Answer:
The correct answer is B. No jaws. The new species resembles an ostrachodermi.
Explanation:
Ostrachodermi is an extinct class of agnate fishes, considered as the most ancient vertebrate. They were little filtering organisms, with no mandible or jaws, and no paired fins. Their bodies were covered by squama, bony plates, and shields. They used to move in the bottoms when they were feeding on detritus.
Answer:
35%
Explanation:
If two genes are 30 map units apart, 30% of the produced gametes will be recombinant.
A mating between an individual homozygous dominant for both traits (AB/AB) and one homozygous recessive for both traits (ab/ab) is conducted.
The F1 will be heterozygous for both genes: AB/ab.
The F1 progeny is then test-crossed to a homozygous recessive individual:
<h3>AB/ab X ab/ab</h3>
<u>The possible offspring will be:</u>
- Parental (70%): AB/ab and ab/ab
- Recombinant (30%): Ab/ab and aB/ab
Since 30% of all the gametes produced by the F1 individual will be recombinant, 70% will be parental. As there are two types of parental gametes, each of them will have a frequency of 35%.
<u>The offspring that will have a dominant phenotype for both traits has the genotype AB/ab with a proportion of 35%.</u>
