Genetics Dominant Traits
Natalie White
A dominant trait or a dominant allele will show up in the offspring if one of the parents has it. A dominant allele will overpower the recessive trait and show up.
In genetics, each parent has a different genetic makeup therefore their allele may be different. The offspring of these parents will posses 1 trait from each parent. The dominant and recessive alleles decide which trait will appear in the child. FOR EXAMPLE - (hair) If 1 parent is homozygous for brown hair (dominant) and the other parent is homozygous for blonde (recessive) the child would have brown hair because it is dominate over blonde. We can tell which traits the child may have using punnett squares.
(homozygous - same alleles - ex. BB)
(heterozygous - different alleles - ex. Bb)
Dominate and Recessive Genes/Heredity were first discovered by Gregor Mendel with his pea plant experiment.
Reflection - I find genetics and DNA to be a very interesting unit and it is one of my favorites. I learned a lot about genetics from 7th grade science however I did learn more in depth about Co-dominate and incomplete dominance from this unit. '
Outside of Biology - Punnett squares and genetics can be used outside of science to determine possible outcome of what your children would look like.
