Question

10 multiple choice 10 points what are the components of a nucleotide? sugar, protein and lipid sugar, phosphate, and a nitrogenous base sugar, phosphate, lipid sugar, protein, and a nitrogenous base 11 multiple choice 10 points a farmer raises black and white chickens. to his surprise, when the first generation of eggs hatch all the chickens are black with white speckles throughout their feathers. what should the farmer expect when the eggs laid after interbreeding the speckled chickens hatch? 75% of the offspring will be black and 25% will be white 100% of the offspring will be black 50% of the offspring will be speckled, 25% will be black, and 25% will be white 100% of the offspring will be white 12 multiple choice 10 points traits that are inherited unchanged in a hybridization and which mask recessive traits are ______ traits. incompletely recessive codominant recessive dominant

Explanation:

1. A nucleotide is composed of a sugar (ribose or deoxy - ribose), a phosphate group, and a nitrogenous base. Proteins and lipids are not part of the nucleotide structure.
2. The speckled trait is likely due to codominance. When speckled chickens (heterozygous for the black - white trait) are interbred, using a Punnett - square analysis for a simple codominant trait, we expect 50% of the offspring to be speckled, 25% to be black, and 25% to be white.
3. Traits that are inherited unchanged in a hybridization and mask recessive traits are dominant traits. Incomplete dominance shows an intermediate phenotype, codominance shows both traits equally, and recessive traits are masked by dominant ones.

Answer:

1. Sugar, phosphate, and a nitrogenous base
2. 50% of the offspring will be speckled, 25% will be black, and 25% will be white
3. dominant
