A new human species was found on a distant planet, whose genetic inheritance and process of reproduction is identical to that of
Vedmedyk [2.9K]

Answer:

  1. E/e ; T/t  ⇒ Square eyes and long tail (Option D)
  2. 3/16 will have round eyes and long tails (Option C)
  3. 1/4 of the progeny will be heterozygous for both traits (Option A)

Explanation:

<u>Available data</u>:

  • Two diallelic unlinked genes
  • Gene E controls eye shape: Dominant allele E expresses square eyes, and recessive allele e expresses round eyes.
  • Gene T controls the tail size. Dominant allele T expresses long trail, and recessive allele t expresses short tail.

<u>Genotypes                                          Phenotypes</u>

EETT, EeTT, EETt, EeTt                     Square eyes and Long tail

eeTT, eeTt                                          Round eyes and Long tail

EEtt, Eett                                             Square eyes and Short tail

eett                                                      Rounf eyes and short tail.

<em>1. An individual of this new species is heterozygous for gene E and heterozygous for gene T. What is their genotype and phenotype?</em>

The heterozygous individual is E/e ; T/t, expressing square eyes and a long tail.

<em>2. Two individuals, who are both heterozygous for eye shape and tail size, mate. Which of the following is a correct statement about the phenotype ratios expected for their offspring?</em>

Cross: between two heterozygous individuals

Parentals) EeTt    x     EeTt

Gametes) ET, Et, eT, et

                ET, Et, eT, et

Punnett square)  .   ET        Et        eT       et

                  ET     EETT    EETt    EeTT    EeTt

                  Et      EETt     EEtt     EeTt      Eett

                  eT    EeTT    EeTt    eeTT     eeTt

                   et     EeTt      Eett     eeTt      eett

F1) Genotype:

  • 1/16 EETT
  • 2/16 EETt
  • 1/16 EEtt
  • 2/16 EeTT
  • 4/16 EeTt ⇒ 1/4 EeTt
  • 2/16 Eett
  • 1/16 eeTT
  • 2/16 eeTt
  • 1/16 eett

      Phenotype

  • 9/16 E-T-, Square eyes and Long tails
  • 3/16 E-tt, Square eyes and short tails
  • 3/16 eeT-, Round eyes and Long tails
  • 1/16 eett, round eyes and short tail

Phenotypic ratio 9:3:3:1

<em>3. From the mating described in question ABOVE, what proportion of ALL of the offspring in will be heterozygous for both traits?</em>

4/16 = 1/4 = 25% of the progeny are expected to be heterozygous for both traits, EeTt.

The amount of biomass that is produced in an area during a given time would be referred to as?
sweet [91]

Answer:

Explanation:

The amount of biomass that is produced in an area during a given time is referred to as primary production/productivity.

<h3>What is biomass?</h3>
  • Renewable organic material obtained from plant and animal sources if referred to as biomass.
  • Primary productivity is the production of organic compounds through the process of photosynthesis, with the help of solar energy.
  • Primary productivity is measured as biomass produced per unit area over a give time period
  • It is usually expressed either in weight or energy.
  • There are two ways to express primary productivity:

a) Gross Primary Productivity(GPP): Takes into account the total energy produced in the ecosystem.

b) Net primary Productivity(NPP): Takes into account, solely the energy used by the producer for respiration.

Define excretion and list the ecretory product of mammals and indicate where each product is formed​
Troyanec [42]

Answer:

Excretion is a process by which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life.
