Most reptiles and all birds are oviparous, meaning that their young develop in fertilized eggs laid outside the mother's body. In contrast, most mammals are viviparous, meaning that their young develop inside the mother's body.
<span>
The main difference between these two groups is that oviparous animals do not undergo any embryonic development inside the mother whereas viviparous do.</span>

16. Why should the recessive phenotype be used first to determine the q squared value instead of the dominant phenotype to deter
podryga [215]

The recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

<h3>What is a recessive phenotype?</h3>

A recessive phenotype is a phenotype which expresses the recessive trait of a gene.

The recessive phenotype is always h0m0zygous for that triat to be expressed.

In the Hardy-Weinberg equilibrium equation, the allele and phenotype frequencies are given as follows:

  • p^2 + 2pq + q^2 = 1

where;

  • p^2 is the h0m0zygous dominant phenotype frequency
  • 2pq is the heterozygous phenotype frequency
  • q^2 is the h0m0zygous recessive phenotype frequency

Therefore, the recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.
