A heterozygous tall, round-seed plant is crossed to a double-recessive, short, wrinkled-seed plant.What do we call the frequency at which short round seed and tall wrinkled seed are seen in the offspring?
A) The mutation frequency
B) The meiotic frequency
C) The heterotic frequency
D) The allelic frequency
E) The recombinant frequency

Quizplus · Accepted Answer

The frequency at which short round seed and tall wrinkled seed are seen in the offspring is called the recombinant frequency. This is because when genes are on different chromosomes or are far apart on the same chromosome, they are more likely to recombine during meiosis, leading to the formation of new combinations of alleles in the offspring. The other options (mutation frequency, meiotic frequency, heterotic frequency, allelic frequency) do not accurately describe this phenomenon.
