What is probability in reference to genetics?
200

300
a picture of chromosomes that are grouped together
What is a karyotype?
300
having 2 of the same alleles for a trait like TT or tt
What is a homozygous gene?
300
allele or gene that wins over another allele, such as T
What is a dominant gene?

Geneticist

hh is a recessive trait
Lawrence does not have a hitchhiker's thumb. His genotype is hh. Is this a recessive or dominant trait?
400
Gregor Mendel
Who is the father of genetics?
400
Dominant because the dominant gene always takes over the recessive gene. The only way it would be recessive would be if the genotype read gg.
Is someone who has a genotype like Gg recessive or dominant? Explain.

Probability
Robert has brown eyes. Both of his parents have blue eyes. there was a 50% chance that he would have brown eyes. What is the likelihood that one trait will appear over another trait?

Danny wants to study heredity when he goes to college. What is the study of heredity?
500
Dd is a dominant trait.
Hannah has dimples. The genotype for dimples is Dd. Is this a dominant or recessive trait?
500
False. This is her phenotype. Her genotype for blue eyes would be the letters bb.
True or false. Tiffany has blue eyes and this is her genotype.
500
Bb is dominant
Kamani's phenotype is brown eyes and his genotype is Bb. Is this trait dominant or recessive?
