The original roots of dodder usually die. As a parasitic plant that cannot produce its own chlorophyll, it breaks away from its root system as the roots has no apparent root cap nor apical meristems. Hence the "root" is not performing its very function of water and nutrient uptake. It then produces haustoria, a root-shaped fungi which penetrates host plant which makes the dodder parasitic.

Answer:
See the answer below
Explanation:
Let the disorder be represented by the allele a.
Since the disease is an autosomal recessive one, affected individuals will have the genotype aa and normal individuals will have the genotype Aa or AA.
Since the four adults are carriers, their genotypes would be Aa.
Aa x Aa
Progeny: AA 2Aa aa
Probability of being affected = 1/4
Probability of being a carrier = 1/2
Probability of not being affected = 3/4
(a) The chance that the child second child of Mary and Frank will have alkaptonuria = 1/2
(b) The chance that the third child of Sara and James will be free of the condition = 3/4
(c)
(d) If someone has no family history of the disorder, their genotype would be AA.
AA x aa
4 Aa
<em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history </em>= 0
(e)
(f) <em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history</em> = 0

Answer:
The answer is C (UAAGCUCGU)
Explanation:
T is replaced by U in RNA and A and U "bind". In this case, we're looking for the complementary RNA strand, so all terms are opposite; G becomes C, A becomes U, etc.
