a. individual #11 must be homozygous for the recessive trait. b. individuals #3 and #4 must be heterozygous for the trait. c. individual #2 must be heterozygous dominant for the trait. d. individual #9 must be homozygous dominant for the trait.

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
