Genetics and Heredity

Explain what an allele is

• An allele is one of 2  versions of a gene.

• It is not an allele but a version gene

• An allele is one of 2  versions of 2 different gene.

• An allele is one of 12  versions of 2 gene.

1.  Explain the difference between genotype and phenotype.

• Phenotype is the set of genes that offspring gets for a trait   Ex. TT or Tt or tt

  Genotype is the physical characteristics of a trait “What you see”   Ex. Tall or short 

• Phenotype you can see

  Genotypes you can see

• Genotype is the set of genes that offspring gets for a trait   Ex. TT or Tt or tt

  Phenotype is the physical characteristics of a trait “What you see”   Ex. Tall or short 

  
  

• Genotype the genetic makeup of an organism. Phenotype is is the genetic makeup of an organism.

1. What other terms pair with purebred and hybrid?

• Car that takes gas and a car that uses both gas and gas

• Purebred–homozygous Hybrid–heterozygous

  
  

• Physical appearance

  Genetic makeup

  Alleles gained from one parent

• hybrid is a cross between one species of animals. A purebred animal is produced by breeding two animals of the different species, subspecies, and breed.

1. Explain the process of heredity.

• Heredity is the passing of only good traits from one generation to the next.

• There's a Gene for Every Trait You Inherit.

• Heredity is the passing of traits from one generation to the next.

The allele / (trait) that is hidden. The offspring will not have the trait represented unless there are two of these.

• recessive allele

• dominant allele

• dominant allele

• co-dominant allele

1. If someone were to have the heterozygous genotype for a trait, how would that be represented using letters?

• nN

• NN

• Nn

• I am not sure

1. Who is the scientist that is considered the father of genetics?  What did he study for his research?

• Rosalind Franklin

  involvement in cutting-edge DNA research

• Reginald Punnett was known for creating the Punnett square

• Gregor Mendel for his research using pea plants.

  
  

• Erwin Chargaff found that in DNA, the ratios of adenine (A) to thymine (T) and guanine (G) to cytosine (C) are equal.

1. Which of the following results would be accurate based on the data given?                    C     c

•  A heterozygous curly haired father is crossed with a heterozygous mother.

•  There would be a 100% chance that the offspring would have curly hair.

• There would be a 50% chance that the offspring would also be heterozygous like mother and father.

• 1. There would be a 25% chance that the offspring would have curly hair.

  
  

• I am not sure
