Genetics is a fascinating world, focusing on the inheritance of traits from parents to offspring. Gregor Mendel, the father of classical genetics, made significant contributions to our understanding of this process. Dominant and recessive traits play a crucial role in determining an individual's characteristics.

- A new hypothesis is that all Homo Sapiens originally had Dark Eyes (Brown) and that one individual about 6,000 to 10,000 years ago had a mutation w...
- If everyone has the dominant allele for eye and skin color by some chance, then yes I think it is POSSIBLE (trying to stress it), but highly improb...
- You must remember that dominance of an allele and how common that allele is in the population (its frequency) are not the same thing. Most of the a...
- All of your cells have the same chromosomes, in which 23 came from your father and 23 from your mother. Just remember, only human diploid cells hav...
- If Brown is dominant and Blue is recessive: B=brown and b=blue, the chances of brown are dependent on the parental traits. If the parents had Bb an...
- It doesn't matter in a Punnett square, you can put whichever genotype you prefer first. Personally, I prefer to put the dominant allele on the top....
- You pose a good question: how could all of this variation derive from just two people? We have people with red hair and black hair, brown, and blon...
- Note: My original answer was a bit sloppy — this is an edited version. First, many genes may influence a single phenotype. Eye color is an excellen...
- So DNA goes into a baby by way of meiosis, which is where cells divide to reduce their chromosomal number to the haploid state, creating gametes, w...
- Because the gene that controls eye color has colors that are more common in the population than rarer colors.
Let's explore the kinds of inheritance patterns seen in Mendelian Genetics! Uncover the secrets of alleles, and explore the difference between homozygous and heterozygous traits. Learn about dominant and recessive traits, and how they influence genotypes and phenotypes. Finally, discover how a Punnett Square can predict gene inheritance.

- That's because Khan Academy wants to see if you understand some things already and to help you get the idea of what the subject is.
- Since the A allele is dominant, both AA and AO are considered the A blood type. The categorization of the blood types refers to the antigens (or sm...
- It's easier to look at it as both antigen A and antigen B are dominant and O is neither. B can't cancel out A and A can't cancel out B, so you can...
- When we refer to the different blood types (ie. AB, A, B, or O), we are classifying them according to the presence of a series of sugar molecules o...
- An individual can only have two alleles at most for a given gene. Multiple alleles (as in the case of A/B/O for blood type) are a phenomena for a p...
- Yes! An allele, as discussed in the video, is a form of a gene. We typically think of human genes as having two alleles: one from the father and on...
- If both parents had blood type AB, that would mean that the offspring would have: 25% chance of having the genotype AA (phenotype would be blood ty...
