A female child's parents are first cousins whose fathers are brothers. Each of the first cousins' fathers has a rare genetic disease (that is 100% penetrant) and the child of the first cousins appears to have it also. The genomes of the child, the first cousins, and their fathers have been sequenced and you're analyzing these genome sequences to identify the disease gene. Which of the following should you expect? Check All That Apply Only the autosomes should be analyzed. Both affected brothers and the affected child could be compound heterozygotes for two different rare mutations in the same gene that affect gene function. Both affected brothers and the affected child could be homozygous for the same rare mutation that affects the function of a gene. The two first cousins could both be heterozygous for the same rare mutation also found in the affected individuals. The two first cousins could each be heterozygous for different rare mutations, and their child should be a compound heterozygote.
