Document Summary
A monohybrid cross is when each parental homozygote produces one kind of gamete. (dd x dd dd). This produces a 3:1 phenotype and a 1:2:1 genotype. A dihybrid is an individual that is heterozygous at two genes (ggww) A dihybrid cross is when each parental heterozygote produces four different. Gametes are mature male or female"s reproductive cells kinds of gametes. Phenotype is 9:3:3:1 (cid:523)this is mendel"s self-fertilization of. Pedigree assumptions if it is a rare disease, always assume the dominant. Recessive mutations often involve loss of gene function. Null/amorphic alleles a non-functional protein is produced. Hypomorphic alleles a poorly functioning protein, or there are reduced. An autosomal dominant trait the normal individual is actually recessive. Dominant mutations often involve gain/change of gene function. Dominant hypermorphic alleles negative phenotypic consequences due to. Neomorphic alleles negative phenotypic consequences due to the presence (note dominance). Incomplete dominance (semi-dominance/partial dominance) think about snap dragons red snapdragon (ww) x white snap dragon (ww) produces.
