What percent of the offspring will receive the recessive phenotype when crossing two heterozygous individuals? assume normal dom
Irina-Kira [14]

The answer is 25%. The other 75% will have dominant phenotype. However, in the dominant phenotype, 25% have a homozygous dominant genotype, while the remaining 50% have a heterozygous genotype. Find attached a punnet square that will clearly illustrate this;

Answer:

The given situation is an example of the <u>Positive feedback loop</u><u>.</u>

Explanation:

Positive feedback is the phenomenon in which the effects of the small disturbances on a particular system can result in an increase in the perturbation magnitude. Positive feedback increases the input and causes instability in the system. Therefore, it refers to positive loop gain about closed loop of the cause and effect.

<u>Therefore, the given situation is an example of the </u><u>Positive feedback loop</u><u>. </u>

3.6 In mice, the allele C for colored fur is dominant over the allele c for white fur, and the allele V for normal behavior is d
KengaRu [80]

Answer:

a)  Parents Genotype should be (CC,Vv) and (cc,VV).

b) The genotypes of the parents are (Cc,Vv) and (Cc,Vv).

c) The genotypes of the parents are (Cc,Vv) and (cc,vv).

Explanation:

<h2>                                      (<u>a)</u> </h2>

Mating has occured between a normal colored mice whose genotype is C_,V_  and normal white  mice with genotype cc,V_. The offsprings are as follows :

1) normal mice produced 29 colored

2) 10 colored, waltzing progeny.

Thus all offspring are normal. The genotype of the first parent should therefore be CC. Waltzing trait is produced. The V gene should therefore be heterozygous in both traits.

Hence The parent genotypes should be<u> (CC,Vv) and (cc,CV).</u>

<h2>                                      (b)</h2>

In this case the approximate ratio in which the descendants are produced is 9:3:3:1. Hence genotypes of the parents are <u>(Cc,Vv) and (Cc,Vv). </u>

<h2>                                      (<u>c)</u>  </h2>

In this case the approximate ratio in which the offsprings are produced is 1:1:1. The genotypes of the parents are <u>(Cc,Vv) and (cc,vv). </u>
