It has a double-helix shape
Answer:
A. Charles Darwin.
B. Homologous structure
C. Adaptation.
D. Speciation.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
A. Charles Darwin: he developed the theory of natural selection based on certain evidences. Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
B. Homologous structure: it involves similar anatomical structures that are having common ancestry or from the same lineage.
C. Adaptation: it is an inherited trait that allows individuals to survive better.
D. Speciation: it is an ecological and biological process through which new species are formed due to isolation.
The substances that are involved in the control of sperm and egg productions in humans are the Hormones. They play important role in regulating both female and male reproductive cycles. The primary hormones involved in male reproductive system are follicle stimulating hormone, leutenizing hormone and testosterone while in females reproductive system we have Gonadotropin releasing hormone, LH, FSH, estrogen, and progesterone. The entire reproductive systems are dependent on hormones in the stimulation and regulation.
Answer:
in the offspring. F2 showed 4 different phenotypes: the round and yellow traits did not stay linked to each other. Ratios for each trait corresponds to what one would expect from monohybrid crosses. Shuffling of traits occurs before they realign in every possible combination.
Pressure would be my best guess, since no choices were given.
