The answer is crossing over. Sister chromosomes of the homologous chromosomes exchange parts of their arms after forming an attachment joint called a chiasma. This results in recombination of genetic material between the attached chromosomes. This phenomenon is responsible for increased variation in the offsprings from the formed gametes

Answer from: destiniout04231

Chromosomes exchange genetic information during prophase I by a process called cross over. This process occurs in the first division of meiosis in prophase I, where two chromosomes of a homologous pair exchange segements with each other. It creates new combinations of genes in the gametes that are found in either parent and therefore contributing to what we call genetic diversity or genetic variation among organisms.

Answer from: Quest

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
