In hamsters, there is a dominant allele (S) for smooth fur and a recessive allele (s) for spiky fur. A unique characteristic of

these alleles is that the heterozygote (Ss) has its own phenotype - rough fur. In this way, we can determind the number of heterozygotes in the population. In a population of 1000 hamsters, 390 have smooth fur (SS), 470 have rough fur (Ss) and 140 have spiky fur (ss).
What are the allele frequencies in this population?
Frequency of S =
Frequency of s =

Answer:

<em>What are the allele frequencies in this population?</em>

  • Frequency of S = 0.625  
  • Frequency of s = 0.375

<em>In the next generation of 1000 hamsters, what are the expected genotype frequencies?</em>

  • Frequency (SS) = 0.39          
  • Frequency (Ss) = 0.47          
  • Frequency (ss) = 0.14  

<em>What are the expected number of each genotype in the next 1000 hamsters?</em>

  • Individuals SS =  390
  • Individuals Ss =  469
  • Individuals ss =  140

<em>Have the allele frequencies changed?</em> No, they are the same

<em>Is the population in Hardy-Weinberg equilibrium?</em> Yes, it is.  

<em>The expected genotype frequency of Ss (2pq) in the next generation is expected to be: </em>0.469 (option a)

<em>The expected number of smooth fur hamsters (SS) in the next generation of 1000 hamsters is</em>: 390

Which statement is true regarding cystic fibrosis? It is autosomal-dominant. It affects endocrine glands. It is common in Africa
stepan [7]

Answer:

The correct answer is - It is the most common genetic disease in the United States.

Explanation:

Cystic fibrosis is the genetic disease that affects the several body system and organ such as lungs and digestive system. This hereditary disease is autosomal recessive.

It is not common in ethnic populations such as African Americans and Asian Americans while in white population of US it is a very common genetic disease as it occurs in one individual in every 2500 to 3500 white infants.

Thus, the correct answer is - It is the most common genetic disease in the United States.

The predatory bacterium Bdellovibrio bacteriophorus drills into a prey bacterium and, once inside, digests it. In an attack upon
vagabundo [1.1K]

The correct sequence of structures penetrated by B. bacteriophorus on its way to the prey's cytoplasm is capsule, lipopolysaccharide membrane, peptidoglycan, phospholipid membrane.

What is  cytoplasm?

The gelatinous liquid that makes up a cell's interior is called cytoplasm. It is made up of different organic compounds, salts, and water. The cytoplasm is kept apart from some internal organelles, like the nucleus and mitochondria, by membranes.

Therefore,

The correct sequence of structures penetrated by B. bacteriophorus on its way to the prey's cytoplasm is capsule, lipopolysaccharide membrane, peptidoglycan, phospholipid membrane.

Monocotyledons are to grains and cereals as dicotyledons are to _________ ?
marusya05 [52]
Monocotyledons:<span>Embryos have a single seed leaf, referred to as a cotyledon - hence the name mono (one) cotyledonLeaves have parallel venation and are generally strap-like in appearanceFlowers have petals and floral parts in multiples of threeIn the stem, vascular bundles are scattered and absence of vascular cambium explains absence of secondary growthA pollen grain with one openingRoot system is generally fibrous, shallow and adventitiousStomata can be found on both epidermal layers of monocot leaves. This condition is called amphistomaticExamples of monocot plants are: (grasses) most ornamental turf lawns, (bamboo's) ornamental and wild bamboo's inlcuding sugar cane, (grain plants) rye, rice, wheat, maize (bulbous plants) such as lilies, agapanthus, clivia, orchid varieties, most palm tree varieties</span>


<span>It should be noted that Monocotyledonous plants make up one huge slice of the worlds cereal/ edible crops, the staple diet of literally Billions of people and animals! </span>

 Dicotyledons:<span>Embryos have two seed leaves, referred to as cotyledons - hence the name di (two) cotyledon - although dicots now known as eudicots, most people still use the term "dicot"Leaves have branched venationFlowers have petals and floral parts in multiples of four or fiveIn the stem, the vascular tissue is arranged circularly and presence of vascular cambium explains ability to effect secondary growthA pollen grain with three openingsRoot system is generally branched, but taproot basedStomata can only be found in the lower epidermis. So, we describe it as hypostomatic conditionExamples of dicot plants include: (veg) tomatos, peppers, cabbage, beans, peas, (flowers) sunflowers, roses, daisies, violets, petunia, pansy (fruit) apples, pears, cherries, avocardo</span>
