Answer:
a dominant mutation
Explanation:
A monohybrid testcross is a cross-breeding experiment used to determine if an individual exhibiting a dominant phenotype is homo-zygous dominant or heterozygous for a particular phenotypic trait (in this case, wing length). In a monohybrid testcross, a 1:1 phenotypic ratio shows that the dominant parental phenotype was a heterozygote for a single gene that has complete dominance. Moreover, a 3:1 ratio in the F2 is expected of a cross between heterozygous F1 individuals, which means that 75% of individuals with short wings have the dominant allele that masks the expression of the long-wing trait (i.e. the recessive allele).
Answer:
Climate change
Explanation:
This is because abiotic factors are those that are not control and deal with the environment in which the ecosystem of study or topic lays.

Answer: 23 hrs 56 min
Explanation: Because the earth rotates a full rotation in 24 hrs so the star will be in the same spot just before the full rotation is done.
one can measure time by the fractional distance a star has gone in its full circle around the sky. This is best done for stars that never set, stars near the north celestial pole.
