Flies

Humans and fruit flies share about 60% of their DNA sequences due to similarities in genetic makeup dating back to a common ancestor. However, the functions and organization of these shared genes can differ significantly between the two species.

No, fruit flies do not have blood like mammals do. They have a circulatory system that pumps a combination of nutrients, oxygen, and other fluids throughout their bodies, but it is not considered blood.

It seems like you were cut off, but based on the information provided, it appears the experiment involved studying how different types of food affect the evolution of fruit flies over many generations. The final step may have involved observing changes in the fruit fly populations due to the different food conditions.

Thomas Hunt Morgan used fruit flies because they have a short lifespan, produce many offspring, and have easily observable genetic traits. This enabled Morgan to study inheritance patterns and gene linkage, ultimately leading to the discovery of sex-linked inheritance.

there is genetic variation within the house fly population. The resistant house flies were able to survive the insecticide because they carried genes that made them immune to its effects. Over time, if these resistant house flies survive and reproduce, the overall population may become more resistant to the insecticide.

Patterns of inheritance in humans are more complicated due to ethical considerations in conducting controlled breeding experiments, longer generation times, smaller family sizes, and the inability to control environmental factors that may influence gene expression. Additionally, human genetics involves the study of polygenic traits and complex genetic interactions, which can make it more difficult to identify clear inheritance patterns compared to simpler organisms like peas or fruit flies.

A fly belongs to the class Insecta.

Morgan chose fruit flies (Drosophila melanogaster) for his experiment because they have a short life cycle, produce many offspring, and have easily observable traits like eye color that follow simple patterns of inheritance. These characteristics made fruit flies a good model organism for studying genetics and understanding the principles of heredity.

Fruit flies share many genes with humans and have a short life cycle, making them ideal for genetic research. Studying fruit fly genetics can provide insights into basic biological processes that are conserved across species, helping us understand human genetics and diseases better. By manipulating fruit fly genes, researchers can discover new genes associated with human diseases and potential drug targets.

It showed that the father played an important role in determining the sex-linked traits of offspring.

The gene for fruit fly eye color is located on the X chromosome. It codes for a protein called "eye color," which determines the pigmentation in the eyes of the fruit fly. Mutations in this gene can lead to different eye colors in fruit flies.

Maggots are unlikely to be able to eat through plastic bags due to their lack of mandibles and strong biting structures. However, they may be able to find entry points if the bag is torn or damaged.

Gene G in fruit flies could be responsible for a variety of traits or characteristics, such as eye color, wing shape, or behavior. To determine the exact function of gene G, further genetic studies or experiments would need to be conducted.

Flies play a role in the ecosystem as decomposers, breaking down organic matter like dead plants and animals. They also serve as a food source for other animals like birds and reptiles. Additionally, some flies, like bees and hoverflies, contribute to pollination.

Thomas Hunt Morgan's research on fruit flies provided key insights into the role of genes in inheritance, demonstrating that genes are located on chromosomes. He also discovered the phenomenon of sex-linked inheritance, showing that certain traits are linked to the sex chromosomes. Overall, his work laid the foundation for the field of genetics and helped establish the connection between genes and specific traits.

Flies breed a lot faster, so a single researcher can watch the influence over several generations, which really wouldn't be possible on humans.

Also, the flies can be kept in an almost entirely controlled environment, making it easier to exclude external factors from causing one or the other.

The genotype for a white-eyed male fruit fly is X^wY, where X is the sex chromosome and Y is the Y chromosome. The w denotes the gene for white eyes located on the X chromosome. This genotype indicates that the male fruit fly has a white-eye phenotype due to the recessive white eye allele.

Patterns of inheritance in humans cannot be easily studied in peas or fruit flies because of ethical concerns and the complexity of human genetics compared to the simpler genetics of peas and fruit flies. Additionally, certain traits or diseases that affect humans may not be present in these model organisms. Human genetics also involve interactions with environmental factors, making it more challenging to isolate genetic influences.

The phenotype of a fruit fly refers to its physical characteristics, such as eye color, wing shape, or body size. These traits can be influenced by genetic and environmental factors, and studying them helps researchers understand inheritance patterns and gene function.

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.

If one fruit fly is heterozygous for long wings and the other is homozygous for short wings, the expected percentage of their offspring having long wings would be 50%. This is because when the long-winged parent passes on the dominant long-wing allele and the short-winged parent passes on the recessive short-wing allele, the offspring would have one of each allele, resulting in the offspring having long wings.
