- The nucleus of udder cell which was used to develop Dolly was taken from_______.a) Six year old Finn Dorset white sheep b) Seven year old white sheep. c) Six year old goat d) Five year old cowThe image above shows that, with respect to the WRN gene, the individual with Werner syndrome (WRN) is: Choice 1 of 2: Heterozygous Choice 2 of 2: HomozygousGive typing answer with explanation and conclusion to all parts The chromosomes drawn below are found in a human skin cell. The lines represent the chromosomes themselves. The letters indicate the location of a particular version of a gene. a) T/F An individual’s offspring are more likely to inherit a D1 and R together than a D1 and T9 together. b) T/F About 50% of the egg cells from this individual will have both T9 and BA5. c) T/F Because r is recessive, the frequency at which the r version of the gene occurs in a population is lower than the frequency at which the R version occurs in the population. d) T/F If the protein produced by the BA gene is involved in the formation of ovaries, then the BA gene is likely located on a sex chromosome. e) T/F Because the genes shown here are found in skin cells, these genes code for proteins required for skin cell function.
