Answer:

The correct answer is option A.  

Explanation:

In amphibians, reptiles and other animals, the circulation is directed in 2 circulation systems.

galben [10]

Answer:

The results will be 50% heterozygous black dogs and 50% yellow dogs.

Explanation:

A punnet square can be described as a diagrams which predicts the outcomes of a cross being made.

A dominant trait can be described as the trait that dominates and masks the effect of the recessive trait. A recessive trait can be described as a trait that gets suppressed by the dominant trait.

When the two alleles of a gene are similar for a trait, they are said to be homozygous. When the two alleles of a gene are different, they are termed as heterozygous.

A cross between the heterozygous black fur dog with a yellow fur dog will show that there are 50% chances that the offsprings born will be heterozygous black as one of the parents or there is a 50% chance that they will be yellow as the recessive parent dog.
