What Evidence of color blindness is recessive x linked trait?
His mate is color-blind
Is green eye color a recessive trait?
Green and blue eyes are caused by the same gene. So neither would be dominant over the other.
Which parental pair could produce female with color blindness?
X' = color blindnessX'X'-- X --X'Yis a cross that could lead to a color blind female as the mother is homozygous recessive and the father's X chromosome is the recessive color blind trait.
Is color blindness a dominant or a recessive trait?
Color blindness is a recessive sex linked trait.
A color-blind woman mates with a male with normal color vision Which of these results would indicate that color blindness is caused by an X-linked recessive allele?
All the sons would be color-blind and none of the daughters are color-blind.
What is the probability that a woman who is a carrier of the colorblind gene and a color blind man will have a first son who will be color blind?
The probability is 0 (but the daughter will be a carrier of the color blind gene). This is because the gene dictating whether someone is color blind or not is linked to the X chromosome (and not the Y). The color blind gene is a recessive gene whilst the normal color vision gene is a dominant gene. Hence if a girl (XX) has one normal vision gene (from one parent) and one color blind gene (from the other parent), her normal vision gene will be dominant to the recessive color blind gene and hence she will have normal vision (but she will be a carrier of the color blind gene). If both her parents contribute the recessive color blind gene to her, then she will be color blind. For a woman (XX) to be color blind, she needs to be have both genes to be recessive (ie where there is no dominant normal color vision gene to dominate). For a man (XY), as long as the X gene contributed by his mother is a color blind gene, he will be color blind because he has no other X chromosome where a dominant normal color gene could reside. Hence, to answer the question, a man with normal color vision (XY, with a dominant normal color vision X gene since the gene can't be the recessive color blind gene otherwise he will be colorblind) and a colorblind woman (XX, both recessive color blind genes), will each contribute an X each the child. The man will contribute his only X chromosome which carries the normal color vision X gene and the woman can only contribute a recessive color blind gene. The man's normal color vision X gene will be dominant, and hence the daughter will definitely have normal vision (despite being a carrier).
Do you get your eye color from your parent?
Yes you get your eye color from your parent. The parent that carries one dominant gene and one recessive gene for a specific eye color and the other parent carries two recessive genes for a different eye color, you will get the eye color of the parent who carries the dominant and recessive gene. In other words, the dominant gene trumps the recessive gene. In another scenario, if both parents carry two recessive genes for a specific eye color, then you will inherit the recessive gene of that color.
Is color blind a dominant trait?
BLhah
Is a female colorblinded trait dominant?
It is dominant. Most likely if the female had children then all her sons would be color blind. If she herself was also color blind then all her children would be color blind too.
What is the color of the baby eyes if the mother have the recessive gene for blue and the father has blue eyes?
I assume you mean the mother has a dominant allele for some other color. Father is homozygous recessive for blue. Dominant allele + recessive blue X recessive blue + recessive blue The baby has a 50% chance of blue eyes and a 50% chance of getting the dominant colored eyes.
What can be dominant or recessive?
Alleles can be dominant or recessive
What Evidence of color blindness is recessive x linked trait?
His mate is color-blind
Is green eye color a recessive trait?
Green and blue eyes are caused by the same gene. So neither would be dominant over the other.
What is colour blindness recessive?
Yes, Color Blindness is recessive, Not dominant. :)
How many recessive allelles does a male inherit to be color-blind?
1
What is dominant recessive?
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
Which parental pair could produce female with color blindness?
X' = color blindnessX'X'-- X --X'Yis a cross that could lead to a color blind female as the mother is homozygous recessive and the father's X chromosome is the recessive color blind trait.
