Demand is the amount of a product customers are prepared to buy at different prices. Supply is the amount of a product businesses are prepared to sell at different prices. There are many different types of market. The goods market is where everyday products such as DVDs are traded.

1.
G - dominant trait (golden)
g - recessive trait (white)
Heterozygous - Gg
White (homozygous recessive) - gg
P: Gg x gg
(picture 1)
Genotype: 50% Gg 50% gg
Phenotype: 50% golden 50% white
2.
R - dominant (red)
r - recessive (yellow)
RR - red
rr - yellow
Rr - orange
P: rr x Rr
(picture 2)
Genotype: 50% Rr 50% rr
Phenotype: 50% orange 50% yellow
sister chromatids are introduced during the (S) or synthesis phase of cell division. The two sister chromatids are separated from each other into two different cells... O <--> O
during mitosis or during the second division of meiosis.
So no, they are apart of a phase, but aren't the entirety of cell division.
Answer:
d. pxp +2pq
Explanation:
The formula for genotype frequency for a population in Hardy-Weinburg equilibrium is as under:
p² + 2pq + q² = 1
where, p = dominant allele
q = recessive allele
Here,
p² represents frequency of homozygous dominant genotype
2pq represents frequency of heterozygous genotype
q² represents frequency of homozygous recessive genotype
Also, although the genotypes p² & 2pq are different from each other yet phenotypically they both will collectively produce dominant trait i.e. free ear lobes not attached earlobes. So the term "p² + 2pq or pxp + 2pq" represents the frequency of the individuals who show the dominant phenotype in this particular population. Dominant phenotype will comprise 75% of the population.
