Wedow et al. (2018) found that genes which predispose an individual towards gay sex:     improve reproductive success in female siblings.     are related to a higher number of heterosexual partners in the same individual     are not a viable reproductive strategy     are on the X gene

Q1

Which reproductive strategy is more likely to result in offspring with traits that are well-suited to specific and unchanging environmental conditions? Group of answer choices Asexual Sexual Both sexual and asexual Neither sexual and asexual

3 Use the Punnett Square below to identify the phenotypes of the offspring. FEMALE SEX CELLS R RR Rr MALE SEX CELLS Rr rr Red petals are dominant over white petals. A RR, Rr, rr 75 % Red and 25 % white 25% Red, 50 % red and white, 25 % white 25 % Red, 50 % pink, 25 % white

How do mitosis and meiosis differ? Q 15 of 15 Meiosis occurs as sex cells reproduce and engage in crossing over, while mitosis occurs as DNA replicates itself. Mitosis occurs in females, and meiosis occurs in males in sexual reproduction. Mitosis is used to create the DNA in sex cells, and meiosis replicates cells within the body. Meiosis is involved in sex cell reproduction, which duplicates the 46 chromosomes, and mitosis is not.

CRCR (red flowers); CRCW (pink flowers); CWCW (white flowers); F (full leaves) > f (slender leaves); H (heat tolerant) > h (vulnerable to heat) G*G? (green leaves); GʻG? (green and yellow leaves); G?G² (yellow leaves) CRCR Ff Hh G1G1 x CRCW Ff hh GʻG? Box 1: Which trait displays incomplete dominance? Box 2: What is the PHENOTYPE of the second parent in the cross? Box 3: What is the probability of having an offspring which is completely HETEROZYGOUS? Show your work by listing the fractions and how you would determine the answer (add, subtract, divide, multiply, etc).

ZOOM 4) Color-blindness is caused by an X-linked recessive allele. A color-blind woman marries a man with normal color vision. What would be their children's phenotypes (in percent)? What percent of their offspring will be females with normal color vision, but who are carriers for the condition?

8. Identify the following. Gene found on Y chromosome but not X chromosomes Protein coded for by SRY gene Function of testis determining factor (TDF) Organ that secretes testosterone and Mullerian inhibiting factor (MIF) Hormone that promotes development of external genitalia along male line Protein that transforms Wolffian ducts into male reproductive tract organs Organ that develops in the absence of TDF SRY gene sex-determining region Y protein initiating male sex determination Testosterone

Explain in detail how does Swyer syndrome occur? (a person who is typically raised as female and has female external genitalia but also has a Y chromosome).  It has been noticed in the 2016 Olympics, as it was hotly debated.
