Answer – The force of gravity is
stronger than the force of magnetism.
The attractive force of magnetism
is the force that keeps the nails joined to one another and to the end of a bar
magnet while the force of gravity is the force acting to pull the nails to the
ground. If when Juanita sticks the seventh nail, it falls off the sixth nail,
it means that the force of gravity acting on the seventh nail is stronger than
the force of magnetism acting on it.
I believe the answer is this:
DNA replication is called semi-conservative because half of the original double-helix appears in one daughter strand formed in replication if you need any more help then please comment and let me know ok. :)
Answer:
The genotype of the F1 was wy+/w+y.
Explanation:
One of the given options has a typo: the red eye-brown body offspring count should be 56 instead of 561.
<u>We have two genes with two alleles each:</u>
Red eyes (w+) is dominant over white eyes (w).
Brown body (y+) is dominant over yellow body (y).
The phenotypes of the F2 tesulting from a test cross (F1 x wy/wy) are:
- wy+/ey (white-eye, brown body): 670
- w+y/wy (red-eye, yellow body): 650
- wy/wy (white-eye, yellow body): 38
- w+y+/wy (red-eye, brown body 56
If the genes w and y are linked, two phenotypes in the F2 will be much more abundant than the other two. Recombination during meiosis is a rare event, so the most abundant phenotypes are the parentals (the ones present in the F1 parent).
Every individual in the offpsring has a <em>wy</em> chromosome, as this was the gamete inherited from the test cross individual.
In this case, the most abundant gametes are wy+ and w+y, so the genotype of the F1 was wy+/w+y.
Notice how when recombination occurs in the F1 parent, the recombinant gametes appear: wy and w+y+, which are the less abundant in the F2 progeny.
Black B is dominant over chestnut color b and trotting gait T is dominant over pacing gait t. The answer is 100%. Since all offspring have at least one dominant black hair allele that overwhelms the brown hair allele, all offspring are expected to have black hair.
Phenotype refers to the physical color of a horse's coat or the way genes are expressed. Phenotype II FMF in Familial Mediterranean Fever is the onset of amyloidosis prior to the onset of his FMF with typical attacks or is an isolated finding in members of the FMF family.
White horses have pink skin. White fur mane tail, and hooves. and dark brown eyes. White is the dominant trait W at the white locus. White horse genotype must be heterozygous dominant We. Homozygous dominant because WW is more likely to cause early embryonic loss. Scientists conclude that horses were first domesticated 6,000 years ago in the western part of the Eurasian steppe, in what is now western Ukraine and Kazakhstan.
