Small body (nb), short spines (Is) and amoral are three recessive traits in stick the genes of which are linked on the same chromosome An heterozygous fish for all these used in a testeross and the following progeny was observed: Number 150 N 120 N 65 Progeny genotype nb ls* a/ nb ls a nb ls at / nb lsa -nb ls' a / nb ls a nb lst a / nb ls a nb ls a/ nb lsa nb ls nb is a nb sa/ nb ls a nb 19a/ nb ls a Progeny phenotype nb'ls a nb ls at nb* 1st at nb lst a Inb ls at nb ls a nb ls* a* nb ls a 200- 68 70 Total 62 578 a. Are the three genes in coupling or in repulsion? Clearly define if in coupling or repulsion for each gene in pairwise combination (e. g., is nb in coupling or repulsion with respect to Is? And with respect to a?, etc. for each gene). nb and is are in coupling nb and is are in repulsion with a?

Chapter 11.1 & 11.2 notes section 11.1 1. every living thing has a set of ? inherited from its parents. 2. after becoming a ? , mendel spent several years studying ? and mathematics at the university of vienna. 3. during sexual reproduction, male and female reproductive cells join, a process known as ? . 4. pea flowers are normally ? , which means that sperm cells in pollen fertilize the egg cells in the ? flowers. 5. when mendel crossed plants with ? characters for the same trait, the resulting offspring had only one of the characters. 6. a ? is a specific characteristic, such as seed color or plant height, that varies from one individual to another. 7. filius and filia are the latin words for ? and ? . 8. the offspring of crosses between parents with different traits are called ? . 9.to mendel's surprise, all of the offspring had the character of only ? of the parents. 10. mendel's first conclusion was that biological inheritance is determined by ? that are ? from one generation to the next. 11. scientist calls the chemical factors that determine traits ? . 12. mendel's second conclusion is the ? . 13. the principle of dominance states that some alleles are ? and others are ? . 14. when mendel allowed the f1 plants to reproduce by self-pollination the traits controlled by ? alleles reappeared in about ? of the f2 plants in each cross.

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. an incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. purple offspring result. then, two of the purple offspring are crossed. according to the punnett square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete dominance? 1 in 4 2 in 4 3 in 4 4 in 4

Why does the earth spin slowly, not faster? is it possible to prove it scientifically? can you prove it with math?
