A woman and man have approached you for genetic counseling and are concerned about a hereditary form of deafness in their family. Both have normal hearing and there are no children. The woman's father has autosomal dominant sensory-neural deafness. Assume he is heterozygous. This hearing impairment displays onset at about age 10, and penetrance appears to be about 70%. There is no family history of deafness among the man's relatives. What is the probability that the woman is a carrier of the deafness allele

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
