How many haploid cells do whales have?
The diploid and haploid numbers approximate to 48 and 24 respectively.
How many chromosomes are in 4 sperm cells?
The second meiotic division then occurs in the secondary spermatocytes to form four equal, haploid ‘spermatids. ‘ These are transformed into spermatozoa by the process of ‘spermiogenesis. ‘ Spermatozoa contain 23 chromosomes. So, the correct answer is ’23.
How many chromosomes are in a sperm and egg cell?
It is a two-step process that reduces the chromosome number by half—from 46 to 23—to form sperm and egg cells. When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46.
Why do sperm have 23 chromosomes?
One set of 23 comes from mom and the other 23 from dad. The egg and sperm cells are an exception–they have only 23 chromosomes each. A sperm from the man combines with a woman’s egg in her womb to make a zygote. The zygote ends up with a total of 46 chromosomes and can now grow into a baby.
What animal has 92 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.
How many body cells does a blue whale have?
A human being is typically composed of about 50 trillion cells; the largest Blue Whale 100 quadrillion.
What animal has the most amount of chromosomes?
The organism with the highest chromosome number recorded in to date is estimated to be 1,440 (or 720 pairs) found in the adder’s tongue fern Ophioglossum reticulatum. Original text presents information as: “to date is 2n = ca.
How many chromosomes do porpoises have?
MAKINO determined the chromosome number as 2n=44 and described the 22 bivalents in male meiosis, including one heteromorphic pair which he select- ed as the sex chromosomes.
