eimsori [14]

Answer:

Interrupted mating experiments can determine gene order on the Hfr bacterial chromosome.

Explanation:

Interrupted mating is a technique used in experiments involving microbiology. This experiment was created by geneticists François Jacob and Elie Wollman, in the late 1950s. This technique allows the mapping of the genes of the bacteria involved in the place where the conjugation was interrupted, within monitored and controlled time intervals. In this way, the technique allows showing the transfer mechanisms and the gene transfer itself.

In relation to the question above, we can say that the interrupted mating experiments can determine the order of the genes on the bacterial chromosome Hfr.

EXPERIMENT 1: PUNNETT SQUARE CROSSES Part 1: Post-Lab Questions 1. Set up and complete Punnett squares for these crosses (rememb

zvonat [6]

2. Answer: a. Resulting phenotypes: 100% Yellow.

b. No, there are not blue kernels.

c. All kernels are yellow because the yellow allele (Y) is

dominant over blue allele (y).

Explanation: Crosses a (YY x Yy) and b (YY x yy) result in yellow offspring with genotypes: 1) Dominant homozygote (YY) and 2) Heterozygous (Yy).

4. Answer: a. Genotypes: YY (25%) , Yy (50%) and yy (25%).

b. Phenotypes: Yellow (75%) and blue (25%).

c. There are more blue kernels in the F2 than in the F1.

Explanation: Crosses between F1 members (Yy x Yy) result in yellow and blue offspring with genotypes: 1) Dominant homozygote (YY, 25%) 2) Heterozygous (Yy, 50%) and 3) Recessive homozygote (yy, 25%).

5. Answer: a. Ys and YS

b. YS, yS, Ys, ys.

Explanation: The yellow and smooth individuals with genotype (YYSs) can produce two different gametes: Ys (Yellow and wrinkled) and YS (Yellow and smooth). The yellow and smooth individuals with genotype (YySs) can produce four different gametes: YS (yellow ans smooth), yS (Blue and smooth), Ys (Yellow and wrinkled) and ys (Blue and wrinkled).
