Some species have the same chromosome number but they are different. Suggest an explanation?
Some species have same number of chromosomes but they are different. suggest an explanation
What else can I help you with?
Some species have same number of chromosome but they are different .Suggest an explanation?
some species have same number of charosomes but they are different because Fusion is a common way for animal species to end up with a different number of chromosomes from their ancestors.
What might this suggest about the size and organization of chromosomes in different species?
Differences in chromosome size and organization can reflect variations in genetic complexity and evolutionary history among different species. For example, species with larger genomes may have more chromosomes or larger chromosomes. The organization of chromosomes, such as the presence of specific genes or repetitive sequences, can also vary between species, influencing traits and adaptations.
How many chromosomes does a sloth have?
Sloths typically have 32 chromosomes, which is the standard number for the two-toed sloth species (Choloepus). However, the three-toed sloth species (Bradypus) has a different chromosome count, generally around 30 chromosomes. Chromosome numbers can vary slightly among different species within the sloth family.
What is cromosome no of cotton?
The chromosome number of cotton varies depending on the species, but the most commonly studied species, Gossypium hirsutum, has a diploid chromosome number of 26 (2n = 26). Other species, like Gossypium raimondii, also have this diploid count. Overall, cotton plants belong to the family Malvaceae and exhibit a range of chromosome numbers across different species within the genus Gossypium.
Do chromosomes contain all of your dna?
Each chromosome contains a section of your DNA. a human has 23 pairs of chromosomes, and each part contains instructions for different things. The 23rd chromosome is where the sex is decided in humans, as the pair is either XY for a male or XX for a female. Different animals have different chromosome numbers, which is why they cannot breed with different species.
How many chromosomes are in a freshwater clam?
Freshwater clams, specifically the species Corbicula fluminea, typically have 28 chromosomes, arranged in 14 pairs. However, the chromosome number can vary among different species of freshwater clams. It's important to check the specific species for accurate chromosome counts, as this can differ.
What is a z chromosome?
A Z chromosome is a sex chromosome in a species in which the female is heterogametic (i.e. has different sex chromosomes). The counterpart is the W chromosome. In an XY system (e.g. humans), the male is heterogametic, XY, and the female is homogametic, XX. In a ZW system, the male is homogametic, ZZ, and the female is heterogametic, ZW. Examples of species with ZW systems include all birds, many reptiles, fishes and some insects.
Polyploid speciation occurs through?
Polyploid speciation occurs through the duplication of an organism's entire set of chromosomes, leading to the formation of a new species with a different chromosomal count. This can happen through either autopolyploidy (involving duplication within the same species) or allopolyploidy (involving hybridization between different species followed by chromosome duplication).
What Different types of Evidence used when comparing plant species?
Physiological similarities suggest the species evolved from the same ancestor.
How many genes do cells obtain?
The number of genes varies from chromosome to chromosome and the number of chromosomes varies from species to species (from as few as 1 single chromosome per cell to as many 30,000 chromosome pairs per cell). Human cells have 23 chromosome pairs per cell.
How do biographic observations suggest that a modification process caused new species to arise?
Biographical observations suggest that a modification process caused new species to arise in the way that new species are showing up without explanation and with new adaptations to their environment. One example that is widely used is the appearance of opposable thumbs in humans and monkeys.
Why Chromosomes number is used in the identification of species?
Chromosome number is used in species identification because it is a stable and unique characteristic of a species. Variations in chromosome number can indicate genetic relationships between species, and can help distinguish between closely related species. Additionally, chromosome number is often conserved within a species, making it a useful tool for taxonomic classification.
