In dogs, the brown fur allele (B) is dominant to the white fur allele (b), and on a different chromosome, the curly fur allele (Q) is dominant to the straight fur allele (q). Quilty has brown and curly fur (BbQq) and she mates with Razor, who has brown and straight fur (Bbqq). Part 1 Fill in the missing parts of the Punnett square for this cross. Razor's gametes are shown on the left, and Quilty's are shown along the top. Bq BQ BBqq Bbqq Brown, curly + bQ Bbqq BbQq BBQq Bq bq bbQq bbqq Part 2 Fill in the phenotypic ratios of the F1 generation from the cross between Quilty (BbQq) and Razor (Bbqq).

In humans, the genes for coloblindedness and hemophilia re both located on the X chromosome with no corresponding gene in the Y. These are both recessive alleles.  a. If a man and a woman, both with normal vision, marry and have a colorblind son, draw the Punnet square that illustrates this. b. If the man dies and the woman remarries to a colorblind man, draw a Punnet Square showing the type of children could be expected from hre second marriage. How many/what percentages of each could ne expected

In roses, purple flower color is determined by the dominant P allele, while pphomozygotes are white. The presence of long stems is determined by the dominant S allele, while ss homozygotes have short stems. Both mutations are completely penetrant.  A test cross was performed between a rose plant of unknown genotype with a white flowered, short stemmed rose plant (pp ss) and the following 200 progeny plants were obtained:   84 white flowers, long stems    16 purple flowers, long stems                  82 purple flowers, short stems              18 white flowers, short stems             Select two statements below that are TRUE. options:   The P and S genes independently assort during meiosis.     The map distance between P and S is 17 cM.   The genotype of the progeny plants with purple flowers and short stems is PP ss.   The map distance between P and S is 83 cM.   The homologs in the plant with…

Design a scheme for each possible outcome of the cross in figure and label the parental and and recombinant progeny.

Male cats are either black (B) or orange (O). Females are black, orange, or calico, which has patches of black and orange. Calico is formed from the codominance between the two alleles in the heterozygote, so a calico cat is (XB XO).  Give the genotype and phenotype ratio of a cross between an orange male cat and a calico cat.

Pure-breeding parental strains of corn with the purple, smooth and yellow, wrinkled phenotypes were crossed to produce an F1 generation, which were then crossed to produce the F2 generation. Complete the diagram showing the results of the cross below. (I included an enlarged picture of the corn as well)
