Answer: Haploid cells have 23 chromosomes while diploid cells have 46 (23 pairs) chromosomes
Explanation: Haploid cells are produced in a type of cell division called meiosis. In meiosis, parent cells undergo two cell divisions to produce four daughter cells with half the number of chromosomes in the parent cell. Diploid cells are produced by a type of cell division known as mitosis. In mitosis, parent cells undergo one cell division to produce two identical daughter cells that have the same number of chromosomes as the parent cell. Gametes undergo meiosis while somatic cells undergo mitosis.
The DNA of any individual possesses genetic traits which vary from individual to individual. Traits can be physical traits or behavioral traits. Example of a physical trait would be the appearance of an individual and behavioral trait refers to the nature of the individual. Both vary from individual to individual.
Answer:
Science has to do with life, space, and physics and technology has to do with electronics
Explanation:
Both are different because of their name, technology has to do with tech and science has to do with everything going on around us
Answer:
Types of variation in genetics
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring)
other answer
There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population. Because of this, mutations are usually selected against through evolutionary processes
