In a create a baby lab that I participated in with a fellow classmate, we would flip a coin to see if certain traits such as mouth shape, nose size, even the presence of dimples would show up on our "baby" based on the predominincy of our genes. In order to get the certain Genotype that we were sposed to be carrying to pass on to our baby, we would flip the coin twice to either get a predominint, or dominint homozygous gene, or a heterozygous gene.
Now, the best thing about this lab is that it gave me one heck of a better understanding of how genes can be passed onto the child of new parents. Well, Bikini Bottom Genetics lab helped out with recessive genes as well. But any way, when you have both parents carrying homozygous genes of a particular trait, it a pretty good chance that your going to have that trait show up on the child, whether it's a dominint, or predominint trait. But, when you have heterozygous genes being carried by just one of the parents, then things start to become a gamble. You don't know what the baby will turn out to be like. For example, if the genes are represented by letters lower and uppercase to show hetero, and homozygous genotypes, then two sets of capitals such as (DD, DD) combined will 100% show up on the baby. But when you get something like (DD, Dd), the chances reduce because of the fact that heterozygous genes (Dd) are recessive, and can be skipped a generation.
One of the biggest things that I needed to get some comprehention on was the Pheno, and geno. But, i learned that recessive genes tend to be a genotypical subject becuase of the fact that recessive genes ane hidden most of the time. Meaning that you can't see them phenotypically. When you can see them Phenotypically, then you got dominint genes that were passed on. If that didn't make sense, let my clarify. Phenotype is the genes you can see because they show up on the child, and Genotype is the genes that the baby is carrying, but doesn't show. The phenotype can be either be dominint or recessive because of the game of chance, but all genotypes are recessive based on the fact that they didn't show up on the child. But don't think the Genotypes can't become phenotypes. The genotypes lie inside the baby, waiting, lurking, for their chance in later days when the baby grows to be an adult and reproduce. The recessive genotype could turn into a, dare i say it, phenotype.
The labs brought me up to a better par on how genetcs work, i just need to get the vocab matched up and what not so i can have some what of an expert understanding. But, i do know why i look more like grampa than i do my poppa now, so i guess i got SOMETHING outta these labs.
