How is the placenta adapted to perform its function/job
Natalija [7]
<span>What a fascinating question! Just out of college, on my first job, I was called to the delivery room to assist the obstetrician in collecting a blood sample from the not-yet born fetus? scalp. I was nearly immobilized at the sight of the impending birth. Ever since that night, I have gotten goosebumps when witnessing a birth. It is certainly an amazing event, and pondering the entire journey from conception to birth is marvelous! Some of the material I have found is published by religious, political and anti-abotion sites. Neither Google Answers nor I endorse any of these sites. Such web pages were cited here for conception and gestation information, and not because of ideology.</span>

You want to determine whether short wings in fruit flies are the result of a dominant or recessive mutation. You cross a short-w
Natalka [10]

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).
