Check all that apply to the scenario shown in the figure where plant height from genetically identical individuals is evaluated as a function of temperature.



1- Check all that apply to the scenario shown in the figure where plant height from genetically ... Check all that apply to the scenario shown in the figure where plant height from genetically identical individuals is evaluated as a function of temperature.    Temperature influences the growth of plants.    The genotype of the plant is likely altered by the environment.    The environment likely impacts the expression of genes important to plant height.    Plants grow well at 40oC.    Despite having the identical genetics the phenotype of organisms show continuous variation with respect to the environment. 2- Check all that are correct about the inheritance of the ABO blood group in humans as ... Check all that are correct about the inheritance of the ABO blood group in humans as illustrated in the table.    The gene for blood type shows a complete dominance inheritance pattern.    The gene for blood type shows an incomplete dominance inheritance pattern.    The gene for blood type shows a codominance inheritance pattern.    The gene for blood type has two different alleles.    The gene for blood type has multiple (> 2) alleles.    The phenotype for the ABO blood type reflects the types of antibodies produced in the blood stream.    The phenotype for the ABO blood type reflects the type of carbohydrate groups found on the surface of red blood cells.    A person with type O blood will have compatibility with blood from a type A donor. Hint: Antibodies attack antigens or foreign molecules that are not naturally produced by the individual.    A person with type AB blood will have compatibility with blood from a type O donor. Hint: Antibodies attack antigens or foreign molecules that are not naturally produced by the individual. 3- Match the type of inheritance with the statements about the molecular basis of inheritance. 1- Pattern baldness in humans occurs from an allele that is dominant in males and recessive in females (1)incomplete dominance. 2) X-linked inheritance, 3) codominance. 4)sex influenced inheritance. 5) simple mendelian inheritance) 2- B. A women who is heterozygous for the recessive hemophilia gene does not exhibit the disease. Her sons, but not daughters, inherit the disease. (1)incomplete dominance. 2) X-linked inheritance, 3) codominance. 4)sex influenced inheritance. 5) simple mendelian inheritance) 3- . Individuals who are homozygous for the normal gene that encodes an enzyme for metabolizing phenylalanine have low levels of this amino acid, while individuals heterozygous for the mutated gene have intermediate levels of phenylalanine, and individuals homozygous for the mutated gene have very high levels of phenylalanine, and therefore exhibit phenylketonuria. (1)incomplete dominance. 2) X-linked inheritance, 3) codominance. 4)sex influenced inheritance. 5) simple mendelian inheritance) 4- An inheritance pattern that occurs when the heterozygous individual expresses both alleles simultaneously. For example, a human carrying the A and B alleles for the ABO antigens of red blood cells produces both the A and the B antigens (has an AB blood type). (1)incomplete dominance. 2) X-linked inheritance, 3) codominance. 4)sex influenced inheritance. 5) simple mendelian inheritance) 5- E.  A person with Tay-Sachs disease is homozygous for a mutated form of the hexosaminidase A gene (Tay-Sachs allele). This results in little production of the functional hexosaminidase A enzyme, leading to poor lipid metabolism, excess brain lipid deposition and eventual death.  Individuals who are heterozygous for the Tay-sachs allele, produce enough of the hexosaminidase enzyme for proper lipid metabolism, and hence do no exhibit the disease (1)incomplete dominance. 2) X-linked inheritance, 3) codominance. 4)sex influenced inheritance. 5) simple mendelian inheritance)
