If we follow 4 genes, where genes A, B, C, and D are on the same chromosome, then in a normal diploid organism we could represent the genetic information present as:
AA BB CC DD
What has happened if now the genetic information is A BBB CC DD?
Select one:
a. deletion
b. translocation
c. duplication
Homework Answers
Duplication
Duplication is self-explanatory from the term. The chromosome that face duplication will have additional copy of the genome. There is an extra genetic material from the duplicated segment. Duplication is opposite of deletion.

1. In humans, red-green color-blindness is a sex-linked (carried on the X chromosome) recessive trait. If a woman who is not color blind but whose father was color-blind marries a man who is not color-blind, what is the probability that their first child will be a daughter who is color- blind? a) 0 b) 25% c) 50%- d) 100%- e) cannot tell from the information given 2.

There are three genes - A, B, C - on the same chromosome. You have been studying gene A and know that the distance between A and B is 5 m.u. (map units), and the distance between A and C is 3 m.u. Based on the information you have, above, what are potential arrangements of all three genes on the chromosome? You can choose more than one. Note: answers give the genes and map units between them, in order. For...

For Drosophila, let’s consider three genes a, b, and c. We know where a and b are located, and have a nice idea about c. You conduct a three-point cross to figure it out for sure. We’ll use a, b, & c to refer to the three mutants, and + to refer to the wild-types. Here are the progeny counts from a heterozygote by homozygous mutant wild-type: a, b, c: 770 +, +, +: 384 a, +, +: 80 +,...
