Match the pattern of inheritance to the appropriate term.
A. Heterozygotes with different alleles of the DTL1 gene survive better than homozygotes B. The disease is usually passed from a mother to all children
C. Pure-breeding pumpkin plants grown on sandy soil have bigger seeds than plants of the same pure-breeding lineage grown on peaty soil.
D. A cross between a true-breeding plant with serrated leaf edges and a true- breeding plant with smooth leaf edges produces an F1 generation with 88% plants with serrated leaves.
E. A cross between two heterozygotes, DdFf, produces offspring in three phenotypic groups; Long wings in offspring with genotype D_F_, short wings in offspring with D_ff, and no wings in offspring with the genotypes ddF_ and ddff.
F. Individuals homozygous for a mutation in SME have a heightened sense of smell and large earlobes.
G. Grey chickens bred together have offspring that are black, grey and white in a 1:2:1 ratio

They may also havethe habit of washing all, or some of their food, or do not wash their food at all. a) assign genotypes to the phenotypes mentioned (see attached table) b. What mode of inheritance would most likely be exhibited by these traits if crosses were made? c.
