The allele combinations observed in individuals are determined by the genetic variations they inherit from their parents. The ratio of allele combinations in a population would depend on the frequencies of different alleles present in that population and the patterns of inheritance of those alleles. These ratios can vary depending on the specific genetic traits being studied.

What is the phenotypic ratio of the offspring when a tall man marries a short woman?
The phenotypic ratio of the offspring when a tall man marries a short woman is 3:1 (tall/short). The phenotypic ratio is figured by using the punnet square with the dominant allele for tall and the recessive allele for the short gene.
What is an organisms genetic makeup or allele combination?
Genotype
What information would tell you if a cross showed complete dominance?
If a cross between two organisms shows complete dominance, all individuals in the first generation (F1) will display the dominant trait. This indicates that the dominant allele is fully expressed, masking the recessive allele. To confirm complete dominance, further crosses involving the F1 generation can be conducted to observe the phenotypic ratio of the offspring.
What is the ratios for a heterorozygous female and a homozygous dominant male?
The offspring will inherit one dominant allele from the homozygous dominant male and have a 50% chance of inheriting the dominant allele from the heterozygous female. Therefore, the ratio of offspring with the dominant allele to those without will be 1:1.
What is the allele combination of an individual?
An allele combination refers to the specific alleles that an individual has for a particular gene. For example, a person may have two alleles for eye color, one from each parent, which could be a combination like "brown-blue" or "brown-brown". Allele combinations determine an individual's unique genetic makeup for a given trait or gene.
What Percentage Of The Offspring Will Be Expected To Have The TTYy Allele Combination?
50% of the offspring are expected to have the TTYy allele combination. This is because the TY and Ty alleles segregate independently during meiosis, resulting in a 1:1 ratio of TY:Ty alleles in the gametes that combine during fertilization.
How do you show a heterzygous allele combination?
A heterozygous allele combination is typically shown using letters to represent the alleles of a gene. For example, if the alleles for a gene are "A" and "a," a heterozygous individual would be represented as "Aa." This signifies that the individual has one copy of each allele.

How many Africans are carriers of the sickle cell allele?
A very high ratio of 1 in 11.
If both parents were Dd then what would the phenotypic ratio be?
If both parents were Dd, they would both be heterozygous for a particular trait. The phenotypic ratio of their offspring would likely be 1 dominant : 2 heterozygous : 1 recessive. This is because the dominant allele masks the recessive allele, resulting in a 3:1 ratio.
How many African Americans are carriers of sickle-cell allele?
A very high ratio of 1 in 11.
How many African Americans are carriers of sickle-cells allele?
A very high ratio of 1 in 11.
What is the trait being studied in the heterozygote?
The trait being studied in the heterozygote is typically the dominant trait, as it is the one that is expressed in the presence of at least one dominant allele. This allows researchers to observe how the dominant allele interacts with the recessive allele in terms of phenotype expression.
What are the allele combinations from a genotype of F f D d in a Punnett Square?
The allele combination,or gene pair,can be BB,Bb,bb
What is the ratios for a heterorozygous female and a homozygous dominant male?
The offspring will inherit one dominant allele from the homozygous dominant male and have a 50% chance of inheriting the dominant allele from the heterozygous female. Therefore, the ratio of offspring with the dominant allele to those without will be 1:1.
