What is the genotype of a person that is homozygous non sicklier?

RR since sickle cell is a recessive so a dominant trait means a non sicklier. If they have the trait it will be Rr which is heterozygous but RR is homozygous non sicklier.

if a man were non- hemophiliac and he marries a woman whois homozygus for nan-hemophilia,give the possible genotypes of the children
What percentage of the possible types of offspring had the same phenotype as the parents?
Hey there. To answer this accurately, i would need to know the genotypes of both parents. I'll show you a trick that works them out in a flash. A phenotype is the result of a genotype, which is the result of 2 alleles. Say if both parents were HOMOZYGOUS for brown hair, with their genotype would be BB, BB. Use a trick called a punnet square to answer this; _|B |B | B|BB|BB| <-- not the best punnet square, but the top row shows the first parents B|BB|BB| genotype (BB) and the side shows the second's. (BB) The cross of this shows all the children will have brown hair, as inherited from each parent. If the Mother had HOMOZYGOUS brown hair (BB), and the father had HETEROZYGOUS brown hair (Bb) the results would be 100% Brown hair too, because the brown hair gene (B) is dominant over the non brown hair gene (b). Below; _|B |B | B|BB|BB| <--- this shows the cross gives a 50% chance to be Homozygous for brown b|Bb|Bb| hair but 50% heterozygous for brown hair, but carrying a non- brown hair gene. If we cross 2 heterozygous parents, the results are shown: _|B |b | B|BB|Bb| b|bB|bb| <----- This shows the child has a 75% chance of having brown hair (either (BB or bB, Bb) and 25% of being non-brown (bb)). This can be used in any gene cross, but you must keep in mind that one gene will be dominant and one will be recessive. I used the brown hair gene as an example here, as I don't know whether it may be dominant or recessive to other hair colours. Also, if you were after a global statistic, I wouldn't know. I hope this helps you. Fletch

Which term describes the example below- A child with no freckles has a mother who has freckles and is heterozygous and a father who has no freckles and is homozygous recessive?
We'llsay F is dominant for freckles and f is recessive for non-freckled. The father is ff The mother is Ff The child is ff. Probability of this cross producing a homozygous recessive child is 50%. There isn't a precise term for this cross.
A farmer breeds two goats that have never fainted and their first offspring faint two days its birth what must the parents genotype have been?
The parents genotype must have been half fainting half regular and the other parent had to be the same way. The parents would not have fainted because they had the non fainting gene.

What is ownership entity?
An 'entity' is legal concept to define a non-person. The distinction is necessary as this NON-PERSON can perform/do 'normal' person acts such as signing contracts, holding a bank account, owning a piece of property, etc. This NON-PERSON does not exercise free will (as a child would) but rather is steered by the interest of PERSON(s). The owner is the person(s) who are held accountable for malicious actions of the NON-PERSON, and benefit from the rewards/profit the NON-PERSON earns.
