What is an important factor in increasing variety among sexually reproducing organisms?
Genetic recombination during meiosis is a crucial factor in increasing genetic variation among sexually reproducing organisms. This process involves the shuffling and exchange of genetic material between homologous chromosomes, leading to offspring with unique combinations of traits.
Which pair of events would directly result in a constant number of chromosomes in body ells from one generation to the next in sexually reproducing species?
Meiosis, which halves the number of chromosomes in the sex cells, and fertilization, where two sex cells combine to form a zygote with a full set of chromosomes, result in a constant number of chromosomes in body cells from one generation to the next in sexually reproducing species.
After meiosis how many chromosomes does each new cell have?
Each new cell produced after meiosis has half the number of chromosomes compared to the original cell, so each new cell will have half the number of chromosomes as the parent cell. This reduction in chromosome number is important for maintaining the correct chromosome number in sexually reproducing organisms.
Mendel's law of segregation applies to what a.all forms of life b. applies to sexually reproducing organisms c.applies to asexually reporducing organism d. only unicellular organisms e. is invalid?
b.applies to sexually reproducing organismsbecause according to Mendel's law of Segregation, TWO alleles for a heritable character segregate (separate) during gamete formation and end up in different gametes, thus an egg or a sperm gets only one of the two alleles that are present in the SOMATIC cells of organisms make the gamete
Are fungi capable of reproducing both asexually and sexually?
Yes, fungi are capable of reproducing both asexually and sexually.
How do gametes return to the diploid number of chromosomes for sexually reproducing organisms?
They merge.
What happen during meiosis?
the process of cell division in sexually reproducing organisms that reduces the # of chromosomes in reproductive cells
Do all sexually-reproducing organisms have the same sex chromosomes as human?
No, not all sexually-reproducing organisms have the same sex chromosomes as humans. Humans possess a XY sex-determination system, where males have XY chromosomes and females have XX chromosomes. Other organisms can have different systems; for example, birds typically have a ZW system, where males are ZZ and females are ZW, while some reptiles and fish may have varied systems. The diversity in sex chromosomes reflects the evolutionary adaptations of different species.
If meiosis did not occur in sexually reproducing organisms?
If meiosis did not occur in sexually reproducing organisms, the chromosome number would double in each generation. Sexual reproduction results in new combinations of genetic traits.
In the organism reproducing sexually what is the number of chromosomes in the nucleus of the somatic cell?
google it.
In sexually reproducing organisms, genes are transferred via _______________?
The gametes.
What is meitoic?
The process of cell division in sexually reproducing organisms that reduces the number of chromosomes in reproductive cells from diploid to haploid, leading to the production of gametes in animals and spores in plants.
What is the cause of variation in the offspring of sexually reproducing organisms?
recombination of alleles
What will happen if cell do not undergo meiosis in sexually reproducing organisms?
There will be no reproduction
What are sources of genetic variation in sexually - reproducing organisms?
meiosisHuman recombination
Where do sexually reproducing organisms inherit their alleles from?
Sexually reproducing organisms inherit their alleles from their parents. Offspring receive one copy of each gene from each parent, leading to genetic variation.
In the cell of a sexually reproducing organsim a pair of similar chromosomes with the same genes in the same locations is known as?
the answer is homologos
