What is a phenotype?
How a gene shows up in your physical traits (Example: you have blonde hair)
What is a recessive allele?
a type of allele that won't physically show up on its own (it needs two copies to be present)
What is a dominant allele?
a type of allele that only needs one copy to physically show up on its own (Aa)
What is the difference between a gene and an allele?
An allele is a variant of a gene - example: you can inherit the allele for brown or blue eyes
What two letter (upper or lowercase) combination shows a heterozygous trait?
Gg or Aa (Hetero- means "different" or "opposite"
What is a gene?
A piece of a chromosome that holds information about you
What is a genotype?
What your genes/ alleles actually show (Aa, bb, BB)
Which flower has dominant alleles?
Red
What did GREGOR MENDEL cross in his second experiment?
First Generation PURPLE PEA FLOWERS (they were not true breeders)
Name a dominant trait in pea plants
Round seed, purple flower color, yellow seed color, inflated pod shape
A gene is a segment/sequence in your DNA (True or False?)
True
What did GREGOR MENDEL cross FIRST? Be specific :*)
True breeders; purple X white pea flowers
What is an offspring's PHENOTYPE?
The appearance of the genes or what the genes will LOOK like.
What is the definition of inheritance in biology?
the process of passing genes from parent to offspring
Name a recessive trait in humans
blonde hair, blue eyes, freckles, attached ear-lobe, etc.
If a flower shows codominance, what does that mean?
Two dominant alleles are physically shown/expressed
What % chance do the offspring of these two parents have of inheriting a genetic condition? (Mutated gene)
50%
