What is the genotype and phenotype for an organism that is:
heterozygous
homosygous dominant
homosygous recessive
heterozygous
homosygous dominant
homosygous recessive
-
For example:
If
T = tall
t=short
Phenotype really depends on the key( above)
( Genotype is the three sentence below)
Homozygous dominant= TT ( Both letters is capitalize) phenotype:tall
Homozygous recessive= tt ( Both letters is short)phenotype:short
heterozygous= Tt ( One letter is capitalize, the second one is short)phenotype: tall ( the big T is dominant over the small t)
genotype- genetic combination of organism ( TT, Tt, tt)
phenotype-( physical appearance of organism ( tall, short)
Example Question:
If the mother is homozygous recessive and the father is heterozygous what is the genotype and phenotype of the offspring.
Punnett Square
t t
T Tt Tt
t tt tt
Genotype: Tt, tt
Phenotype: Tall , short
Ratio ( 2:2)
Percent: 50% tall and 50% percent short
Fraction 2/4 or 1/2
