there are 4 chromosomes in the sex cells of each fly
Answer:
The question is incomplete, the correct question is;
Which statement describes asexual reproduction, but not sexual reproduction? A) New organisms are formed only after fertiliztion. B) A single cell will not develop into a full organism. C) Daughter cells contain half the genetic material of the parent cell. D) Daughter cells contain the same genetic information as parent cells.
Answer is option D. Daughter cells contain the same genetic information as parent cells.
Explanation:
The process in which organisms creates their offspring is called reproduction and the two types of reproduction are asexual reproduction and sexual reproduction.
In asexual reproduction, the offspring are produced from a single parent. They are genetically identical to each other and to the parent. Binary fission, fragmentation, and budding are the different methods of asexual reproduction. Examples of organisms which reproduce through asexual reproduction include bacteria, yeast, amoeba, hydra etc.
In sexual reproduction, the offspring are created by two parents and they are genetically unique. The gametes are reproductive cells present in the parents, produced by meiosis. They are haploid cells containing only half the number of chromosomes. The process in which the gametes from two parents combine to form a zygote (fertilized diploid cell) is called fertilization, where the zygote has twice the number of chromosomes. The zygote develops into a fully formed organism, which has a unique combination of characteristics inherited from both parents.
In the case of the gene that determines high cholesterol in the blood, the two alleles express incomplete dominance.
What this means is that the dominant allele is not completely dominant over the recessive allele. If the allele was completely dominant, even one allele would be enough to determine the individual's trait as dominant. But in the case of incomplete dominance between the alleles, the heterozygous individuals that have one dominant and one recessive allele are an ''in between'' phenotype.
No it would not if the reason or cause of death is already known.
Polyploidy is the state of a cell or organism having more than two paired (homologous) sets of chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes—one set inherited from each parent.
