A skin cell and a fertilized egg cell. They are both diploid cells, meaning that they have two sets of chromosomes, one set from each parent. A frog’s skin cell has gotten its genetic makeup from both its parents and a fertile days egg cell has two sets of chromosomes as well. A sperm cell and an egg cell are haploids, meaning they only have one set of chromosomes. So the answer would be A.

Answer:
B)"My children who don't have the disease still run the risk of passing it on to their children.
Explanation:
Genetic diseases can be defined as alterations in the nucleotide sequence in a part of DNA that alter the structure of a protein and consequently cause anatomical and physiological abnormalities. These diseases are relatively rare, usually affecting few individuals in the population. These diseases can be defined into two main groups: those that affect only one gene and those that affect several. When only one gene changes, we say it is a monogenetic disease; When more than one gene has been affected, we say they are multifactorial diseases, also called polygenic.
Dominant autosomal disorders are mostly monegenic and are passed from parents to children through chromosomal inheritance. Thus, as children receive chromosomes from each of their parents, and chromosomes establish a relationship of dominance and recessivity among themselves, children may even inherit a gene that codes for an autosomal dominant disorder, however, these children may not develop this disorder if this gene responsible for it is on a recessive chromosome.
