Dominant alleles are expressed while recessive are only expressed if both parents have recessive genes. For example, parents with the alleles DD and Dd will have offspring with children DD, DD, Dd, Dd.

<span>The offspring received one allele from each parent. The alleles were separated during gamete formation before they were passed to the offspring. The offspring received the G allele for green pod color from one parent, and they received the g allele for yellow pod color from the other parent. Green pod color is dominant, resulting in the offspring having the green pod color.</span>

Answer:

Genotype ratio = 1 X^hX : 1 XX : 1 X^hY : 1 XY

Phenotype ratio = 2 normal daughters : 1 affected son : 1 normal son

Explanation:

Given that the father of the woman has hemophilia, the father must have transferred the allele for hemophilia (let us assume "h") to her. This makes the woman carrier for the disease (genotype = X^hX). The genotype of the normal man would be "XY".

A cross between carrier woman and normal man would obtain 2 normal daughters, 1 affected son and 1 normal son.

Genotype ratio = 1 X^hX : 1 XX : 1 X^hY : 1 XY

Phenotype ratio = 2 normal daughters : 1 affected son : 1 normal son

Answer:

The correct answer is a. Potassium hydroxide (KOH) preparations

Explanation:

Potassium hydroxide preparation is a simple test which is carried to identify the fungal infection invaded in skin, nails, vagina, etc. KOH degrade the keratin or mucous present on sample and clears the background which makes fungal cell more visible under the microscope.

In this method sample from infected area is collected and placed in the center of the slide then a drop of KOH is added on it. After this coverslip is put on the sample and the slide is heated gently to increase the reaction rate of KOH. Then the slide containing fungus is examined under the slide. KOH test is used for both yeast and molds. So the right answer is a.

Alborosie

Oxygen production of plants different at different times of the day due to presence of sunlight.

In cellular respiration, oxygen is taken in and carbondioxide is releases in the environment whereas in photosynthesis, carbondioxide is taken inside and oxygen is releases in the atmosphere so in this way matter is conserved during the processes of photosynthesis and cellular respiration.

Oxygen production of plants different at different times of the day because oxygen only produced when there is photosynthesis process which only occurs in the presence of sunlight. If plant was placed in a completely dark environment then there is no oxygen is produced and no photosynthesis occur.
