How many homologous chromosome alignments are possible for independent assortment during meiosis?
ad-work [718]

Answer

Two alignments.


Two alignments are possible for independent assortment during meiosis.

Explanation;

-According to the independent assortment ; when two or more characteristics are inherited, individual hereditary factors assort independently during the process of meiosis.

-This results to different traits having an equal opportunity of occurring together.

-It means that during meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment, of homologous chromosomes is random.

Genetic Variation:Question 8
Maurinko [17]

Answer: 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).

By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell.

Explanation:

During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. The chromosomes cross over at points called chiasma. At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.

Convert the volume of CO2 you measured in the glucose reaction to moles of CO2 using the Ideal Gas Law to solve for n. Assume P
olganol [36]
The assumption in this problem is that the gas, CO2, is ideal and that the ideal gas law is applicable such that,
                                     n = PV/RT
We simply substitute the given values to the equation above,
                                 n = (1 atm)(V) / (0.082 Latm/mol.K)(T)
                                           n = 12.20 V/T
