Does Natural Selection operate directly on the genotype?
Natural selection acts on the phenotype, which is influenced by the genotype. Favorable genetic traits increase an organism's chances of survival and reproduction, leading to their greater representation in future generations.
If the mother is heterozygous for a trait like widows peak what are the chances that the eggs she produces will have the gene for a widows peak?
Half her eggs will have the widow's peak gene, and the other half will have the other allele, so it's 50%.
A human male can roll his tongue (genotype Rr) while his female partner cannot (genotype rr). What are the chances of any children they may have being able to roll their tongues?
The ability to roll one's tongue is a trait influenced by a dominant allele (R) and a recessive allele (r). The male with genotype Rr can pass on either the R or r allele, while the female with genotype rr can only pass on the r allele. Therefore, their children could inherit either Rr (able to roll their tongue) or rr (unable to roll their tongue), resulting in a 50% chance of having the ability to roll their tongues.
Which is the dominant gene father has dark brown eyes mother has blue eyes?
Sure you don't mean heterozygous dominant? If you don't there would be no blue eyed offspring. Let's assume you meant heterozygous dominant.B = brownbl = blueBbl X Bbl1/4 of the offspring would have blue eyes, 25%.
What are the chances of being sterile?
The chances of being sterile vary depending on the underlying cause. Some common factors that can lead to sterility include age, genetics, infections, hormone imbalances, and lifestyle choices. It's important to consult with a healthcare provider for a personalized assessment if you have concerns about fertility.
Both a man and a woman are heterozygous for freckles Freckles F are dominant over no freckles f What is the chances that their child will have freckles?
PHENOTYPE: 75% with freckles 25% without freckles GENOTYPE: 1FF:2Ff:1ff
What are the chances of a woman with blood type b and a man with blood type ab having a child with type 0?
There is no chance that this baby would have the blood type O. In order for someone to have the blood type O, the genotype must be IoIo. That means that each parent would have to have an O allele in their genotype. In this case only the mother has the possibility of having an O allele. Genotypes of blood type A: IbIb, IbIo Genotype of blood type AB: IaIb Genotype of blood type O: IoIo here is a punit square to show you heterozygous mommy heterozygous daddy IbIo IaIb Ib Io Ib IbIb IbIo Ia IaIb IbIo This child would have 75% chance of having the blood type B and 25% chance of being type AB
What is an individual with genotype AAA described as?
An Aa genotype can result in the same phenotype as either an AA or AA genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.
How tall will i be at 18 if i am 5'9 at 15 my mum is 5'6 and my dad is 5'8?
chances are that you may be taller, but genetics are a lottery, and also you have external factors that develop the phenotype, eg. i smoked during my teens, I'm now 5' 7'' :( phenotype is what effect the world has on the genotype, pretty much

What are the chances of an ac gyenotype and an as gyenotype having ss or sc children?
The chances of an AC genotype and an AS genotype having children with an SS or SC genotype depend on the inheritance patterns of sickle cell traits. The AC parent can pass on either the A or C allele, while the AS parent can pass on either the A or S allele. The possible combinations for their children are AA, AC, AS, and CS, meaning that neither SS nor SC offspring can occur from these parents. Thus, the chances of having SS or SC children are zero.
What are the chances of having kids that can roll their tongue if a heterozygous tongue roller has kids with someone who cannot roll?
If one parent is heterozygous for the tongue rolling gene (Tt) and the other parent cannot roll their tongue (tt), the chances of their children being tongue rollers (Tt) is 50%. The other 50% chance is that the children will not be able to roll their tongue (tt).
What are the chances of an orange cat being female?
The chances of an orange cat being female are about 20-25, as orange cats are more commonly male due to genetics.
What are the chances that a female will grow to be taller than her father?
If her mother is tall, there is a chance she will take after her genetics as opposed to her father's.
Why do children have characteristics of both their mother and father?
Children have similar characteristic's to their parents because when they are conceived, both of the parents genes unify to create a new set of characteristic'd depending on dominant and recessive traits. For example, Jane and Henry find out they are having a baby. Jane has homozygous blue eyes whilst Henry has heterozygous brown eyes. The chances are that their baby will either have 50% homozygous blue eyes or 50% heterozygous brown eyes.
What chances does an offspring have of getting Gaucher Disease?
It depends on whether your parents are carriers or not. If they are NN (or normal normal) and they have sex with someone who is Nn (or normal gauchers) than using a punnet square the chances of them becoming a carrier are 50 50. If your parents are both carriers ie. Nn Nn then the chances of them becoming a carrier are 50% and them having the disease is 25%. If your parents are nn Nn then the chances of them becoming a carrier is 50% and the chances of them having the disease is 50% so they will either be a carrier or have the disease either way. If your parents are nn NN then there is a 100% chance of them being a carrier. You can figure this out by looking at your family tree and seeing who had the disease before you in your family. This is only very basic Mendelian genetics so i would consult a doctor for a more legitimate answer.
Chances of illness?
Every individual's chances for breast cancer are different. Diet, exercise, and genetics all play a role in the chances for getting breast cancer. On average, every woman born has a one in eight chance of getting breast cancer.
