Do all species have the same number of chromosomes?
No, chromosomes vary from species to species. A species is distinguished by individuals that can mate and have young that are capable of producing offspring. The number of chromosomes two individuals have must be the same for this to be possible.
In a species of corn the diploid number of chromosomes is 20. what would be the number of chromosomes found in each of the normal egg cells produced by this species?
In a species of corn with a diploid number of 20 chromosomes, the haploid number, which is the number of chromosomes found in each normal egg cell, would be half of that. Therefore, each egg cell would contain 10 chromosomes. This reduction occurs during meiosis, where the diploid cells divide to form haploid gametes.
What number of chromosomes is contributed by each parent to a cell of a baby?
In humans, each parent contributes 23 chromosomes.In general, each parent of any species contributes the haploid number of chromosomes, which is the number of chromosomes in a single set of chromosomes.
How many chromosomes do birds have?
Nearly each species of bird has its own unique number of chromosomes. It can be very difficult to determine the exact number because many of these chromosomes are highly fragmented into multiple 'microchromosomes.' In short, the answer is: "It depends..."
Why are horses and donkeys consider different species?
because they each have a different number of chromosomes
The number of chromosomes in a nucleus depends upon the kind of organism it comes from?
Yes, that's correct. The number of chromosomes in a nucleus is specific to each species and can vary significantly. For example, humans have 46 chromosomes in each nucleus, while dogs have 78, and fruit flies have 8.
How many chromosomes are in penguins?
There are several species of penguins. A different number of chromosomes can appear in each species. Studied species so far show penguins to have between 30 and 80. Emperor and rockhopper penguins both have 38 chromosomes.
How many chromosomes does a panda have?
The Giant Panda has 42 chromosomes.
In mitosis how many chromosomes are in each daughter cell?
It depends on the species--humans, for example, will have 46 chromosomes in each daughter cell after mitosis, while a dog will have 78. In mitosis, the number of chromosomes in each daughter cell is equal to the number of chromosomes in the interphase parent cell.
How many chromosomes will each nucleus have meiosis 1?
During meiosis I, each nucleus will have half the number of chromosomes as the original parent cell. This is because meiosis I involves the separation of homologous chromosomes, resulting in two daughter cells with a haploid number of chromosomes.
In plants and animals an offspring inherits How Many genes?
The number of genes and number of chromosomes inherited depend on the species. The number of chromosomes a species has is known as the chromosome number. For example, (disregarding polyploidy or polysomy) a human baby has 46 chromosomes, but a horse has 64. Chromosomes usually occur as one of a pair in humans, and so they have 23 pairs of chromosomes. However, it is common in plants to have many sets of chromosomes and so they do not occur in pairs, but in triplets, or as sets of 4, 5 or 6 etc. Some species of strawberries have 7 of each chromosome. The number of genes depends on how long the chromosome is, and each chromosome in each different species will have a different number of genes on the chromosome.
Compare the numbers of chromosomes in different species?
Humans have 46 chromosomes (23 pairs), fruit flies have 8 chromosomes, dogs have 78 chromosomes, and turtles have 50 chromosomes. The number of chromosomes can vary widely among different species and does not necessarily correspond to complexity or evolutionary advancement.
