Frage 14
Frage
What is the difference between genotype and phenotype?
Antworten
-
Genotype is the physical or visible characteristics; phenotype is the genetic makeup
-
Genotype is the sex cells; phenotype is the somatic cells

Another word for gametes (sex cells)
-
One homologous chromosome
-
An alternative form of a gene
Frage 16
Frage
What is the difference between heterozygous and homozygous?
Antworten
-
Homozygous means that the alleles controlling a characteristic are the same; heterozygous means they are different
-
Homozygous means the alleles controlling a characteristic are different; heterozygous means they are the same
-
Homozygous means that the chromosomes are defective; heterozygous means they are normal

Frage 18
Frage
What is Mendel's Law of Dominance?
Antworten
-
Mendel is the supreme ruler of everyone, especially geneticists
-
Gene pairs separate during meiosis and recombine randomly at fertilization

Jeans of different colors cannot be near each other in your closet
-
Gene pairs separate during meiosis and recombine randomly at fertilization
