Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three "dominant" capital letter genes (A, B and C) control dark pigmentation because more melanin is produced. The "recessive"alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.

Answer:
The yellow form can exist in both the "live yellow" and "heat-killed purple" forms.
Explanation:
To carry out these transformation tests; for example change of purple structure form into the yellow structure; DNA, RNA, and proteins will be confined from the yellow structure and infused to heat-killed purple structure each in turn in singular examinations. At the point when DNA will be changed into heat-killed purple structure form, it is changed over and converted to the yellow structure form. In this way, the yellow structure form can be acquired from live yellow just as heat-killed purple structure (changed with DNA or changing guideline from the yellow structure).
Answer:

Explanation:
The formula for exponential population growth is
where
initial population of E.coli i.e 100
k is the rate of population growth i.e 2 as the population doubles
t is the time period i.e 20 minutes
Substituting the given values in above equation, we get -
Generation time
minutes
or 0.35 hours
Answer:
Explanation:
The sperm reproduction startes in the testicles.Sperm are produced in the testicles and develop to maturity while traveling from the seminiferous tubules through the epididymis into the vas deferens. As a male and female have sexual intercourse their are millions of sperms released which travel from the seminiferous tubules through the epididymis into the vas deferens as that happens the sperm enters throught the partner from here it takes its journey to the egg using ts tail to swim the first sperm to reaches the egg then uses the acrosome, which is a specialised Lysosome that releases enzymes so that the Sperm Cell can penetrate the Ovum Coat of the Egg.It breaks through and forms a baby.
