Additional information is missing. It is as follows: In fruit flies, the allele for red eyes is dominant over the allele for pink eyes. Straight wings are dominant over curled wings.
Answer:
Genotype = RrSS and RrSs in 1:1 ratio so each has 0.5 probability
Phenotype = All red eyed and straight winged
Explanation:
Given,
Red eyes (R) is dominant over pink eyes (r)
Straight wings (S) is dominant over curled wings (s)
Fly 1 : Homozygous red eyed, curly winged = RRss
Fly 2 : Pink eyed, heterozygous straight winged = rrSs
RRss will produce Rs gametes and rrSs will produce rS and rs gamates.
When fly 1 and fly 2 mate : RRss X rrSs :
rS rs
RS RrSS RrSs
The genotypic ratio is 1 : 1 ( RrSS : RrSs ) that means that each genotype has 0.5 probability. Both the genotypes though have at least one dominant allele for each gene so the entire progeny will have red eyes and straight wings.
Answer:
B
Explanation:
Offspring would all have genes of TT, TT, Tt and Tt. All offspring have the dominant tall gene.
Answer:
It wouldn't be able to pump oxygen to your body
Explanation:
One side goes to the lungs to collect oxygen and the other side pumps the oxygen to your body. If there was no chamber the blood would not be able to flow to its proper area and you would die
Answer:
yes
Explanation:
In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol.
Answer:
They are all organelles in a cell
