What animal has 62 chromosomes?
Donkeys
Donkeys have 62 chromosomes.
Is there an animal with 92 chromosomes?
Abstract. 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 animal has 60 chromosomes?

Are there 23 pairs of homologous chromosomes?
S Phase: In each human somatic cell, there are 23 pairs of chromosomes; one chromosome comes from the mother and one comes from the father. These pairs are known as homologous chromosomes or homologues. In total, there are 46 individual chromosomes (23 x 2) in each somatic cell; they are diploid.
What animal has 38 pairs of chromosomes?
Domestic cats have 38 chromosomes, including 18 autosomal pairs and the sex chromosomes, X and Y.
What animal has 27 pairs of chromosomes?
Thus, the male echidna has 27 autosome pairs and 9 sex chromosomes.
What is a male horse with no balls called?
Cryptorchidism is defined as the failure of one or both testicles to descend into the scrotum. This condition is not uncommon in horses, and the retained testicle is usually located within the abdomen or inguinal canal.
