There are three basic scale structures that make up the cuticle—coronal (crown-like), spinous (petal-like), and imbricate (flattened). Combinations and variations of these types are possible.
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.
Answer:
1. Attached
2. The have a 25% possibility of the disease and a 50% possibility of having the trait.
Explanation:
1. If J and K both carry the sickle cell trait, that means they are heterozygous for the sickle cell allele (Ss) where the sickle cell allele is recessive to the normal allele. The punnet square showing the possible genotypes of their potential offspring is shown in the attachment
2. The nurse would see that the genotypes possible are SS, Ss, or ss. SS would be a normal phenotype, Ss would be sickle cell trait, like the parents, and ss would have sickle cell disease. The ratios are 1 SS: 2 Ss: 1 ss. This means there is a 25% chance the child will be totally normal, a 50% chance they will inherit sickle cell trait, and 25% chance the child will have sickle cell disease.
Answer:
you just need to add what date you did it on and stuff like that it's simple.
