The size of a genome does have affect an animal:

conclusion-

The muscular hypertrophy, or double-muscle phenotype, is a heritable condition in cattle that primarily results from an increase in number of muscle fibers rather than the enlargement of individual muscle fibers, relative to normal cattle. The relative increase in fiber number is observed early in pregnancy and results in a calf possessing nearly twice the number of muscle fibers at the time of birth. The occurrence of double muscling has been observed in several cattle breeds worldwide since it was first documented by Culley in 1807. The breed in which this muscular hypertrophy and its effects have been analyzed most extensively is the Belgian Blue breed, which has been systematically selected for double muscling to the point of fixation in many herds. Domestic animals other than cattle also show dramatic increases in muscle mass. Malignant hyperthermia of pigs with muscular hypertrophy and muscle hypertrophy of cats associated with a dystrophin deficiency have been analyzed at the molecular level.

Procedure

Research Question:

How will the size of an genome affect an animal

1. Go to the animal genome size database at http://www.genomesize.com to begin your experiment.

2.To get an idea of types of animals that are in the database, watch the upper left corner of the website.

3. If there is a scientific name you do not recognize, you can look for more information from the Animal Diversity Web at http://animaldiversity.org (like a common name or a photo).

Now that you are familiar with the data, you need to make a data table for your experiment:

Common Name Scientific Name Category (Bird, Mammal, etc.) Genome Size, C-Value (pg)

Browse through the database of animals and write down any interesting results in your data table. You can conduct your experiment in several ways:

Hypothesis

I think the size of an genome will not have an affect on an animals muscle mass

Backround

IV & DV

To find out what animals has the largest genome, and how does it affect them.

Independent variable:Genomes of animals
