Scientists working in the fields of both genetics and archaeology have made discoveries that help us understand the origin of ma

ize. Which statement(s) best reflect the way(s) each discipline's work support evidence generated by the other?
Select all that apply.
a. Geneticists used DNA data to determine how long ago maize was domesticated. Archaeologists then verified the conclusion by dating maize microfossils.
b. Archaeologists first determined where maize was first domesticated. From there, geneticists calculated how long ago that was.
c. Genetics data pinpointed the likely location of the earliest maize domestication, which allowed archaeologists to find fossil evidence of early maize in caves.
d. Geneticists used archaeological data to identify how many genes controlled the changes from teosinte to maize.

A mutation in a gene for normal production of plant chlorophyll results in a plant without chlorophyll. Explain the consequences
Nezavi [6.7K]
A plant without chlorophyll would not be able to photosynthesise because chlorophyll serves to absorb sunlight, which is used to break apart the bonds in water during photosynthesis. A plant that is unable to photosynthesise is not able to create glucose, hence it would likely die unless it was receiving glucose through another source. This is because the plant relies on the energy it gets from breaking down glucose for important internal functions.

In the pea plant, the allele for green pod color (G) dominates the allele for yellow pod color (g). The Punnett square illustrat
kherson [118]
The  offspring  that  can be  described  by  the genotype  is  Gg   while  for the  phenotype  is  green  pod color

  The cross between  GG  and  gg  give   a  heterozygous  offspring  that Gg  offspring.    The  offspring  are  have a green  pod  color  since  the   green  pod  color  is dominant over  yellow  pod  color    and  therefore  the offspring  have  a  green  pod color. The  cross  is  as the  punnet square  below.

Restriction enzyme HinfI cleaves a five nucleotide DNA sequence GA(A/T)TC. The ambiguity in the central position - (A/T) - means
Afina-wow [57]

Answer:

C) 2.0 kb

Explanation:

It is given that out of the 4 nucleotides A, T, C & G each one has equal probability to occur at any position on the DNA molecule which simply means that the probability of occurrence of any nucleotide at a position is 1/4.

Also, it is given that probability of occurrence of either A or T at 3rd position is equal which means that the probability at that particular position will be 2/4 = 1/2.

Now, GA(A/T)TC is the DNA sequence where Restriction enzyme HinfI cleaves so the total probability of an average HinfI cleavage fragment will be = 1/4 x 1/4 x 1/2 x 1/4 x 1/4 = 0.00195 = 0.2 i.e. 2 kb.
