Question | Answer |
The genetic makeup of a cell is called its? | Genotype |
The physical traits of an organism is called its? | Phenotype |
An example of a phenotype is a cat who is Bb. (true/false) | False |
What are the possible genotypes for someone with curly hair. (use C as your letter) | Cc, cc, CC |
An example of a phenotype is a plant with yellow flowers. (true/false) | True |
Define allele | are different versions of the same gene |
A recessive allele is an allele that is weaker and can be overpowered. (true/false) | True |
The symbol for a recessive allele is a CAPITAL letter. | False.
!Bonus!
What is the actual symbol? |
A dominant allele overpowers a recessive allele. (true/false) | True |
The symbol for a dominant allele is a CAPITAL letter | True |
How many sets does an allele come in? From which parent? | they come in sets of 2, one from mom and one from dad |
Define Homozygous Dominant *(how many allleles?) | 2 Dominant alleles |
Define heterozygous *(how many allleles?) | 1 dominant allele and 1 recessive allele |
What letter case symbolizes Homozygous Dominant? | 2 Capital letters |
What letter case symbolizes a Heterozygous gene? | 1 capital letter first followed by 1 lower case letter |
Define Homozygous recessive *(how many allleles?) | 2 recessive alleles |
What letter case symbolizes Homozygous recessive gene? | 2 lowercase letters |
Curly hair is a dominant trait and straight hair is recessive. If a homozygous recessive man and a heterozygous woman have children, determine the genotypes and phenotype ratios. | Genotype : Cc and cc 50% for each
Phenotype: 50% curly and 50% straight hair |
