Answer:
33.3 cM
Explanation:
Parent 1: blue shell, long antenna : BBLL
Parent 2: green shell, short antenna : bbll
BBLL X bbll :
F1 : BbLl ( blue shell, long antenna )
BbLl X bbll :
BL/bl = 82 : Parental
bl/bl = 78 : Parental
Bl/bl = 37 : Recombinant
bL/bl = 43 : Recombinant
Total = 240
Recombination frequency = (Number of recombinants/ Total offspring)*100
= (80/240) * 100 = 33.33 %
Map distance = recombination frequency
Hence, map distance = 33.3 cM
Answer:
4600-4500 million years ago, the Earth formed and its crust cooled to become solid. 4500-4400 million years ago, the oldest known thing to have formed on Earth, zircon, formed along with solid crust and oceans. 4200-4100 million years ago, the close of the Hadean Period (there are no surviving rocks).
Answer:
The correct answer is d.non-vascular plants with a dominant gametophyte.
Explanation:
Bryophytes are non-vascular plants that present a reduced and not constantly present sporophyte, also their gametophyte is very dominant and is, basically, the whole structure. Their sporophyte only grows when they're reproducing and they disappear when the spores are spread.
