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:

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

Explanation:

Available data:

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.

Genotypes Phenotypes

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.

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

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

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?

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

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

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

Why is it beneficial to use textiles made from synthetic fibers

mestny [16]

Synthetic fabrics are textiles made from man-made fibers rather than natural fibers. Chemically produced fabrics are made by joining monomers into polymers, through a process called polymerization. A synthetic fabric, when magnified, looks like plastic spun together.

Natural fabrics, such as cotton, silk, and wool, are made from animals or plant based fibers. While synthetic are man made and produced entirely from chemicals to create fabrics. such as polyester, rayon, acrylic, and more. The benefits of using textiles made from synthetic fibers is that it saves the animals and plants that the fibers are based off of.

Hope this helped :)
