When Morgan mated fruit flies with the genotypes xr xr (homozygous for the recessive allele xr) and xry (heterozygous with one dominant allele x and one recessive allele r), the result was a phenotypic ratio that reflected the inheritance of the sex-linked traits. The offspring would exhibit a mix of phenotypes based on the alleles inherited from the parents, with some flies showing traits associated with the xr allele and others showing traits associated with the xry allele. This experiment helped establish the principles of sex-linked inheritance and the role of chromosomes in determining traits.

What was the result when Morgan mated fruit flies with the genotypes?
When Thomas Hunt Morgan mated fruit flies with specific genotypes, he observed deviations from the expected Mendelian ratios, indicating that certain traits were linked on the same chromosome. This led to the discovery of genetic linkage and the concept of gene mapping.
What was the result when Morgan mated fruit flies with the genotypes XrYr and XrY?
When Morgan mated fruit flies with the genotypes XrYr (homozygous for recessive traits on X and Y chromosomes) and XrY (heterozygous for the X chromosome), he observed a 1:1 ratio of offspring. The offspring would consist of XrYr and XrY genotypes, leading to a mix of phenotypes that correspond to the traits associated with those alleles. This experiment helped elucidate the principles of sex-linked inheritance in fruit flies.
Which fruit flies did thomas hunt Morgan use?
thomas hunt morgan studied fruit flies. :)
What was the result when Morgan mated fruit flies with the genotypes X R X r and X R Y?
When Thomas Hunt Morgan mated fruit flies with the genotypes X^R X^r (female) and X^R Y (male), the offspring produced included both males and females. The expected genotypes of the offspring would be X^R X^R (homozygous red-eyed females), X^R X^r (heterozygous red-eyed females), and X^R Y (red-eyed males). All offspring would exhibit the red eye phenotype, as the red eye allele (X^R) is dominant over the white eye allele (X^r). Thus, the results demonstrate the inheritance patterns of sex-linked traits in fruit flies.
Was Morgan the first to use fruit flies in genetics experiments?
yes
Why was Thomas Hunt Morgan important with fruit flies?
Thomas Hunt Morgan was important with fruit flies because he used them to establish the chromosome theory of inheritance, demonstrating that genes are located on chromosomes. His research with fruit flies provided key insights into how genes are inherited and laid the foundation for modern genetics.
Why were fruit flies useful in Morgan's research?
Fruit flies were useful in Morgan's research for several reasons. They have a short life cycle, making it easier to study multiple generations. They have a small genome that is easy to manipulate and study. They also exhibit a wide variety of genetic traits that can be easily observed and tracked.
Which organism did Thomas Hunt Morgan use to study gene mapping?
Fruit flies
Which scientist studied fruit flies?
The scientist that studied fruit flies was Thomas Hunt Morgan. He was born in 1855 and died at the age of 79 in 1945. He was an evolutionary biologist.
Why was Thomas Morgan's work with the fruit flies important?
Thomas Morgan's work with fruit flies was important because it helped establish the chromosomal theory of inheritance. By observing patterns of inheritance in fruit flies, Morgan was able to demonstrate the connection between genetic traits and specific chromosomes, laying the foundation for our understanding of genetics today. His work was crucial in advancing the field of genetics and providing insights into how traits are inherited.
What was the result when Morgan mated fruit flies with the phenotypes XRXr and XRY?
When Morgan mated fruit flies with the phenotypes XRXr (female) and XRY (male), the expected offspring would include XRXR (homozygous female), XRXr (heterozygous female), and XRY (male). This would result in a phenotypic ratio where half of the offspring are females showing the dominant trait (XRXR and XRXr) and half are males (XRY). The specific traits exhibited would depend on the dominance relationships of the alleles involved. Overall, the mating would reveal insights into sex-linked inheritance patterns in fruit flies.
Why was Thomas Morgan and work with fruit flies important?
He gave an understanding of how chromosomes effect heredity.
