not having a human on board to deal with unexpected problems
Explanation:
I just had the same one
Answer:
only females
Explanation:
In humans, sex chromosomes in males and females are different. The sex chromosomes found in humans are X and Y chromosomes. X-linked trait is a trait which is inherited on the X- chromosome. According to the question, the trait is passed on a X-linked dominant condition, which means the condition is inherited on the abnormal dominant X-chromosome that will express itself even when in an heterozygous state with a normal X-chromosome.
Hence, a father affected by the condition will have a genotype; XY while a mother that does not have the condition will have a genotype: xx (two normal x chromosomes). Since the Father can only pass his X chromosome to his daughters and never his sons, all his daughters will inherit the condition (see the punnet square in attached image).
N.B: None of the sons will inherit the condition since the mother will pass normal X-chromosomes (x) to her sons.
Answer:
Since it will help the individual live longer, there is a greater chance that it will reproduce than those with lesser favorable traits. Thus the next generation will resemble the parents with the favorable triat more.

Answer:
4 RW pink hair color
Explanation:
Let the allele for red hair color = R
Let the allele for white hair color = W
Let the allele for blue hair color = b
Since R and W exhibit co dominance it means none of both traits have the tendency or capability to masked the other .
As such individual with RW genotype = PInk hair color
Allele b is recessive and only individuals with the genotype bb exhibit the blue allele
Now; if a cross occurs between a red-haired Mendelian and a white-haired Mendelian
i.e
RR × WW
we have
R R
W RW RW
W RW RW
So we have the following offspring :
4 RW = 4 pink
So theoretically , the possible phenotypes results to 4 RW pink hair color
