What evidence do you see in the pedigree illustrated if any, allowing the mode of inheritance for this trait to be deduced as completely vs. incompletely dominant? Do not consider any other information beyond what is shown in the pedigree. Answer in one complete sentence, referring to any individuals in the pedigree who may be informative using generation and individual numbers.

11. What evidence do you see in the pedigree illustrated if any, allowing the mode of inheritance for this trait to be deduced as completely vs. incompletely dominant? Do not consider any other information beyond what is shown in the pedigree. Answer in one complete sentence, referring to any individuals in the pedigree who may be informative using generation and individual numbers.

The pedigree above shows the pattern of inheritance of a vision disorder called
Leber congenital amaurosis, which is due to mutations in a gene on chromosome
19 (filled symbols show affected individuals). Identification of the gene hinged
on mapping it to a precise chromosomal location. Results of a small part of that
mapping effort are shown above, analyzing linkage between a SNP marker on
chr. 19 and the vision disorder in this family. The numbers below each person's
pedigree symbol show what alleles they have for this SNP marker.
Which individual in generation III has inherited a recombinant chromosome?

Expert Solution
Step 1: Introduction

When neither characteristic is wholly superior to the other, incomplete dominance takes place. As a result, two phenotypes may combine when both features are exhibited in the same areas. Each gene has two alleles that an individual inherits from each parent. For a dominant trait, a single copy associated with a dominant allele is necessary for the characteristic to manifest. The dominant allele obscures the effects of the recessive one.
