Why are homologous pairs called tetrads?
Homologous pairs are called tetrads because these pairs are maid up of a four-part structure. Tetrad literally means a group of four.
How are analogous and homologous structures different?
They are different because homologous structures have the same structure, but serve a different function. Like mammal arms(human, bat and whales). Analogous structues are different structures, but serve the same function. For example, bat wings and butterfly wings.
How does homologous structure support the theory of evolution?
Evolution is the process of deriving species from other species, forms from other forms. Homologous structures are structures in organisms that share the same components. A good example is the vertebrate limb - it's clear that our arm, a bat's wing, a dolphin's flipper and a mole's digging paw all share the same identifiable bones. This supports the idea they're all derived from a structure in a common ancestor, as opposed to being created independently.
How do analogous structures and homologous structures differ?
Homologous features of animals are a lot more recent in contrast to evolution, where as analogous dates far back. Homologous features are similar in structure, but perform different functions, such as the human hands and dolphin flippers, which makes room to allow recent evolution comparisons while analogous consists of wings of a bee and a bird, which are completely different. When trying to determine evolutionary relationship between two species, biologists concentrate on homologous features, as analogous features would be considered useless in this case.
How do sister chromatids differ from homologous chromosomes?
Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
Body parts similar in origin and structure are what?
homologous
Is the human forelimb a homologous structure?
yes its homologous to a bats wing
What are Structures in different organisms that share a common ancestry?
Homologous structure
Is structure and identical similar?
homologous
What are structures that have different functions in different species but develop from the same embryonic tissue?
Homologous structures
Is a human appendix a homologous structure?
The human appendix (a small sac near the junction of the small and large intestine) is homologous to a structure called the "caecum", a large, blind chamber in which leaves and grasses are digested in many other mammals.http://scienceline.ucsb.edu/getkey.php?key=3246
How would you use homologous structure in a sentence?
I learned about homologous and heterozygous structures in Biology.
What is a similar structure that related species inherit from a common ancestor?
A homologous structure.
What does it mean when dinosaurs have homologous structure?
Two samples are said to homologous, in this context, when they are both very similar in structure and shape and more than likely function.
What is the difference between morphological divergence and homologous structure?
Morphological divergence refers to how different species evolve distinct physical characteristics over time. Homologous structures are similar traits found in different species due to a common ancestor. In essence, morphological divergence can lead to differences in body structures, while homologous structures show similarities in body parts across species.
Does whales and sharks and dolphins have the saem homologous structure?
no.
What homologous structure does the arthropod have for liquid excretion?
Malpighian.
