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.

A point mutation changes the DNA sequence CGA to CGT, but the same protein is still produced. Which point mutation occurred? A.

iren [92.7K]

The answer is C.silent.

Nonsense, missense, silent, and frameshift mutations are point mutations. The point mutations are the change in a single nucleotide base on the DNA molecule. In a missense mutation, the change in a single nucleotide base results in a codon coding for a different amino acid. In a nonsense mutation, the change in a single nucleotide results in a stop codon or in a nonsense codon. Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and totally different translation. In all these cases, the change could lead to different of nonfunctional protein translation.
Silent mutation, on the other, means that change in a nucleotide base will no affect amino acid. It will result in a different codon, but the one that code for the same amino acid, so the same protein will be produced.
