|
|
|
the genes for the traits he studied had to be located on the same chromosome
|
|
|
which gametes combine at fertilization had to be due to chance
|
|
|
genes could not be transmitted independently of each other
|
|
|
only diploid organisms would demonstrate inheritance patterns
|
Detailed explanation-1: -Answer and Explanation: For Mendel’s explanation of inheritance to be correct, b. Whichever gametes combine at fertilization had to be due to chance.-this is because if only gametes with certain traits would fertilize, then the patterns of inheritance would have a varying probability.
Detailed explanation-2: -which gametes combine at fertilization had to be due to chance. homozygous.
Detailed explanation-3: -Mendel’s seminal work was accomplished using the garden pea, Pisum sativum, to study inheritance. This species naturally self-fertilizes, meaning that pollen encounters ova within the same flower.
Detailed explanation-4: -Law of Segregation (biology definition): one of the Mendelian Laws of Inheritance stating that the two members of a pair of alleles separate during gamete formation. Consequently, each gamete contains only one member of every pair of genes.
