In a heterozygous cross (e.g., Aa x Aa), the chances for each genotype can be determined using a Punnett square. The possible genotypes are AA, Aa, and aa. The probabilities are 25% for AA, 50% for Aa, and 25% for aa. Thus, the phenotypic ratio would typically be 3:1 if A is dominant over a.

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 flower color is determined using incomplete dominance where red is dominant white is recessive and pink is heterozygous. What are the chances that a red flower and a pink flower will reproduce to m?

In a cross between a red flower (homozygous dominant, RR) and a pink flower (heterozygous, RW), the possible offspring genotypes would be 50% red (RR) and 50% pink (RW). Therefore, the chances of producing a red flower are 50%, while the chances of producing a pink flower are also 50%. There would be no chance of producing a white flower in this scenario.


What are the chances that two parents who are heterozygous dominant for two?

If both parents are heterozygous dominant for two traits (e.g., AaBb), the chances of their offspring exhibiting different combinations of these traits can be analyzed using a Punnett square. Each parent can produce four types of gametes (AB, Ab, aB, ab), leading to a 16-cell Punnett square. The probability of specific trait combinations can be calculated from this square, revealing that the expected phenotypic ratio for two independently assorting traits is typically 9:3:3:1 for the dominant and recessive traits. Thus, the specific chances depend on the traits in question.


In humans the allele for short fingers is dominant over that for long fingers. If a person with short fingers who had a parent with long fingers marries a person with long fingers what are the chances?

If the person with short fingers has one dominant allele for short fingers (S) and one recessive allele for long fingers (s), their genotype would be heterozygous (Ss). The person with long fingers has the genotype homozygous recessive (ss). When these two individuals have children, there is a 50% chance that the offspring will inherit the dominant allele for short fingers (Ss) and a 50% chance for long fingers (ss). Thus, there is a 50% chance of the children having short fingers and a 50% chance of having long fingers.


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%.

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 of getting Huntington's if one of your parents are heterozygous?

If one of your parents is heterozygous for Huntington's disease, you have a 50% chance of inheriting the mutated gene responsible for the condition. This is because Huntington's is an autosomal dominant disorder, meaning that only one copy of the mutated gene is needed to develop the disease. If you inherit the normal allele from the heterozygous parent, you won't develop the disease.


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 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.


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.
