Answer:
Alleles for feather colour exhibit incomplete dominance or co-dominance.
50% gray offspring + 50% black offspring
Explanation:
<em>It means that the alleles for feather colour in the hen exhibit incomplete dominance or co-dominance over one another.</em>
Assuming the allele for white colour is B, white colour will be b while the heterozygote Bb gives the gray phenotype.
Gray rooster + gray hen = 15 gray chicks, 6 black chicks and 8 white chicks.
15:6:8 is roughly 2:1:1 which is phenotypic ratio obtainable from crossing two heterozygous individuals as pointed out by Mendel.
Bb x Bb = 1BB, 2Bb, and 1bb
Crossing the gray rooster (Bb) with a black hen (bb):
Bb x bb = Bb, Bb, bb, and bb
= 2Bb (gray):2bb (black)
50% of the offspring will be gray while the remaining 50% will be black.

2. Thymine
Explanation:
These are the four nitrogen bases of DNA nucleotides. It's just something that you have to memorize in order to be able to successfully study DNA. In case you are asked which base pairs with which, always remember this saying about base pairs: A and T, and, G and C.

Answer:
The forces on a thrown ball after it leaves the thrower's hand are the force of gravity and possibly the force of air resistance.
Explanation:
The force of gravity at the surface of the Earth is the gravitational acceleration at that location (9.8 meters per second per second) times the mass of the ball.
