Punnet squares show all possible allele combinations resulting from a genetic cross
Genotype
During the formation of gametes in a hybrid tall plant, the alleles for tall and short height do not stay together. They segregate and assort independently during meiosis, resulting in a random combination of alleles in the gametes. This allows for a variety of possible genetic combinations in the offspring.
an organism's genetic makeup, or allele
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.
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.

A Punnett square shows all of the possible outcomes of a genetic cross. It is a grid that illustrates the combinations of alleles from each parent, allowing for the prediction of offspring genotypes and phenotypes. By filling in the squares with the potential allele combinations, one can visualize the likelihood of each outcome resulting from the cross.
Being homozygous for the "b" allele means that an individual has two identical copies of the "b" allele at a specific gene locus. This implies that both alleles are the same, resulting in a specific genetic trait or characteristic associated with the "b" allele being expressed.
NO
Recessive allele exhibits its trait only when paired with another recessive allele in a genetic cross.

An allele is a specific version of a gene, while a genotype refers to the combination of alleles that an individual has for a particular trait. In simpler terms, an allele is like a variation of a gene, and a genotype is the specific genetic makeup of an individual.
Random changes in allele frequency are due to genetic drift.
The allele combination of an organism is significant because it determines the genetic traits and characteristics that the organism will have. Alleles are different forms of a gene that can influence traits like eye color or height. The specific combination of alleles that an organism inherits from its parents will determine its physical appearance and other characteristics.
