I think it's true. It might be wrong but if you want you can put false.
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.

I can't really explain it but I am pretty sure that is the right answer. Hope it helps :)
Answer:
The word ‘comet’ comes from the Greek komhth comètè (long-haired), from which we also get the word ‘comb’. Loosely, a comet appears as a hairy star. For millennia comets have been associated with disasters. Two examples are the apparitions of Halley’s Comet during the Battle of Hastings in 1066 and the destruction of Jerusalem in AD 70. Comets really do appear mysterious. While the stars, the Sun, the Moon, and the five naked eye planets all follow regular and predictable motions, comets appear suddenly, quickly move in an erratic fashion, and then abruptly disappear, apparently never to be seen again.
Comets contain dust, ice, carbon dioxide, ammonia, methane and more. Astronomers think comets are leftovers from the material that initially formed the solar system about 4.6 billion years ago.
