WebThe law of segregation states that the two alleles of a single trait will separate randomly, meaning that there is a 50% either allele will end up in either gamete. This has to do with … WebWe can divide the number of copies of each allele by the total number of copies to get the allele frequency. By convention, when there are just two alleles for a gene in a population, their frequencies are given the symbols p p and q q: p = \text {frequency of}\: W p = frequency ofW = = 13/18 13/18 = = 0.72 0.72, or 72\% 72%.
WebLinked genes are genes that are likely to be inherited together because they are physically close to one another on the same chromosome. During meiosis, chro... WebAnswer (1 of 10): The standard way to detect linkage is to perform a test cross with a double heterozygote. If the genes are not linked, you would expect a 1:1:1:1 phenotypic ratio in the offspring. Any significant deviation from this ratio suggests linkage of the two genes. If you produced an F...
