Once again weâre looking at flying out to see friends over a weekend this spring. And once again it looks like the lowest cost option is Spirit Airlines. Now if youâre flying by yourself and flying Spirit Air would only save you $50 or so I can completely understand why you may choose to go with another airline. In our case, we are flying with our family of four.
A recessive trait is the phenotype that is seen only when a homozygous recessive genotype for the trait of interest is present. This means that an individual must have two recessive alleles for the gene that determines this trait of interest.
There are different forms of the same trait. In this next video notice the different shapes of the noses. These would be examples of alleles because they are different forms of the same trait Traits can also be dominant or recessive Each individual has two alleles for each gene, one coming from each female and the other from the male. With dominant traits, an individual carries either two dominant genes or one dominant and one recessive gene. A dominant gene can be expressed even if only one copy of the gene is present. A recessive trait will only be expressed if an individual has two recessive alleles. In this example purple color is dominant over white color
