Tides are caused by the suns and the moons gravity pulling water away from the planet. When the sun, moon and earth are at right

Answer:

When the sun, moon and earth are at right angles, this is called a neap tide.

When the sun, moon, and earth are parrallel to each other, this is called a spring tide.

Explanation:

There are two types of tides spring tide and neap tide.

A spring tide occurs when the sun and moon are parallel to each other. This usually happens during periods of full and new moon, which are the moments that the moon can form a straight line with the sun, causing the gravitational force to interfere with the tide.

The neap tide, on the other hand, happens when the sun, moon and earth are at right angles. This moment occurs between the waxing and waning moons, where the sun and moon are at right angles and the earth is used as a vertex of that angle. In this type of tide the gravity of the sun becomes more influential than that of the moon.

Suppose that to snow leopard’s, heterozygous for both traits meet. Suppose further that in the female, the two dominant alleles
Ber [7]

Complete question:

Snow leopards live in the high reaches of the Himalayas and have several adaptations to deal with living most of the time in snow. They have wide paws with hair between the toes to allow them to run on top of the snow crust. Assume that wide paws (W) and hair between the toes (T) are both dominant traits and are on the same chromosome. Suppose that two snow leopards, heterozygous for both traits, mate. Suppose further that in the female, the two dominant alleles are on the same chromosome of the homologous pair, while in the male, each chromosome of the pair has one dominant and one recessive allele.

1) What percentage of each of the following genotypes will be produced?

  • WWTT:
  • WWTt:            
  • WWtt:
  • WwTT:
  • WwTt:
  • Wwtt:  
  • wwTT:
  • wwTt:
  • wwtt

2) How many of the offspring (assume 4 cubs) will have narrow paws with hair between the toes?

Answer:        

1) Percentage of each of the following genotypes

  • WWTT: 0
  • WWTt: 1/4 = 25%        
  • WWtt: 0
  • WwTT: 1/4 = 25%
  • WwTt: 0
  • Wwtt:  1/4 = 25%
  • wwTT: 0
  • wwTt:1/4 = 25%
  • wwtt: 0

2)  Offspring with narrow pows: 1 of four individuals.

Explanation:

<u>Available data:</u>

  • wide paws (W) and hair between the toes (T) are both dominant traits
  • narrow paws (ww) and no hair (tt) are bothe recessive traits
  • Both traits are on the same chromosome.
  • Female: W and T on the same chromosome of the homologous pair, w and t on the other chromosome.
  • Male: W and t on the same chromosome of the homologous pair, w and T on the other chromosome.

Cross: Between two heterozygous individuals

Sex)        Female              Male

F1) Genotypes:

  • 1/4 WWTt
  • 1/4 Wwtt
  • 1/4 WwTT
  • 1/4 wwTt

      Phenotypes:

  • 2/4 = 1/2 = 50% wide paws with hair (W-T-)
  • 1/4 = 25% wide paws with no hair (W-tt)
  • 1/4 = 25% narrow paws with hair (wwT-)
