Question or Term | Answer or Definition |
---|---|
Features or characteristics inherited from one's parents is known as | Genetics |
The discovery that traits are inherited from parents is whose biggest contribution? | Gregor Mendel, Genetic biologist |
genotype is | the record of genes found in a living organism |
phenotype is | observed genotype, whether physical or behavioral |
Variations in the phenotype of a particular gene are known as | Alleles |
The genetic law of segregation says that | During the formation of gametes, the pairs of chromosomes separate with each gamete receiving one or the other member of he pair. |
In meiosis, one chromosome from each parent primordial sex cell will go to each resulting gamete is known as | The law of segregation. |
The 2nd law discovered by Mendel that states that traits get distributed independently from other is known as | the Law of Independent Assortment |
When looking at the genotype of the offspring, created through sexual reproduction, one from the male parent and one from the female parent, you will find | Two Alleles |
With 2 alleles present, only one is expressed and the expressed allele is known as the | dominant allele |
An allele that is present, but not expressed is known as | recessive allele |
When writing letters representing alleles for an individual, what differentiates or how is the dominant allele separated from the recessive | Dominant allele is written using Upper case letters, while recessive allele is written using lower case letters. |
Genotype: HH (trait inherited from both parents) would be described as | Homozygous dominant |
Genotype: hh (trait inherited from both parents) would be described as | Homozygous recessive |
Genotype: Hh (trait inherited from each parent) would be described as | Heterozygous |
Suppose hair color is indicated by H, knowing black is dominant and red is recessive, what hair color would these individuals have? Hh:____________ HH:_____________ hh:______________ | Black, black, red |
So what possible genotypes would a person with black hair have? | HH or Hh |
What are the possibilities for the genotypes for his gametes with a genotype: HH ? | 100% H |
When visible traits have been found linked to the sex of the individual is a phenomenon known as | Sex-linked or sex-linkage |
What is GMO abbreviated for | Genetically Modified Organism |
When a phenotype of an individual appears to be the result of sharing 2 dominant alleles is known as | codominance or incomplete dominance |
Everyone carries a pair of sex chromosomes; male (sperm) genotype is | XY |
Everyone carries a pair of sex chromosomes; female (ova) genotype is | XX |
