The law of independent assortment states that the inheritance of?
A.. Law of Independent Assortment: Mendel deduced the first 2 laws by using a monohybrid cross. This is a genetic cross containing 1 trait. Mendel was lucky in choosing the characteristics he worked with, since the were not linked and found on separate chromosomes. In a dihybrid cross, 2 trait cross, there are many possible chromosome combinations during gamete formation. Each chromosome seems to have a mind of its own when choosing which sperm or egg cell to enter. Each chromosome does not have a mind but the rules of chance take over in determining where they are to go. This is called independent assortment. Let us look at a simple example: RrYy represents one parent with the characteristics R and r for skin texture and Y and y for hair texture. The parent is heterozygous for both characteristics. During gamete formation one of the R's and one of the Y's need to be in each sperm cell. If this does not happen the offspring will have too many Y's or too few R's and visa versa. The possible gametes must have one R and one Y to be effective. RY, rY, Ry, and ry are the only possible combinations allowed. This individual has the possibility of producing any one of these gametes from the original RrYy cell. If the other parent has the same genotype ( arrangement of genes) the gametes would be the same. If a genetic cross were made there would be 16 possible combinations of offspring from that mating. 9 would be dominant for both characteristics, 3 would be dominant for R and recessive for y, 3 would be dominant for Y and recessive for r, and 1 would be recessive for both characteristics. This can only occur if 2 or more traits are being used and they are on separate chromosomes.
Reply:Well I actually took a test with the same exact question and the CORRECT ANSWER is B)HOMOLOGOUS!!!!!!!!! Report It

Reply:A) separate
Reply:Things must be on separate chromosomes to assort independently, according to Mendel (choice a). However, if 2 genes are very far apart, they will sort independently as well, as it is unlikely that a random recombination event will capture both genes simultaneously (indicated a dependent assortment).
Reply:The answer is A, separate chromosomes because the law of independent assortment refers to alleles having equal chance of being inherited and for this to happen the genes must be on separate chromosomes (or be very far apart if they are on the same chromosome). Since the question states that "inheritance of alleles for one trait is not affected by the inheritance of alleles for a different trait," then the question is talking about different genes and so, answer B doesn't fit (different traits could be on homologous chromosomes or could be on separate chromosomes). The law of independent assortment wouldn't work for genes on the same chromosome unless the genes were located very far apart on the chromosomes, so C is not the answer. As for D, the word homozygous refers to the inheritance of the same alleles in the offspring (AA or aa, not AB), so this answer doesn't fit.
