Changes in genes occur when organisms produce?
Changes in genes occur through processes such as mutation, genetic recombination, and gene duplication. These changes can result in variations in traits that can be passed down to offspring through reproduction.
Do most silent mutations occur in the third position of the codon?
Yes, most silent mutations occur in the third position of the codon because it is the most degenerate position where changes are less likely to result in an amino acid change. Mutations in the third position are more likely to be synonymous and not affect the protein sequence.
Evolution of a species could occur as a result of changes in the?
Evolution of a species can occur as a result of changes in the environment, leading to natural selection of traits that provide a survival advantage. These changes can also be driven by genetic mutations that introduce new variations within a population. Over time, these factors can lead to the adaptation and divergence of the species.
At what week in fetal development does the genetic instructions for differential development of male or female gonads occur?
The genetic instructions for differential development of male or female gonads occur around the 7th week of fetal development. During this time, the presence or absence of the Y chromosome determines whether the gonads will develop into testes (male) or ovaries (female).
That extinction can occur because of environmental changes?
Extinction can occur when a species is unable to adapt to rapid environmental changes, such as habitat destruction, climate change, or pollution. These changes can disrupt the delicate balance within ecosystems, leading to a decline in population numbers and eventual extinction. It is crucial to address these environmental challenges to prevent further loss of biodiversity.
What changes have started to occur in the recent years of bullfighting?
Female bullfighters are now common, even in Spain.
How do male cats know when female cats are pregnant?
Male cats can sometimes detect changes in the scent and behavior of female cats that indicate they are pregnant. This can be due to hormonal changes that occur during pregnancy.
What Italian city did changes associated with the renaissance first occur?
Florence
What changes occur when a male cat is neutered?
The cat will suffer a loss of testosterone, which will make it act more like a female cat.
Do you all start out being female?
This is the theory because all femle ova have female chromosomes.. Sperm have male and female chromosomes. If the sperm containing female chromosomes then nothing changes during fertilization. If male chromosomes, then changes take place to cause the cells to produce a male. There is scientific theory that this may be a cause of homosexuality in that the changes do not occur as expected. But this is only theory. --- They don't necessariy start as female, but they do have female organs. It is the presence of chemicals (due to Y chromosome) that forms the male organs from the female organs later on.
Does the mother or the father determine the sex of the offspring?
No, it is the male. The female eggs or ovum only have the x chromosone which develop into a female. The sperm have either an x chromosone or a y chromosone which carries the male sex determination. It is by chance and timing which one fertilized the egg first. If it is a x chrromosone then the offspring is a female. If the y chromosone fertilized the egg, then chemical changes occur resulting in a male fetus. No, it is the male. The female eggs or ovum only have the x chromosone which develop into a female. The sperm have either an x chromosone or a y chromosone which carries the male sex determination. It is by chance and timing which one fertilized the egg first. If it is a x chrromosone then the offspring is a female. If the y chromosone fertilized the egg, then chemical changes occur resulting in a male fetus. It is found in both male and female chromosomes.....found in answer key
What are reflections that occur at changes in impedance?
Return loss refers to the reflections that occur at changes in impedance.
What are commons changes which occur during puberty in male and female both?
height,weight,age,body growth and growth of pubic hair
What are 3 changes that occur in the female body?
Menstruation: The monthly shedding of the uterine lining, resulting in vaginal bleeding. Pregnancy: Changes in hormones and physical changes to support fetal growth. Menopause: The cessation of menstruation and decline in reproductive hormones.
How do you explain the who what when why how?
Who was involved, What happened, When did it occur, Why did it occur, and How did it happen.
What is the monthly cycle of changes that occurs in the female reproductive system called?
The monthly cycle of changes that occurs in the female reproductive system is called the menstrual cycle. This cycle involves the maturation and release of an egg, preparation of the uterus for potential pregnancy, and shedding of the uterine lining if pregnancy does not occur.
What artahe physical change that occur in male and female during puberty?
The physical changes in men are the increase inthe size of testis. In females it is the increase in breast sizes.
