Suggest two factors which may have caused ammonitites to become extinct

Biology
1 answer:
WARRIOR [948]3 years ago
4 0

Answer:

A 7.5 mile wide asteroid slammed into the Earth and killed off more than three-quarters of the all species on the planet. There were many changes caused due to the impact. Ocean acidification likely dissolved the shells of their microscopic young ones. Fossil records also shows that the impact wiped plankton species which was their main food source.It starved the ammonites.

Hope it helps :)

Two genes, A and B, are located 30 map units apart. A mating between an individual homozygous dominant for both traits and one h
Westkost [7]

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>
