Primary producers are the original source of food in the vent ecosystem, using chemical energy to create organic molecules. All other life depends on primary producers, and they have the greatest biomass in the community.
Primary consumers get their energy directly from the primary producers by eating or living symbiotically with them.
First order carnivores prey on the primary consumers and in turn are eaten by other animals.
Top order carnivores eat other consumers and carnivores but are rarely hunted by other creatures. Because they are separated from the primary food production by several layers, top order carnivores have the smallest biomass in the food web.
The dominant trait is hornless.
If this is correct, then the original bull is a heterozygote:
H = hornless
h = horned
Bull is Hh
Cross 1: Hh x hh (horned female) - offspring is hh (horned)
Cross 2: Hh x Hh (hornless female) - offspring is hh (horned)
Cross 3: Hh x hh (horned female) - offspring is Hh (hornless)
Cross 3 is the key to confirming this because the only way to get a hornless offspring would be if hornless is recessive.
Answer:
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
