The colors of chicken feathers follow a codominant pattern. Both Black (B) and White (W) feathers are dominant phenotypes while checkered (BW) is the heterozygous phenotype.  Show a cross between 2 checkered chickens. 1. P1:  2. Punnett Square: 3. Genotype symbols: 4. Genotype in words: 5. Genotypic ratio:

Match the type of genetic dominance with the appropriate term: More than two type of alleles for a given trait Both alleles are expressed equally 1. Complete dominance 2. Incomplete dominance Phenotype of dominant homozygote and heterozygote are same 3. Codominance 4. Multiple Alleles Heterozygotes have intermediate (hybrid) between the two homozygotes

ABO blood group is co-dominant for AB and O is recessive. Rh (+/-) factor is completely dominant. A man with O/positive blood and a woman with A/negative blood have six children. All of their children have A + blood type. What can you conclude about the parents’ genotypes? Group of answer choices Both mother and father are likely homozygous  at both loci Mother was homozygous at the ABO locus but heterozygous at the Rh factor locus Father was homozygous at the ABO locus but heterozygous at the Rh factor locus Mother was heterozygous at both loci

Assumptions: . If the parent expresses the trait, they are homozygous dominant If the child/children express the trait but the parents do not, the parents are heterozygous. Traits selected: Brown Hair/Eyes And Widows Peak Write the Letters you will be using n the Punnet square for each trait: _Ww Bb_and_ww Bb_ Father Genotype: WW Bb Mother Genotype: ww Bb Parent Gametes possible gametes: possible gametes: Do you have the phenotype of either of the traits in the cross? If you do, which one? Are there any other offspring with either trait? Which trait? Which phenotypic probability did you fall into? Which phenotypic probability did other offspring fall into? I
