Answer 1

Answer #1

It is important for D. melanogaster to follow a typical Mendelian cross because of following reasons:

The organism has a simple genotype with comparatively low size of the genome
The genes are located in very close proximity to each other and there are chances of linakge in these organisms
The males and females show a different pattern of genotypes depending upon the make up of their allosomes.
The organism displays a variety of genotypes and hence they must follow the rules of segregation.
The organism is a simple diploid by nature and follows sexual reproduction and thus, in order to maitain its ploidy, it should undergo regular cycle of segregation, recombination and thus follow Mendel's pattern of genetics.

Owing to these reasons, D. melanogaster represents to be one of the ideal invertebrate models to study pattern of genetics.

How do you fill in the boxes? 7.1: Dihybrid Cross in Drosophila melanogaster In this exercise we will be focusing on two genes, one of which controls wing development (ap - apterous and the other controlling body coloration (eb - ebony). Each of these genes has two alleles, where the dominant allele of each produces the wild-type phenotype for their respective trait. When expressed in the homozygous recessive genotype, the recessive allele (ap) for the apterous gene results in a...
