Which of the following is false?
a. the pollen grain shape was studied by Mendel.
b. Mendel believed that the characteristics of pea plants were determined by the inheritance units or factors from both parents.
c. An allele is one of several possible forms of a gene.
d. When the genotype consists of a dominant and recessive allele, the phenotype will be like the dominant allele.
In a trait that follows Mendelian rules of inheritance, what is the only way an organism can have the recessive phenotype?
A. By having the homozygous recessive genotype
B. By being heterozygous for that genotype
C. It is not possible to get the recessive phenotype in Mendelian genetics
D. If one parent is homozygous recessive for that trait, any offspring are guaranteed the recessive phenotype
E. By being homozygous dominant for that genotype
What is Mendelian inheritance?
a. Mendelian genes code an entire phenotype so that children will not be clones of their parents.
b. Mendelian genetics are those genes that code for dominant or recessive illnesses but only if no polygenic traits cancel them out.
c. Mendelian genes sit at one loci with one allele from Mom and one allele from Dad.
d. Mendelian genetics is when two or more genes at two or more loci express one trait
