Explanation / Answer

The above pattern is autosomal recessive. That is because in the given pedigree, if we take autosome chromosome as AA and aa where A is dominant and a is recessive, then for an example:

From Ist generation:

Male AA                     x          Female Aa

Progeny would be AA and Aa but both male and female would be affected.

Now the cross is autosomal because in the cross between III-5 and III-6 has produced male and female both progenies ill (IV-5 and IV-6). That is because Y linked trait would not deliver in female progeny and X linked trait of father would not deliver to his son. The trait is recessive because some progenies are carrier only and the diseased progeny would occur if both alleles were present.

Therefore, for filling 78- E is correct, for 79- A, for 80- B tay sachs is known for autosomal recessive. The black and white rounds are carriers; therefore, 81-B is correct. Disease generations are all four generations. the unaffected persons are those who neither carrier nor diseased. Individual do not have disease alleles include those who are carriers too because they are not diseased. The disease allele has originated from I-2 and II-1 individuals.
