Biology
1 answer:
viktelen [127]3 years ago
5 0

Answer:

"The combination of sex chromosomes received from parents " .

Explanation:

Sex determination : The process by which sex of a child is determined .

Parental generation :

Mother         Father

XX                   XY (sex chromosomes )

X,X                   X,Y  (gametes )

First filial generation :

       X        Y

X    XX       XY

X     XX       XY

If XX is formed then it is girl and if XY is formed then it is boy .

Conclusion :

  • we concluded that there is 50-50 percent chance of boy or a girl .
  • Sex of a child is determined by father because father produce different gametes .

Occasionally, plates like the ones inoculated as part of this exercise are allowed to remain in the incubator for extended perio
34kurt

Answer and Explanation:

This happened because when the agar was desiccated, all the water was released, but the solutes used in the culture medium remained in the petri dish, that is, all the nutrients remained available to H. salinarium, which survived by consuming these nutrients. Although the growth of H. salinarium requires a higher level of NaCl than the level left in the petri dish, we can consider that some colonies of H. salinarium adapted to the low level of NaCl and managed to survive, passing this characteristic to new colonies.

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.
