2. Both sexes of adults and tadpoles are present. 3. The chromosome number is diploid and probably 26 in both sexes.
Are frog cells diploid?
If a frog cell had 26 chromosomes, then the cell is diploid or haploid (circle one). If a housefly cell had 6 chromosomes, then the cell is diploid or haploid (circle one).
What is the haploid number for frogs?
Edible frog is the fertile hybrid of the pool frog and the marsh frog. 26 autosomes and varying number of the sex chromosomes from three (X1X2Y) to 21 (X1X2Y+18 extra Xs). 32 for females (2n = 32), males are haploid and thus have 16 (1n =16).
Are humans diploid or haploid?
Humans have 46 chromosomes in each diploid cell. Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes. The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).
Is a frog sperm haploid or diploid?
In all-hybrid populations consisting of diploid (LR) and triploid (LLR and/or LRR) frogs, diploid individuals also produce gametes clonally (1n in males, 2n in females), whereas triploids eliminate the genome they have in single copy and produce haploid gametes containing the recombined other genome.
Is a frog a haploid?
The chromosome number is diploid and probably 26 in both sexes. … The chromosome numbers observed by other authors in parthenogenetic frog material are haploid, diploid, and variable.
Which animal has highest number of chromosomes?
The mitotic and meiotic chromosomes of the semiaquatic rodent Ichthyomys pittieri (Rodentia, Cricetinae) from Venezuela were analyzed by means of conventional staining and several banding techniques. The diploid chromosome number of this rare species is 2n = 92, which is the highest value known for mammals.
What if a person has 47 chromosomes?
A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.
