Chapter 8: Problem 26

What is endopolyploidy? What is its biological significance?

Short Answer

Expert verified
Endopolyploidy is a condition in which parts or all of a cell's genome is replicated without a corresponding cellular or nuclear division, resulting in cells with multiple chromosomes. It plays a significant biological role in cell growth, differentiation, organ development and is also thought to aid in species evolution.

Step by step solution

01

Understanding the term 'endopolyploidy'

Endopolyploidy is a condition in which a part or all of a cell's genome is replicated without a corresponding nuclear or cell division. This results in cells with a multiple of the haploid number of chromosomes.
02

Understanding the process of endopolyploidy

This process can occur several times within a cell, each time doubling the number of copies of the genome. It often results in cells with many copies of their genome.
03

Biological significance of endopolyploidy

Endopolyploidy has significant biological importance. It occurs naturally in many organisms, including humans, where it can be seen in liver and muscle cells. It aids in cell growth, differentiation, and organ development. It is also thought to play a role in the evolution of new species, as organisms with greater genomic variation have more potential for adaptation.

An inversion heterozygote has the following inverted chromosome: What would be the products if a crossover occurred between genes \(H\) and \(I\) on the inverted chromosome and a normal chromosome?

A zookeeper has collected a male and a female lizard that look like they belong to the same species. They mate with each other and produce phenotypically normal offspring. However, the offspring are sterile. Suggest one or more explanations for their sterility.

The karyotype of a young girl who is affected with familial Down syndrome revealed a total of 46 chromosomes. Her older brother, however, who is phenotypically unaffected, actually had 45 chromosomes. Explain how this could happen. What would you expect to be the numbers of chromosomes in the parents of these two children?

With regard to the segregation of centromeres, why is adjacent- 2 segregation less frequent than alternate or adjacent-1 segregation?

A woman who is heterozygous, \(B b\), has brown eyes; \(B\) (brown) is the dominant allele, and \(b\) (blue) is recessive. One of her eyes, however, has a patch of blue color. Give three different explanations for how this might have occurred.
