Biology
1 answer:
Leokris [45]2 years ago
4 0

During Pangea, Madagascar and India were one landmass. The species of frogs were homogenous across the landmass. However, after continental drift that began approximately 88 years ago, allopatric speciation occurred to form different species on the two continents.

The dusky salamanders on the two continents that could once reproduce viable offspring 88 years ago, cannot reproduce viably today because they have diverged into two different species now.

An individual who is heterozygous for a gene has:
Phantasy [73]

Answer:

A.

Explanation:

When we say that an individual is <u>heterozygous</u>, it means that the two alleles at the locus we are studying are different from one another. That is, each one of the parents contributed a different allele.

On the other hand, If the alleles at that locus were the same we would say the individual is <u>homozygous</u>. In other words, the two parents contributed each the same type of allele.
