In sexually reproducing species, the events of meiosis and fertilization directly result in a constant number of chromosomes in body cells from one generation to the next. During meiosis, the chromosome number is halved to produce gametes, while fertilization restores the diploid number by combining two haploid gametes. This cycle ensures that the diploid number of chromosomes is maintained in the offspring, keeping it consistent across generations.

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.


How is crohn's disease passed from generation to generation is it sex linked what chromosome is it on and is it on the X or Y?

Crohn's disease is not directly passed from generation to generation in a simple Mendelian fashion; rather, it has a complex genetic component influenced by multiple genes and environmental factors. It is not sex-linked and does not reside solely on the X or Y chromosome. Genetic predisposition can be inherited, but the exact mechanisms and specific chromosomes involved are still being researched, with multiple loci identified across different chromosomes.


Are homologous chromosomes involved in the process of mitosis?

No, homologous chromosomes are not directly involved in the process of mitosis. Mitosis involves the division of a cell's replicated chromosomes into two identical daughter cells. Homologous chromosomes are pairs of chromosomes that carry similar genetic information but are not directly involved in mitosis.

If y equals kx then what is the relationship between x y and k?

Various options: y is directly proportional to k, with x as the constant of proportionality; y is directly proportional to x, with k as the constant of proportionality; x is inversely proportional to k, with y as the constant of proportionality; x is directly proportional to y, with 1/k as the constant of proportionality; k is directly proportional to y, with 1/x as the constant of proportionality; and k is inversely proportional to x, with y as the constant of proportionality.
