PLS HELP!!
In a normal distribution, the number of organisms exhibiting a phenotype variant near the lowest value is(1 point)
-greater than the number exhibiting a variant near the highest value.
-greater than the number exhibiting a variant near the middle value.
-less than the number exhibiting a variant near the middle value.
-less than the number exhibiting a variant near the highest value.


Kamar is looking for his birth mother. Kamar knows that his blood type is AB and his father’s blood type is heterozygous A. What can Kamar assume about his mother’s blood type?(1 point)
-Kamar’s mother must be either AB or B because blood types AB is considered codominant.
-Kamar’s mother must be AB because blood type AB is inherited from one parent.
-Kamar’s mother must be O because the recessive allele allows for Kamar to get type A from his father.
-Kamar’s mother must be either A or O because blood type AB is considered incomplete dominant.

The different variants of a trait available to a gene are called(1 point)
-alleles.
-genotypes.
-polygenic traits.
-phenotypes.


A wolf populations’ undercoat thickness follows a normal distribution. Suppose climate change causes the winters to grow colder. Over many generations, the distribution of undercoat thickness in this population will likely(1 point)
-shift toward a thinner coat.
-shift toward a thicker coat.
-remain the same.
-no longer be normal.

HELPPPP PLEASE....
:)

Answer 1

1 is a: less than...middle value

2 is c: ab or b

3 is d: grade 10-12

4 is a: alleles

5 is a: ..... thicker coat

Explanation: just took this, these are the correct answers for MY quick check. could very well be different for yours. hope this helps though :)

Answer 2

1. The number of organisms exhibiting a phenotype variant near the lowest value is ; ( C ) Less than the number exhibiting a variant near the middle value.
2. Kamara can assume that ; ( A ) Kamara mother must be either AB or B because blood types AB is considered codominant.
3. The sample that is most likely to produce a normal distribution is ; ( A ) Grade 10-12,  Height Range 55 - 60 60 - 65 65 - 70 70 - 75 , Frequency 4 9 8 4.
4. Various variants of a trait available to a gene are called ( A ) ; Alleles .
5. The undercoat thickness in this population will likely ( B ); shift toward a thicker coat.

The wolves undercoat will grow towards been thicker in order to protect the wolves from extreme cold conditions posed by the winter and  this phenomena is called adaptation.

Blood types of offspring's are determined by the blood groups of both parents therefore if Kamara has a blood type AB his mother will mostly likely have either AB or B blood type.

Alleles are the different variants of a gene in living organisms but they are located at the same position on the chromosome.

Hence we can conclude that answers to the questions are as listed above.
