Chapter 10.2, Problem 2CC
Summary Introduction
To determine:
The number ofpairs of chromosomes and set present in the karyotype as refer to Figure 10.3 “Research method”, in the textbook.
Introduction:
Karyotyping is a technique which is used to study the chromosomal aberration. In this study the detector analyze the structure of the chromosome.

Students have asked these similar questions
In the karyotype shown here, identify the sex chromosomes. Is this individual a male or a female?
Why is a karyogram arranged from largest to smallest? What would happen if it was arranged from smallest to largest?
In a diploid organism of 2n=10, assume that you can label all the centromeres derived from its female parent and all the centromeres derived from its male parent. When this organism produces gamestes, how many male and female-labeled centromere combinations are possible in the gametes?

The cabbage (Brassica oleracia) also has a diploid number (2n) of 18. Why is it that if you cross these two species to produce a hybrid with a total of 18 chromosomes in its somatic cells it is sterile, but if you form an allotetraploid (also known as amphidiploid) from these two species it is fertile?arrow_forward
- In a cross between a white-eyed female (ww) and a red-eyed male (w+Y), nearly all the progeny were either red-eyed females (w+w) or white-eyed males (wY). However, about 1 in every 2000 F1 flies had an "exceptional phenotype" and was either a white-eyed female or red-eyed male. How did Bridges explain this unexpected result? A) Crossing over B) Incomplete cytokinesis C) Incorrect synapsis D) Nondisjunction E) Pseudoautosomal regionarrow_forwardWhy is chromosome 21 the smallest and not chromosome 22? considering that a karyogram is arranged from largest to smallestarrow_forwardL, R, P and D are four genes located on the same chromosome in a diploid organism. Map distances between different pairs of genes were determined and the following results obtained. Based on these data, what is the order of the genes on the chromosome? D-R: 35 CM P-D: 5 CM L-R: 10 CM D-P: 30 CM D-L 25 CM P-R: 40 CM Note that only one orientation of the order is given as an answer choice. For example: ABCD has the same order as DCBA, but only ABCD would be listed as a possible answer. So be sure to check both orientations when comparing your gene order to the possible answer choices.

- You cross a true-breeding yellow-bodied, smooth-winged female fly with a true-breeding red-bodied, crinkle-winged male. The red body phenotype is dominant to the yellow body phenotype and smooth wings are dominant to crinkled wings. Use B or b for body color alleles, and W or w for wing surface alleles.(4 points) a) What are the genotypes of the P generation flies? b) What will be the genotype(s) and phenotype(s) of the F1 offspring? c) You discover that the genes for body color and wing surface are linked. You perform a dihybrid test cross between the F1 flies from part (b) with a true-breeding yellow-bodied, crinkle-winged fly. Use the following results of this cross to determine the recombination frequency (%) between the body color and wing surface genes.
