DaniilM [7]

Let us solve first the phenotype of this problem.

Starchy grain = AA (dominant)

Sugary Corn = aa (recessive)

AA x aa = AaAa ; AaAa

<span>     A    A</span>

<span>a  Aa   Aa</span>

<span>a  Aa   Aa</span>

The result of the cross is that the progeny will become heterozygous.

<span>If there is 58 progeny sugary, there will also be 58 starchy. It is 50%.</span>

Choose a symbiotic relationship from the list below. Research the relationship and write a 300 word report that includes the ben
ser-zykov [4K]

Symbiotic Relationships : A long term relationship between two biotic factors, where at least one benefits





Mutualism= symbiotic relationship where both organisms benefit (+,+) o Example- rhino & woodpecker (rhino gets rid of parasites and bird gets food) 



Parasitism = symbiotic relationship where one benefits and the other is harmed, but not typically to the point of death (+,-) o Example- tapeworm in an animal, tick or flea on a dog (parasite benefits at the expense of the host) 




Commensalism = symbiotic relationship where one benefits and the other is neither helped nor harmed (+, 0) o Example- barnacles on a scallop (barnacles get a habitat/place to attach while the scallop is not hurt or helped by their presence).



















Symbiotic Relationships:

In symbiosis, two or more species live together in a close, long term association. Symbiotic relationships can be beneficial to both organisms or may benefit one organism and leave the other harmed or unaffected. Parasitism is one type of symbiotic relationship that is detrimental to, or harms, the host organism. In this relationship, one organism feeds on and usually lives in another, typically larger, organism. Mutualism is a symbiotic relationship in which both participating species benefit. A well known instance of mutualism involves ants and aphids. The ants feed on fluid the aphids secrete, and in exchange, the ants protect the aphids from insect predators. A third from of symbiosis is commensalism, a symbiotic relationship in which one species benefits and the other is neither harmed nor helped. Among the best-known examples of commensalism are the feeding and protection relationships between certain small tropical fishes and sea anemones, marine animals that have stinging tentacles.








Hope that helps!!!!!! :)
