Which of the following best explains the difference in flower color of the African violets in the greenhouse?

An enzyme responsible for flower color does not fold correctly in cooler temperatures, and the greenhouse is warmest in the center

Which of the following represents the relative positions of these four genes in the chromosome

CABD

If the blue-eyed sheep are mated with each other, what percent of their offspring will most likely have brown eyes?

25%

The probability that Matthew and jane's first child will be an achondroplastic dwarf is

50%

In cross II, the genotype of the dark, short-haired parent is

CcBb

Pedigree question: the expression of this trait is most likely due to which of the following?

Autosomal recessive inheritance

Mary-flower question: which of the following statements best explains the data

Flower color is an inherited trait, and the F1 and F2 phenotypes of the flowers arising from the pink and white cross can bear be explained by another gene product...

Based on the data in Table 1, which of the following best explains why there are no individuals with constricted pods in F1?

Inflated pod shape is dominant to constricted pod shape

Which of the following directly describes the relationship of the dark-coat-color allele in the albino condition?

It is dominant

Pedigree question answer

P GEN: TWO UNAFFECTED F1: TWO AFFECTED

Which of the following represents a cross between a white-eyed female and a red-eyed male?

Rr x Rr

The data above represents the results of three different crosses w blue of white gene. Which of the following best explains the mechanism of inheritance of the gene?

The allele for blue is an X-linked dominant allele bc there are no blue male offspring in cross 2.

Which of the following best supports the hypothesis that the difference in leaf color is genetically controlled

The existence of yellow-leaved seedlings as well as green-leaved ones on day 14 in dish B

Which of the following best describes the likely mode of inheritance for the eye-color gene?

The eye-color gene is likely autosomal bc males and females have similar phenotypic ratios.

In the cross diagram of, the expected an observed results are shown. Which of the following best explains the observed results of the cross?

The genes for body color and wing shape are located close to each other on the same chromosome

How would the extra chromosome affect male offspring produced by the gamete?

The male offspring would have full-color vision, bc of the presence of an extra X chromosome

Which of the following statements best completes the chi-squared goodness of fit test?

The null hypothesis can't be rejected bc the chi-squared value is less than the critical value at 0.05 freedom

Cinnabar eyes and vestigial wings question

The two genes are linked on an autosome

Which of the following best explains the cause of the phenotypic variation observed in the butterflies?

There was differential gene expression of wing color and boy size in response to the colors of light the caterpillars were exposed to
