Explanation / Answer
Answer 12: 1/2 (As explained below)
There is always a 50-50 chance of having a boy or a girl. So, the answer is 1 in 2 or 1/2.
Answer 13: Homozygous (As explained below)
Zygosity is degree of similarity of alleles. When they are identical, they are called homozygous menaing similar zygosity.
Answer 14: genotype (As explained below)
Genetic makeup is rferred to as genotype, as opposed to physical appearance being referred to as phenotype.
Answer 15: 100% (As explained below)
The daughter is heterozygous for dwarfism because it's autosomal dominant.
Answer 16: Crossing over and independent assortment (As explained below)
Mendel proved recombination in peas was the result of independent assortment and crossing ovr of genes.
