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.
What protein does the eye color gene encode?
The eye color gene encodes for a protein called OCA2 (P gene), which helps determine the amount of melanin produced in the iris. Melanin is responsible for the color of the eyes, with more melanin resulting in darker eye color.
Morphological expression of a gene?
The morphological expression of a gene refers to the physical traits or characteristics that are determined by that gene. This includes features such as eye color, hair color, or leaf shape that can be observed and measured in an organism. These traits are the result of gene expression and interaction with the environment during development.
What Evidence of color blindness is recessive x linked trait?
Inheritance pattern: Color blindness is caused by a recessive X-linked trait, meaning the gene responsible for color vision is located on the X chromosome. Transmission: Since males have only one X chromosome, a single copy of the recessive gene will result in color blindness. Females need to inherit two copies of the gene to be color blind. Prevalence: Color blindness occurs more frequently in males because they have a higher chance of inheriting the gene from their carrier mothers.
A pink snapdragon has two genes that determine its color there is a white gene W and a red gene R the parent snapdragons only pass along one gene for color to an offspring What color will offspring be?
If the parent snapdragons pass along a white gene (W) to the offspring, then the offspring will be white. If the parent snapdragons pass along a red gene (R) to the offspring, then the offspring will be red.
What is gene located on the x chromosome?
The gene located on the X chromosome that codes for a protein involved in producing eye pigment is called the OPN1LW gene. Mutations in this gene can lead to color vision deficiencies, such as red-green color blindness.
What is the location of the eye color of a fruit fly meaning which chromosome?
The locus for eye color is on the X chromosome.
Where is the gene for fruit flies eye color?
The gene for fruit fly eye color is located on the X chromosome. It codes for a protein called "eye color," which determines the pigmentation in the eyes of the fruit fly. Mutations in this gene can lead to different eye colors in fruit flies.
What is gene g responsible for in these fruit flies?
Gene g in fruit flies is responsible for determining the color of their body. It codes for a specific protein that influences the pigmentation of the flies, resulting in variations in body color among individuals. Mutations in gene g can lead to changes in body color, which can be used to study gene expression and inheritance patterns.
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.
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).
What is the rufus gene?
It is a coat color gene in animals that is responsible for the deep orange color as in tigers.
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.
What protein does the eye color gene encode?
The eye color gene encodes for a protein called OCA2, which plays a role in determining the color of the eyes.
How can a mutation in a gene lead lead to a new trait in an organism?
The mutated gene codes for a protein that cause a new trait
What is a single gene that affects more than one trait?
The gene called MC1R, which codes for the melanocortin 1 receptor protein, can influence multiple traits such as skin and hair color, as well as sensitivity to pain. Variations in this gene can lead to differences in pigmentation and response to certain stimuli.
What protein does the eye color gene encode?
The eye color gene encodes for a protein called OCA2 (P gene), which helps determine the amount of melanin produced in the iris. Melanin is responsible for the color of the eyes, with more melanin resulting in darker eye color.
