Question: If a horticulturist breeding gardenias succeeds in having a single plant with a particularly desirable set of traits, which of the following would be her most probable and efficient route to establishing a line of such plants?
A) Backtrack through her previous experiments to obtain another plant with the same traits.
B) Breed this plant with another plant with much weaker traits
C) Clone the plant asexually to produce an identical one
D) Force the plant to self-pollinate to obtain an identical one.
Answer:
C) Clone the plant asexually to produce an identical one
Explanation:
Asexual reproduction is a mode of production of progeny from a single parent. It does not include the fusion of male and female gametes. Therefore, the progeny obtained from the asexual reproduction is genetically identical to the parent plant and is called a clone. One of the methods of asexual reproduction in plants includes vegetative propagation.
To maintain desirable traits in progeny, one must perform asexual reproduction in the single parent plant with such traits. The asexual reproduction would produce the progeny having all the desirable genetic traits as that of the parent plant.
Answer:
Yes
Explanation:
Homologous structures or similar structural features can be a result of common ancestry. DNA comparison and analysis between the species can be used to identify the common ancestor.
No. The first multicellular organisms appeared during the P<span>aleozoic era.</span>
Answer:
In what phase of cell division does exchange of genetic material between non-sister chromatids, or “crossing-over,” occur? It occurs in prophase 1 of meiosis
Explanation:
In prophase 1 of meiosis there is crossing of genetic material
Answer: The correct answer is b. Syphilis.
Syphilis is a type of sexually transmitted disease and the causative agent is bacteria called Treponema pallidum. There are four stages of syphilis: primary, secondary, latent and tertiary. It is a highly contagious disease.
The disease starts to get spread from sores and the pregnant women can pass the disease to the child and can cause abnormalities or even death of the child. If syphilis is untreated till the tertiary phase, it can lead to problems in heart, blindness, deafness, brain, nerves leading to paralysis and even death.
