Chapter 9 Mastering Biology picture questions

a. GG b. Green c. Gg d. green e. Gg f. green g. gg h. yellow

Drag the genotypes and phenotypes from the left to correctly complete the Punnett square for the F2 generation. Drag only blue labels to blue targets and pink labels to pink targets. Labels may be used more than once.

a. Dd b. DD or Dd c. dd d. DD or Dd e. DD or Dd f. dd

Drag the labels to the pedigree to identify the genotypes of individual family members. If you can't tell with certainty whether an individual is homozygous dominant or heterozygous dominant for the trait, place the label "DD or Dd" in that box.

a. homologous chromosomes b. gene locus c. recessive allele d. centromere e. sister chromatids f. alleles g. dominant allele

Drag the terms to their correct locations on the figure below.

BBGg All of the offspring have black eyes, and there is a 3:1 ratio of skin color.

In the following cross the genotype of the female parent is BbGg. What is the genotype of the male parent? [Hint: B = black eyes, b = orange eyes, G = green skin, g = white skin]

three There are three loci, or specific locations, for genes on the chromosomes shown: PP, aa, and Bb.

Part complete How many loci are shown on the homologous chromosomes in the figure below?

Mendel's laws of segregation and independent assortment.

The observed distribution of alleles into gametes is an illustration of _____.

bbgg This result of the cross indicates that both orange eyes and white skin are recessive.

What is the genotype of the parent with orange eyes and white skin? (Note: orange eyes are recessive.)
