Answer:: Jade's error occurs in the top-right square of the Punnett square. In this square, she identifies the phenotype as freckles, but to have freckles, the offspring must have at least one dominant allele. The offspring in this box are ff. Because there is no dominant allele present, the offspring will not have freckles.
Explanation: Did the assignment
Answer:
Genetic drift.
Explanation:
Genetic variation is the change in the genome of the organisms. The genetic variation might occur in the population due to the natural selection, mutation and genetic drift.
As the information given in the population, the variation is possible due to the genetic drift. This mainly occur due to the random sample of the small population and might cause the complete loss of the particular gene. The genetic variation might decreases in the organisms.
Thus, the answer is genetic drift.
Answer: The sequence of events of avocado seed germination includes:
Water absorption --> enzyme activation --> radicle emerges --> lengthening of the hypocotyl --> growth of epicotyl and plumule development --> shrinking of the cotyledons.
Explanation:
Germination is defined as all the changes that occurs when a seed embryo resumes it's growth and development to become an independent seedling. Seeds usually germinate in two ways:
--> EPIGEAL germination: in this type of germination, the hypocotyl grows rapidly and elongates, carrying the cotyledon above the soil.The AVOCADO seed is a typical example of a dicotyledonous plant.
The sequence of events of avocado seed germination starts by imbibition which is the rapid in take or absorption of water by the seed through osmosis. Hydration of the embryo activates the enzymes in it which converts insoluble stored food materials into soluble forms. The testa splits and the radicle emerges first. It grows downwards as the primary root from which root hairs and branch roots arise( to form a tap root system). Next, the hypocotyl lengthens, pushes its way up through the soil carrying with it the cotyledons and the plumule. The cotyledons turn green on exposure to sunlight and start to photosynthesize. The epicotyl then grows and the plumule develops into a green shoot. By the time the first foliage leaves grow and begin to photosynthesize, the cotyledons shrink and drop off.
Cancers develop usually by damage to the DNA or by genetic predisposition. With concern to the pathophysiology of cancers or malignancies by genetic predisposition; the two hit hypothesis explains how inherited traits lead to cancer development. The first hit is the inherited susceptibility gene wherein alone, will not cause cancer development. The second hit is usually caused by DNA damage brought about environmental factors (i.e. carcinogens). When the two hits are present, there will be cancer development. This hypothesis usually apply to the mutations in tumor suppressor genes rather than oncogenes (genes that promotes cancer development when activated).
