1. most are located on the Y chromosome
In mammals, the Y chromosome contains the SRY gene, which is responsible for sex determination in mammals. SRY gene is responsible for the development of a fetus into a male.

select the true statements regarding the roles of sex
chromosomes in human development.
Select the true statements regarding the roles of sex chromosomes in human development. The X chromosome does not contain functional genes. An individual missing the SRY region of the Y chromosome will be phenotypically female. XXX females develop normally except for some slight physical abnormalities. XO females are viable, whereas YO males are inviable. Female cells typically contain two active X chromosomes which are both actively transcribed.

Genies are and on chromosomes that carry information for protein production and that are sponsible for the inheritance of specific traits Genes exist in alternative forms called alleics. or a trail is inherited from each parent Like traits originating from genes on autosomes (non-se chromosomes), sex-linked to omosomes), sex-linked traits are passed from parents to offspring...

Read each question carefully. Write your response in the space provided for each part of each question. Answers must be written out in paragraph form. Outlines, bulleted lists, or diagrams alone are not acceptable and will not be scored. The sex of an organism is typically determined genetically, but environmental factors can also play a role. Scientists examined the roles of genes and environmental temperature in the sex determination of a lizard species. Individuals with aZW pair of chromosomes are always...

Which of these statements is incorrect? Syntenic genes are located on the same chromosome. Independent assortment results in recombinant chromosomes. You can reliably predict the relative genetic distance from genes’ physical distance on a chromosome. Linked genes are always syntenic. What is the relative genetic distance between two linked genes if the recombination frequency is 0.49? 0.49 cM 4.9 cM 49 cM 490 cM What statement best explains the distortion in Mendelian ratios observed by Bateson & Punnett in 1905?...
