14 Jan 2013 Which form of reproduction is most likely to give a population of organisms genetic variety? Why? Vocabulary Allele Segregation Activity

Male alleles are both brown. Female alleles are brown and white. Show the possible outcomes for the offspring.
I can differentiate and make connections between phenotypes and genotypes of organisms.
The instructions for a specific inherited trait that are found on one section of a chromosome of DNA. For example, you have a gene(s) for each of the following traits: Hair color Eye color Hitchhiker’s thumb Tongue rolling Hairline Earlobes
The different forms of a gene. Each gene is made up of at least two alleles, one inherited from the male parent and one from the female parent. For example: Gene for hair color: Blonde hair OR Black hair Gene for eye color: Blue eyes OR Brown eyes Gene for thumb shape: Hitchhiker’s thumb OR Straight thumb Gene for tongue rolling ability: Can roll tongue OR Can’t roll tongue Gene for hairline: Widow’s Peak OR Straight hairline
Alleles that cover up, hide, mask, or over-power other alleles. The trait associated with the dominant allele always shows up when it is present (it dominates!). Writing convention: UPPERCASE letters. For example: H = Dominant (Straight thumb) h = Recessive (Hitchhiker’s thumb) Hh = Straight thumb HH = Straight thumb hh = Hitchhiker’s thumb
Alleles that are covered up or hidden. The recessive trait will only show up if a dominant allele is NOT present. Writing convention: lowercase letters For example: W = Dominant (Widow’s peak) w = Recessive (Straight hairline) Ww = Widow’s peak ww = Straight hairline
Both alleles are the SAME as each other. Homo = same For example: TT = homozygous DOMINANT (both alleles are dominant) tt = homozygous RECESSVIE (both alleles are recessive)
Each allele is DIFFERENT from each other. Hetero = different For example: Hh Ss Ww Tt
The genes that an organism has in their DNA Genotype = Genes Represented by letters Examples: Hh BB tt Dd
The traits or characteristics of an organism (What it looks like) Phenotype = “Features” Examples: Brown or blonde hair color Brown or blue eye color Hitchhiker’s or straight thumb Tongue rolling ability or not Widow’s peak or straight hairline
