At one gene locus in humans there are 2 alleles: one for curly hair and another for straight hair. Neither allele is dominant, a
Dovator [93]

Answer:

25%

Explanation:

<u>Genotypes and phenotypes:</u>

  • SS = straight hair
  • CC= curly hair
  • SC = wavy hair
  • AA or A0= type A blood
  • BB or B0= type B blood
  • AB = type AB blood
  • 00 = type 0 blood

A man with straight hair and A blood has the genotype SS AA or SS A0.

A woman with wavy hair and B blood has the genotype SC BB or SC B0.

Their first child has straight hair and O blood: SS 00

Because the child has type 0 blood, both parents must have a 0 allele, so their genotypes are SS A0 and SC B0.

<u>If their second child is a boy with straight hair, what is the probability that he has A blood?</u>

The hair and blood type genes are independent, so the hair phenotype of the child is irrelevant to determine the probability of him having A blood.

The parental cross for blood type is A0 x B0.

If you do a Punnett Square, you'll get the following offspring:

25% AB, 25% B0, 25% A0 and 25% 00.

The answer is the child has a probability of 25% of having A blood.

Two Longleaf Pine forests, Forest A and Forest B, existed several miles from each other in Georgia. Forest A was very close to a
Ganezh [65]

The forest A which is near to the village will be saved by the local volunteers and hence suffers less damage as compared to forest B which was far away. Both the forest will go under secondary succession.

<h3>What is Ecological Succession?</h3>

Ecological succession is the process of changes in the species structure of an ecological community over time. The time scale for a succession to take place can be decades or more or less.

Succession begins with a relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable as a climax community.

The reason of succession is the cause of ecosystem change. It is the impact of established organisms upon their environments.

Succession is of two types: Primary Succession and Secondary Succession. When succession takes place on a bare rock then it is called primary succession as no species ever existed on that rock. However, when a forest catches fire the succession is secondary as species once existed on that place which were destroyed.

The time for secondary succession is less than the primary succession. The forest A which was near to the village will be saved by the local volunteers and hence it suffers less damage as compared to forest B which was far away.
