A human male (XY), on the other hand, has only one X chromosome, and so needs only one copy of the recessive allele to have the disease. Complete the Punnett square below of a cross between a carrier mother (a female who carries one copy of the recessive allele and so appears normal herself) and a non-hemophiliac father. 1. Drag the pink labels to the pink targets to indicate the sex dictated by the genotype in each box. (Pink labels may be used more than once.) 2. Drag the blue labels to the blue targets to indicate whether the genotype in each box confers hemophilia, normal, or carrier status. (Blue labels may be used more than once.) Reset Help x"x (carrier) mother xHY (normal) father Sperm…What are chromosomal disorders? Also gives a suitable example.A company that offers PGD terms an embryo “normal and healthy” if it has 46 chromosomes. Why is this statement misleading? , Two famous male actors had twins using a surrogate mother who carried two embryos that hadbeen fertilized in vitro, one with one man’s sperm and the other with the other man’s sperm. In terms of genetics, how closely are the babies, a boy and a girl, related to each other if they have different fathers?
- a. The 2 daughter cells produced from meiosis I are IDENTICAL/UNIQUE (choose one) compared to each other. Explain how you determined the cells were genetically identical or unique. b. The daughter cells are HAPLOID / DIPLOID (choose one) because homologous pairs ARE/ARE NOT (choose one) present in the same cell. The chromosomes in each daughter cell are DUPLICATED/ UNDUPLICATED (choose one). essibility: Investigate D Focus 87% 58°FExplain how genetics of inherited traits correlate to meiosis, mitosis, cell division, cell cycle, and other chromosomal physical properties? Be thorough in your explanation and provide examples for your reasoning.Why is karyotyping significant in understanding chromosomal abnormalities? Short essay only thanks please the main answer
- A 43-year-old (gravida 2, para 2) pregnant woman requests chorionic villus sampling (CVS) and a karyotype of her fetus because of concerns about Down syndrome. Chorionic villus cells reveal the following karyotype: 2 3 7 8 10 11 12 13 14 15 16 17 18 %3D 19 20 21 22 X X Y With this karyotype from CVS, discussion of the results with a genetic counselor would include which one of the following? a. Normal child b. Male with mild to moderate learning problems and infertility c. Female with mild to moderate learning problems and delayed puberty d. Generally normal male, however some degree of short stature and precocious puberty e. Generally normal female, however some degree of short stature and infertility1)Discusses why Meiosis I is referred to as reduction division and why Meiosis II is essentially like Mitosis. 2)Discusses where problems are likely to occur in Meiosis and what these problems could lead to.A. How many gamete classes would be formed from the following genotype: Tt Rr Ss Gg Yy? B. Deduce a simple formula for predicting the classes of gametes formed for heterozygous, diploid organisms, that can take into account number of genes being considered. Tt; TtRr; AaTtRr.
- a. What type of cell division mitosis, meiosis I or meiosis II is shown in this figure? b. What is the diploid number of this organism? c. Provide labels for (i) and (ii)A young couple is planning to have children. Knowing that there have been a substantial number of stillbirths, miscarriages, and fertility problems on the husband’s side of the family, they see a genetic counselor. A chromosome analysis reveals that, whereas the woman has a normal karyotype, the man possesses only 45 chromosomes and is a carrier of a Robertsonian translocation between chromosomes 22 and 13. Q. What types of zygotes will develop when each of gametes produced by the man fuses with a normal gamete produced by the woman?Writing a summary: Your younger sister comes barging into your room crying something about, “meiosis? mitosis? chromosomes? chromatids? genes? alleles? What does it all mean?” Being the great older sibling that you are, you agree to make a study guide for her that explains all the terms, how they are related, and why they are important. Your study guide includes a written summary and your hand drawn diagrams to help put all the terms into context.
