In a monohybrid cross how many traits are examined? How many autosomal genes are there? How many alleles are needed for an autosomal dominant trait to be expressed? How many alleles do polyploids have? What is the probability of getting a fruit fly with the genotype RR if the parents' gen...
Shotgun SequencingThe largest contiguous stretch of DNA yet sequenced in Drosophila suggests that fruit-flies have only half as many genes as Caenorhabditis elegans .doi:10.1186/gb-2000-1-1-reports015Gilean McVeanBioMed CentralGenome Biology
For the fruit fly, the diploid number is8, which can be written as 2N = 8, where N represents twice the number of chromosomes in a sperm or egg cell. Some cells contain only a single set of chromosomes, and therefore a single set of genes. How many chromosomes are there in fruit fly?
How many pairs of chromosomes do humans have, and the total number of chromosomes? How many chromosomes are present when meiosis I starts? Somatic cells of the fruit fly have 8 chromosomes. How many sex chromosomes are present in a fruit fly sperm cell?

Surprisingly, the number of human genes seems to be less than a factor of two greater than that of many much simpler organisms, such as the roundworm and the fruit fly -- see table showing number of genes for different organisms.

among biologists because their genes and chemistry are relatively easy to manipulate, and because they can be easily and quickly bred. And since evolution highly conserves key biological events, what is learned in flies can shed light on the development of many species, including humans, Andrew ...
For example, in the DNA of fruitfly Drosophila melanogaster there are several conserved loci that do not encode any functional genes, but instead contain mutated copies of some TEs [19]. These loci are transcribed in both sense and antisense orientations, which results in generation of large ...
How many chromosomes are in Ophioglossum? number of chromosomes Ophioglossum reticulatum has1,440 chromosomes, the highest number of any organism known to science. Why is Ophioglossum called tongue fern? The adder's-tongue fern is so-namedbecause the tall stalk that bears its spores is thought to...
