Answer:

A . II and IV only.

Explanation:

  • Process is defined as the series of steps that are followed to achieve certain goal.
  • In the flow chart I, III and V show raw material, the parts and Mp3 player. respectively.
  • None of these involves steps or method.
  • Step II shows Production. It involves methods and steps that convert the raw material in to product. Thus, it is a process.
  • Step IV show assembly. Assembling also involves series of steps and method that combine the part to make the Mp3 player. Thus it is also a process.

When colorblind women married a male with normal vision, all their daughters have normal vision and all their sons are colorblin
worty [1.4K]

Answer:

X-linked recessive

Explanation:

The trait is a sex-linked trait because the daughters are not colorblind, but the sons are. We know this its recessive because the daughters have inherited the mother's X chromosome that has the colourblindness trait, but are not colorblind because the father's X does not have the colourblindness trait. The sons are colourblind because they inherited the X from their mother with the colourblindnese trait and a Y from their father. The colourblindness trait or normal vision trait is not carried on the Y, so the mother's X chromosome's trait is expressed.

Sorry if it's confusing i tried my best to explain it

Parallel venation is a kind of venation in which the veins runs parallel to the to the length of the leaves from its base of the leaf to the apex of the leaf or the tip of the leaf.

It is a characteristics of many monocot plants.

Few example of plants having parallel venation are grasses, bamboo, rice, corns, banana, musa, canna, etc.

If a blue eyed mother with a normal vision has a brown eyed color blind son and a blue eyed colored blind daughter what are the
Rina8888 [55]

Answer: mother: XX^aa, father: X^YAa, son: X^YAa, daughter: X^X^aa.

Explanation:

Color blindness is a genetic disorder that affects the ability to distinguish colors. It is hereditary and is transmitted by an X-linked recessive allele. If a male inherits an X chromosome with the altered allele he will be color blind. In contrast, females, who have two X chromosomes, will only be colorblind if both of their X chromosomes have the altered allele. This is because <u>males have one X chromosome and one Y chromosome, while females have two X chromosomes</u>.  

If the woman has normal vision, that means she cannot have both chromosomes affected. She can only have one affected chromosome (be a carrier) or none at all. Also, if she has blue eyes, which is a recessive trait, then both alleles are recessive. But the eye color is not on the X chromosome. For example, her eye color genotype can only be aa, because if she had at least one dominant allele she would have brown eye color. As for the other trait, she can be XX^, with X^ being an affected (carrier) allele or XX, i.e. both normal. So in summary, her genotype can be XXaa or XX^aa  

If she has a brown-eyed male child who is also colour blind, he has inherited the allele for colour blindness from his mother, since the father does not pass on an X chromosome to the male children, only the Y. With this we can now rule out the mother's XXaa genotype since she had to have passed on her affected X^ chromosome. Then the genotype of the mother is XX^aa. And since her mother can only pass on one allele to (recessive) because she does not have allele A, the dominant that determines her brown eye color can only come from the father. So the genotype of this son is X^YAa. The female daughter has color blindness and blue eyes. So she had to inherit the affected X^ chromosome from the mother (which we already know she has) and an affected X^ chromosome from the father, because the daughter needs to inherit both affected X^ chromosomes to develop the disease. And if she also has blue eyes, she had to have inherited a recessive allele from the mother and another from the father. So with this information we can say that the father's genotype can only be X^YAa. Because the father must have both A and A alleles of the same eye color, because he passed the dominant one to the son and the recessive one to the daughter. At last, the genotype of the daughter is X^X^aa.
