What is the haploid Number of a Cow?
A cow has 60 chromosomes. At half the number of chromosomes, the haploid number for a cow would be 30.
How does fertilization restores the diploid number of chromosome in an orgaism with a haploid chromosome of 8 how many chromosomes are present in the spermatogonium?
Fertilization restores the diploid number by combining one haploid gamete from the mother with one haploid gamete from the father to form a zygote with the full diploid set of chromosomes. In an organism with a haploid chromosome number of 8, each spermatogonium would have 16 chromosomes because they are diploid cells that undergo mitosis to produce sperm cells with the haploid number.
Does the cow determine the sex of the unborn calf?
No, the male decides the gender of the calf. When the semen meets the egg, if it contains a Y chromosome it is going to be a bull (male) calf because the mother will have provided the X chromosome. Whereas, if the semen that contained an X chromosome fertilized the egg then the result would be a heifer (female) calf.
Can stoneflys bite you?
Stoneflies do not bite humans as they do not have the mouthparts to do so. They primarily feed on vegetation and algae in freshwater environments during their larval stages. If a stonefly were to "bite" you, it would likely be harmless and more of a gentle pinch due to their lack of biting structures.
Who would win a orangutan or a chimpanzee?
In general, a chimpanzee would likely win in a fight against an orangutan due to their strength, agility, and aggressive nature. Chimpanzees are known to have more developed social structures and cooperative hunting skills compared to orangutans, giving them an advantage in physical confrontations.
Which two structures of a frog would most likely have the same have the same chromosomes number?
The two structures of a frog that have the same chromosome number are skin cells and fertilized egg cells. They each have 46 chromosomes.
What chromosome is the sex determining chromosome?
That would be the chromosome number 23. Regarding the [sex] chromosome number 23, the female gametes always have a [haploid] X chromatid, whereas the male gametes are just as likely to possess a [haploid] X chromatid as they are to possess a [haploid] Y chromatid.
The chromosome number in an egg cell nucleus of a plant is 14 What is the normal chromosome number in a root epidermal cell of the same plant?
The normal chromosome number in a root epidermal cell of the same plant would also be 14. This is because both the egg cell and the root epidermal cell are part of the same plant organism, so they would have the same chromosome number.
If a trait is always transmitted directly from a father to all his sons and from those sons to all their son what chromosome would the gene for the character be likely on?
The gene for this trait is likely located on the Y chromosome. The Y chromosome is passed down from father to son, and since only males have a Y chromosome, the trait will only be passed down through male lineage.
Which chromosomes contain highest and smallest number of genes?
The Chromosome that carries the fewest number of Genes would be the Haploid Cells. Also known as Gametes. It is your sex cells. Unlike Diploid cells who have double the amount Haploid only have half. So a simple answer to your question would be Haploid. and Why..Because they have half.
A specie with a diploid chromosome number of 4 if gametes were formed by mitosis rather than meiosis what would happen to the chromosome number of the offspring of these organisms over generations?
If gametes were formed by mitosis instead of meiosis in a species with a diploid chromosome number of 4, the chromosome number of the offspring would remain constant from generation to generation. Mitosis produces daughter cells with the same number of chromosomes as the parent cell, so the offspring would continue to have 4 chromosomes per cell. This would result in no variation in chromosome number over generations.
What is the chromosome number of gamete?
They have half the number of the somatic (parent) cell. So if a parent cell had 46 chromosomes in its nucleus, then its gamete would have 23(one chromosome from each pair).
What would happen if sex cells were not haploids?
The chromosome number would double throughout each generation.
Genes for two different traits that are located next to each other on the same chromosome would most likely be?
Inherited together if they are close enough, a phenomenon known as genetic linkage. This is because the genes are less likely to undergo independent assortment during meiosis due to their physical proximity on the chromosome.
If a cell has a diploid number of 32 what would be the chromosome number of a cell in late prophase 1 of meiosis?
32
What would happen if the chromosome number were not reduced during meiosis?
If the chromosome number were not reduced during meiosis, the resulting gametes would have double the normal number of chromosomes. This would lead to an imbalance in the genetic material when the gametes combine during fertilization, resulting in genetic abnormalities and potentially nonviable offspring.
Why do some traits occur mainly in males even though they can be inherited only from their mothers?
Consider recessive traits on the X chromosome. Women have two of these, so it is statistically less likely that a woman would express this recessive trait and much more likely that it would be masked by a dominate X chromosome. If a male gets a recessive X from his mother ( remember, males have one X and one Y chromosome ) it is going to be expressed as there is no corresponding chromosome to mask it.
