Homework Answers
There are 4 genes on the same chromosome. The genotype of the heterozygote is ABCD/abcd.
1.ABCBCD/abcd:- It indicates duplication of a chromosomal region. Here the duplicated region is BC.
2. ABCABCD/abcd:- It also indicates duplication of a chromosomal region. Here the duplicated region is ABC.
3. ABCD/adcb:- It indicates inversion of a chromosomal segment. Here the segment that is inverted is bcd and transformed into dcb.
4. AB/acbd:- It undergoes deletion in one arm where CD segment is deleted and in other arm there is an inversion of the segment bc. So here both deletion and inversion of chromosomal segment took place.
5. ABCD/acbd:- It indicates inversion of the chromosomal segment bc which is inverted into cb.

You have three genes on the same chromosome - A, B and C. Each gene has two alleles in a dominant/recessive relationship. For these genes the homozygous recessive has the mutant phenotype for that trait, the dominant phenotype = wild type for that trait. allele A is dominant to a; phenotype a = mutant for trait a; phenotype A = wild type for trait A allele B is dominant to b; phenotype b = mutant for trait b; phenotype B...
