How many chromosomes are in a alligator cell?
Thus, an alligator sperm cells will have the number of chromosomes present in the somatic cells and it contains 16 chromosomes.
How many chromosomes are in a diploid cell of an alligator if one of its haploid cells contains 16 chromosomes?
Hence,it is haploid in condition. But the cells of stomach are diploid in condition. Hence , 2n = 2 ×16 =32 .
How many chromosomes would be found in the sperm cell of an organism that has 32 chromosomes in their stomach cells?
So in an animal with 32 (2n) chromosomes in somatic cell, number of chromosomes in sperm will be 16 (n).
How many chromosomes do alligator eggs have?
Like the American alligator, the gharial has 16 chromosomes . Unlike organisms with genetic sex-determination systems, crocodilians are not thought to have sex chromosomes . Instead sex is determined by incubation temperature of the egg .
How many chromosomes are in each somatic cell?
There are 23 pairs of chromosomes in somatic cells; one member of each pair is paternal (from the father) and one maternal (from the mother).
How many pairs of chromosomes are in a gamete?
In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23.
What is the diploid number for alligator?
The chromosome number in Alligatoridae (Alligator 2n = 32, and Caiman, Melanosuchus, and Paleosuchus 2n = 42) is more varied than in Crocodylidae (Gavialis and Tomistoma 2n = 32, Mecistops 2n = 30, Osteolaemus 2n = 38, Crocodylus 2n = 30~34).
What is a diploid number of 16 chromosomes?
If a diploid cell contained 16 chromosomes, 8 from the mother and 8 from the father, then the haploid cell, or sex cell, would contain half as much or 8 chromosomes. The term gamete is the scientific name for the sex cell. The male gamete is the sperm cell and the female gamete is the egg cell.
What is the diploid number of the daughter cells quizlet?
A diploid cell that enters meiosis with 16 chromosomes will pass through two cell divisions, producing four daughter cells, each with eight. While a haploid number of chromosomes may be even or odd, a diploid number is always even/ double.
How many chromosomes are in animal cell?
For example, most eukaryotes are diploid, like humans who have 22 different types of autosomes, each present as two homologous pairs, and two sex chromosomes. This gives 46 chromosomes in total.
How many chromosomes are in a animal sperm cell?
The sperm cells have only 23 chromosomes, or half of the usual number.
How many chromosomes are present in each koala sperm cell?
Koalas have 16 chromosomes, differing from the ancestral marsupial 2n = 14 karyotype by a simple fission of ancestral chromosome 2 giving rise to koala chromosomes 4 and 717. We sequenced the complete genome using 57.3-fold PacBio long-read coverage, generating a 3.42 Gb reference assembly.
Do alligators have XY chromosomes?
In crocodilian species—the most studied of which is the American alligator—both low and high temperatures result in females and intermediate temperatures select for males. … Therefore, in this species, there are both XX and XY males, but females are always XX.
How many pairs of chromosomes are in each egg or sperm?
Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are known as haploid.
How many chromosomes does a human have?
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.
