What else can I help you with?
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
What does the offspring of a sexually reproducing organism receives?
One half of each parent's chromosomes, and genetic variation, as opposed to those that reproduce asexually - the cells just split, so each generation afterward is genetically identical to the parent.
If the body cells in an organism have no homologous pairs of chromosomes the organism is most likely to be?
If the body cells in an organism have no homologous pairs of chromosomes, the organism is most likely to be haploid. This condition is typical of organisms that reproduce through asexual means or certain stages in the life cycle of gametes in sexually reproducing organisms. Examples include many fungi and some algae. In such cases, the cells contain a single set of chromosomes rather than pairs.
Where do you usually find haploid numbers of chromosomes?
Haploid numbers of chromosomes are typically found in the gametes (sperm and egg cells) of an organism. These cells contain half the usual number of chromosomes, which is important for maintaining the correct chromosome number in the offspring after fertilization.
What constantly provides new variation for natural selection to act upon in a sexually reproducing popularion?
Firstly, mutation. In a sexually reproducing population recombination ( independent orientation of chromosomes and crossing over in meiosis and random fertilization ) is also a source of variation in populations.
In the cell of a sexually-reproducing organism a pair of similar chromosomes with the same genes in the same locations is known as a pair?
homologous
In the organism reproducing sexually what is the number of chromosomes in the nucleus of the somatic cell?
google it.
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
What will the genetic material of a organism do when it produces sexually?
The genetic material of a sexually reproducing organism evolves for better adaptations.
What does the offspring of a sexually reproducing organism receives?
One half of each parent's chromosomes, and genetic variation, as opposed to those that reproduce asexually - the cells just split, so each generation afterward is genetically identical to the parent.
How do gametes return to the diploid number of chromosomes for sexually reproducing organisms?
They merge.
What is the primary cause of variation in offspring of sexually reproducing organism?
recombination of alleles
What type of cells are produced in the male reproductive system of a sexually reproducing organism?
sperm
What is a zygote on a snail?
A zygote on any sexually reproducing organism is the melding of both male and female gametes.
Where do you usually find haploid numbers of chromosomes?
Haploid numbers of chromosomes are typically found in the gametes (sperm and egg cells) of an organism. These cells contain half the usual number of chromosomes, which is important for maintaining the correct chromosome number in the offspring after fertilization.
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.
What happen during meiosis?
the process of cell division in sexually reproducing organisms that reduces the # of chromosomes in reproductive cells
