11. Genes may also be carried on the X chromosome, but never on the Y chromosome. These traits are known as X-linked traits. 12. The chromosomal theory of heridity states that genes are located on chromosomes. 13. Genes located on the same chromosomes are said to be linked. 14. A trait is made up of two alleles, one from your mom and one from your dad. 15. A description of a trait that an organism is expressing is called its genotype. 16. An organism that has two alleles that are the same for a trait is said to be homozygous. 17. When an organism has two different alleles for the same trait it is said to be heterozygous. 18. Dormant X chromosome in females are called barr body and can be used in gender verification.

A phenotypic trait is considered sex-linked when a trait occurs only in males the genes for the phenotype occur on X or Y chromosomes the phenotype is expressed only after sexual intercourse the phenotype occurs only in females the phenotype is polygenic for both sexes An individual that has two different alleles for the same trait is said to be polygenic. recessive. homozygotic. heterozygotic. pleiotropic.

1.Which of the following is TRUE? a) Genetics is about the genotype. b)Inheritance is controlled by factors and each offspring receives three factors from each parent. c)Allele pairs never segregate from one another. d)The principle of segregation states that genes for different traits assort independently of one another in the formation of gametes. e)Independent assortment of two traits shows a F2 generation that has a 9:3:3:1 phenotypic ratio. 2.A cross between a black rabbit (BB) and a white rabbit (bb)...

"The orange locus in cats is located on the X chromosome. In females, XoXo results in orange cats and X+X+ results in black cats When a female is heterozygous XoX+, they express both colors in patches due to a phenomenon called X-inactivation in which one X in every cell is inactivated. These females are called calico or tortoiseshell, depending on the presence of white spots. Male cats are either orange (XoY) or black (X+Y). A cross between a black female...

Probability and Genetics Lab In heredity, we are concerned with the occurrence, every time an egg is fertilized, of the probability that a particular gene or chromosome will be passed on through the egg, or through the sperm, to the offspring. As you know, genes and chromosomes are present in pairs in each individual, and segregate as they go into the gametes (egg and sperm). There are two possible genes (alleles) that the egg or sperm might obtain from each...

Simple Dominance with 2 genes A gene in cats causes them to be black (dominant) or brown (recessive). A second gene causes cats to be agouti (have stripes on their hairs) or non-agouti (solid colored hairs). If you did a dihybrid cross between two black haired agouti cats, what fraction of the offspring would be expected to have each phenotype? If a dihybrid black agouti cat mated with a brown cat that was heterozygous for the agouti gene, what fraction...
