<h2>Answer:
A.) Evolution</h2>
While the above definition describes evolution, photosynthesis is the process organisms use synthesize food: primarily using three variables in the process: sunlight (energy), water, and carbon dioxide (CO2).
Edit: More specifically, Darwin's Theory of Evolution states that organisms change in a series of natural selection.
Edouard van beneden proposed that an egg and a sperm, each containing half the complement of chromosomes found in somatic cells, fuse to produce a single cell called a zygote.
Zygote
A zygote (from the Ancient Greek zygtós, "joined, yoked," from v (zygoun), "to join, to yoke") is a fertilized egg. [1] is an example of a eukaryotic cell produced by the fertilization of two gametes. The genome of the zygote, which is made up of the DNA from each gamete, has all of the genetic material for a brand-new unique organism.
The zygote represents the earliest developmental stage of multicellular organisms. A zygote is produced when an egg cell and sperm cell combine to form a new, distinct organism, as is the case in humans and the majority of other anisogamous organisms. The zygote can split asexually through mitosis in single-celled organisms to create identical progeny.

Answer:
a. Ed/eD
b. RF=0.12
Explanation:
The alleles for genes D/d and E/e are:
- D_: only on neck spikes
- dd: along back spikes
- E_: long spikes
- ee: short spikes
After testcrossing a double heterozygote (DdEe x ddee) there are 4 types of offspring, two of them much more abundant than the other two. The homozygous recessive parent can only produce <em>ed</em> gametes, so the phenotypes of the offspring depend on the gametes that the double heterozygous parent produced.
The offspring was:
- Ed/ed 79
- ed/ed 12
- ED/ed 10
- eD/ed 76
Total: 177
a) This result suggests that the genes are linked. Since recombination is a rare event, the most abundant phenotypes always come from the parental gametes, and the least abundant come from the recombinant gametes.
<u>Therefore, the genotype of the doube heterozygote parent was </u><u><em>Ed/eD</em></u><u>.</u>
b) Recombination frequency (RF) = Recombinants / Total
RF = (12+10)/177
<u>RF = 0.12</u>
