Step-by-Step Analysis
In a cross between two pure-breeding plants with antagonistic, discrete traits (i.e., true-breeding for alternative forms of the same trait), the parental genotypes are homozygous dominant (AA) and homozygous recessive (aa) for that trait. Crossing them yields offspring that are all heterozygous (Aa) an......Login to view full explanationLog in for full answers

Question at position 7 The mutant alleles of the CF gene that result in cystic fibrosis are recessive to normal alleles becausethe CF mutations that cause cystic fibrosis always result in no protein being produced.CF mutations result in a protein that has normal function only if normal CFTR protein also exists in the cell.dominant alleles that cause a fatal disorder, such as cystic fibrosis, cannot be inherited.the protein produced by the normal allele in heterozygotes is sufficient for normal cellular function.Clear my selection

A man who is a dwarf with achondroplasia and normal vision marries a color-blind woman of normal height. The man's father was average height, and both the woman's parents were of average height. A) Dwarfism caused by achondroplasia is autosomal dominant, which means the gene is carried on a non-sex chromosome . B) Red-green color blindness is X-linked recessive, which means that in female offspring, [ Select ] the gene is carried on the Y chromosome the gene must have both recessive alleles to be expressed in the phenotype the gene is carried on a non-sex chromosome the recessive allele is actually dominant . C) What proportion of their sons would be color blind and of normal height? [ Select ] none all half one out of four . D) What proportion of their daughters would be color blind and of normal height? none .
