What is the similarities between sex linked traits and sex influenced traits?
the difference between learned behavior and inherited traits is leared behavior non of your gens will run in your family. And inherited traits most of or (all of) your gene will run in your family in other words your inherited traits will be pass down from genration to genration
Explaine the sex of an infant is genetically determined at conception.?
Male sex is tied directly to the Y sex chromosome. The Y chromosome codes for the proteins and enzymes that cause the changes that makes one phenotypically male. Any fetus without a Y chromosome will be genotypically and phenotypically female, only by lack of those proteins and enzymes mentioned before. Given that one sex chromosome comes from the ovum and one comes from the sperm, which fuse at conception, the genotypic and phenotypic sex of the fetus is determined at the time of conceptual fusion of the spermatozoa and ovum.
What is is a segment of DNA that contains the information necessary to express the inherited traits of an organism.?
It Contains the sex cell or a protein I am doing this on study island you guys should know this!
What is the difference between an autosomal mutation and a sex-linked mutation?
Autosomal traits are inherited via genes that do NOT determine an individual's sex. Sex-linked traits, however, are inherited via genes that DO determine and individual's sex (X and Y chromosomes). (The use of Punnett squares is the best way to help visualize this difference.) Autosomal traits are passed on from parents to offspring independent of gender, whereas, because sex-linked traits are carried on the X chromosome and NOT the Y chromosome, males (XY (hemizygous)) have a 50% chance of being either recessesive or dominant for the trait . With sex-linked traits, females however have more possible outcomes in terms of dominant/recessive traits because of their two X chromosomes (XX). This means that both Xs may be dominant (homozygous dominant), both Xs may be recessive (homozygous recessesive), or one X may be dominant while the other is recessive (heterozygous- the dominant trait would be physically represendted). Some examples of autosomal traits are ability/inabilitiy to roll toungue, freckles/no freckles, widows peak/continuous hairline, etc. Two examples of sex-linked traits are Colorblindness and Hemophilia.
What is allele inherited on sex chromosomes?
Sex-linked gene
How are sex-linked traits inherited?
Sex-linked traits are inherited from the organism's parents.
How is the sex of an individual determined?
Scientists do not determine the sex of a fetus. Science does, but scientists do not.
How are hemophilia and red-green color blindness inherited?
Both are sex-linked traits, inherited through the X chromosome.
When can sex of fetus be determined?
I belive my doctor said sometimes as soon as 16 weeks
How many weeks pregnant is the gender of the fetus formed?
gender is determined at the moment of conception, however it isn't until around the 16th to the 17th week of pregnancy that the sex of the fetus can be determined by ultasound.
What are the principles of genetics?
# Sex cell of a plant or animal may contain one factor (allele) for different traits but not both factors needed to express the traits. # Characteristics are inherited independently from other characteristics. # Each inherited characteristic is determined by two heredity factors/genes, one from each parent which determine whether a gene will be dominant or recessive.
Why is the genotype of the father unimportant when investigating sex linked traits inherited by the male offspring?
Fathers pass the Y sex chromosome to their sons, NOT the X sex chromosome.
Why is genotype of the father unimportant when investigating sex-linked traits inherited by male offspring?
Fathers pass the Y sex chromosome to their sons, NOT the X sex chromosome.
How are sex linked traits inherited?
Sex-linked traits are inherited from the organism's parents.
What are the different ways that sex is determined in the fetus?
Well, you pray to god for a girl or a boy, and then you hope that god will grant your wish.
What are the three principles of Heredity?
The 3 main points of how traits are inherited are: 1)Traits are controlled by alleles on chromosomes. 2) An allele's effect is dominant or recessive. 3)When a pair of chromosomes separates during meiosis, the different alleles for a trait move into separate sex cells.

Is your fetus a female during the first trimester of pregnancy?
Your fetus' sex is determined at fertilization. However, the external genitalia don't start developing until the 11th week of gestation, but will still not be visible on ultrasound.
