The overall goal of IPM is to reduce the environmental and health risks of pesticides within social and economic constraints.
Fix: The scope of IPM implementation will continue to change greatly in the future. What began as limited approaches to promote integration of control methods for key pests and provide guidelines for decisions regarding pesticide applications is evolving to an ecologically-based systems approach.
The nurse can instruct the husband to encourage her wife to breathe deeply and slowly to alleviate pain and discomfort during contractions. Patterned breathing can help the wife to cope with pain during labor, it will also increase oxygen supply of the mother and the baby too.
Answer:
A) One-half of their daughters will have normal color vision and brown eyes; 1/2 of their daughters will have normal color vision and blue eyes.
Explanation:
<u>The genotypes and phenotypes are</u>:
- BB or Bb= brown eyes
- bb= blue eyes
- XᴰXᴰ, XᴰXᵈ (women) or XᴰY (men)= normal vision
- XᵈXᵈ (women) or XᵈY (men) = color blind
A woman has blue eyes (bb) and normal color vision (she has an Xᴰ chromosome) but her father was color-blind, so the other X chromosome she has carries the recessive d allele. She has the genotype bb XᴰXᵈ.
The man has normal color vision (he is XᴰY) and has brown eyes, but his mother had blue eyes so he must have inherited a b allele from her and is therefore heterozygous Bb. His genotype is BbXᴰY.
The blue/brown eyes gene is autosomal and independent from the sex-linked color blindness gene.
The woman can produce the gametes b Xᴰ and b Xᵈ.
The man can produce the gametes B Xᴰ, b Xᴰ, B Y and bY.

<u>The female daughters can have the following genotypes and phenotypes:</u>
- Bb XᴰXᴰ brown eyes, normal color vision
- Bb XᴰXᵈ brown eyes, normal color vision
- bb Xᴰ Xᴰ blue eyes, normal color vision
- bb Xᴰ Xᵈ blue eyes, normal color vision
