Answer:
1/64
Explanation:
<em>The probability of the offspring being homozygous dominant for the three alleles is 1/64.</em>
Since the three characters assort independently, the probability of the offspring being homozygous dominant for all the three traits is an independent event.
For independent events, the probability of all the events happening together is the multiplication of individual event's probability.
For a cross involving two heterozygotes, taking tall/dwarf for example:
Tt x Tt = TT, 2Tt, tt
The probability of obtaining a homozygous dominant genotype is 1/4.
Hence, the probability of the offspring being homozygous dominant for the three alleles will be:
1/4 x 1/4 x 1/4 = 1/64
The answer is; hydrophilic heads; hydrophobic tails
The hydrophilic heads of a phospholipid are composed of a phosphate and glycerol molecule. Since the phosphate has a charge, the head are able to interact with water molecules through hydrogen bonds (Remember water is a polar molecule). The hydrophobic tails are composed of hydrocarbon chains that are uncharged hence do not interact with water. When phospholipids are immersed in water, they form a bilipid layer - with the hydrophobic tails clumped up together in the center and the hydrophilic heads on the outside.
