Question

Which sentence properly uses the word genotype?
A, Each of the homologous chromosomes in the pair had the same recessive genotype.
B, Having inherited one dominant and one recessive gene for height, the genotype of the plant was heterozygous.
C, Each gamete had the same genotype on each chromosome, so the result was identical twins.
D, The genotype was not a mutation because mRNA successfully copied the DNA strand.

Answer 1

The answer would be B, because the genotype of an organism is the pair of genes that code for a trait while the phenotype is the way that genotype is physically expressed. Hope this helps!

Answer 2

I agree with B being the answer, the genotype is the set of alleles that represents what your phenotype could be. When the genotype has one dominant and one recessive it is considered heterozygous. If the genotype has two dominant alleles or two recessive alleles then it is homozygous
