Write a reflection/conclusion about the occurrences of certain hereditary traits, observing similarities or differences in traits between parents and offspring, and identifying which trait is dominant or recessive.

When two different alleles that affect the same trait do not exhibit complementation, an interpretation is that     the alleles occur in the same gene.     the alleles occur in two different genes.     both alleles are recessive.     one allele is dominant and the other is recessive.     both alleles are dominant.

The father of three sons and two daughters begins to show symptoms of Huntington disease. What is the probability that Sam, the man’s second oldest son (II-2), will suffer from the disease if he lives a normal life span? Sam’s mother and her ancestors do not have the disease. Sam's father was adopted, so we do not know his biological family history for Huntington disease. Explore all possible outcomes for Sam and explain your reasoning. What about the risk to Sam's sisters? Would that be the same or not?

Please read the scenario below and answer the question (in bold) that follows: Spider-Man and Spider-Woman are planning to have children in the near future. Spider-Man is able to spin webs (S) and cling to walls (C), whereas Spider-Woman can spin webs but cannot cling to walls. If both of these traits are inherited in a dominant manner (i.e., the dominant trait will always mask the recessive trait), Spider-Man is heterozygous for each trait, and Spider-Woman is heterozygous for the web-spinning trait...   What would be the phenotypic ratio of the F1 generation? Please note that: "S" = ability to spin webs; "NS" = cannot spin webs; "C" = ability to cling to walls; and "NC" = cannot cling to walls.   a. 2 S/C : 6 S/NC : 6 NS/C : 2 NS/NC   b. 4 S/C : 4 S/NC : 4 NS/C: 4 NS/NC   c. 8 S/C : 2 S/NC : 2 NS/C : 4 NS/NC   d. 6 S/C : 6 S/NC : 2 NS/C : 2 NS/NC   e. None of the above
