What is the penetrance of this trait? i.e., What is the ratio between the number of individuals in the pedigree who display the trait (numerator) and the number of individuals you know from the pedigree must have the trait-determining genotype (denominator)?

The following pedigree represent a disease that is very rare in the human population and completely penetrant. What is the mode of inheritance? What is the probability that a child indicated with an "A" will inherit the disease? SHOW YOUR WORK. A? Enr the toolhar prees Al T+F10 (PC)gr ALT+EN+F10 (Mar)

Joseph is heterozygous for the traits F (dominant to f) and B (dominant to b)and his genes are in cis, and these locuses are on the same chromosome and separated by 30 map units. Sara is also heterozygous for these traits but here genes are in trans. Calculate how likely it would be to observe an individual who is homozygous dominant for the genes F and B. Be sure to show your work for full credit.

A family tree of sorts is called a pedigree. The symbols used for a pedigree are: female, unaffected female, affected ☐male, unaffected male, affected I 11 III 1 Pedigree Chart Minor Peta #2 Siblings are placed in hirth order from left to right and are labeled with Arabic numerals. Each generation is labeled with a Roman numeral. Therefore, the male exhibiting the trait in the pedigree below in the bottom, center would be identified as III-4. 1. Which members of the family above are affected by Huntington's Disease? 4. How many girls did II-1 and 11-2 have? 3. How many children did individuals 1-1 and 1-2 have? 2. There are no carriers for Huntington's Disease- you either have it or you don't. With this in mind, is Huntington's disease caused by a dominant or recessive trait? 5. How are individuals III-2 and II-4 related? 8 -Huntington's Disease
