Mendel's results can be explained through the principles of probability by considering the inheritance of alleles during gamete formation and fertilization. Each gamete carries one allele for each trait, and the combination of alleles from each parent follows a predictable ratio, as outlined in Mendel's laws of segregation and independent assortment. For example, in a monohybrid cross, the 3:1 phenotypic ratio observed in the offspring can be understood through the probabilistic outcomes of allele combinations. Thus, probability provides a framework for predicting the likelihood of different traits appearing in future generations based on Mendel's observations of pea plants.
The probability of having a blue-eyed child depends on the genetic makeup of the parents. If both parents carry the recessive allele for blue eyes (Bb), where "B" represents the brown eye allele and "b" represents the blue eye allele, there is a 25% chance of having a blue-eyed child (bb). If one or both parents have brown eyes but carry the blue eye allele, the probability may vary. If neither parent has the blue eye allele, the probability of having a blue-eyed child is 0%.
The child will have the disorder, only if the recessive allele from both the parents is transferred to the child. Therefore, the probability is 1/4.
If the mother has one LL allele for color lameness, it means she can only pass on the L allele to her offspring. Since she has one allele for normal vision, that allele does not affect the color trait directly. Therefore, the probability that her child will inherit the LL genotype for color lameness is 100%, as the mother can only provide the L allele.

The step that explains the probability that a particular allele will be in a gamete is the Law of Independent Assortment during meiosis I. This law states that alleles of different genes segregate independently of one another during the formation of gametes, leading to various combinations of alleles in the resulting gametes.
If the dominant allele for pea shape is more prevalent in the population, then the probability of a gamete receiving a dominant allele for pea shape will be higher. The frequency of the dominant allele in the gene pool directly affects the likelihood of it being passed on to offspring through gametes during reproduction.

The probability that the mother produces a gamete with the allele for dimples is 50%. This is because each parent only passes on one of their two alleles for a given trait to their offspring, and in this case, the mother has a 50% chance of passing on the allele for dimples.

Oh, isn't that a happy little question! The probability of producing a gamete with the allele for attached earlobes depends on the individual's genetic makeup. If the individual is heterozygous for the trait (Aa), the probability would be 50%. If they are homozygous dominant (AA), the probability would be 0%, and if they are homozygous recessive (aa), the probability would be 100%. Just like painting, genetics can be a beautiful and fascinating landscape to explore.

Normal gametes should contain one allele from each gene.
A homozygous recessive individual (ss) carries two copies of the recessive allele and does not possess a dominant allele. Therefore, when this individual produces gametes, all gametes will carry only the recessive allele (s). Consequently, the probability of a homozygous recessive individual producing a gamete with a dominant allele is 0%.
A gamete containing a BB genotype will carry one B allele from each parent. This gamete will contribute one B allele to offspring during fertilization.
