In Amaryllis large flower inflorescence (F) is dominant over small (f) and strapped leaves (S) is dominant over non-strapped (s). An F1 derived from pure lines is test crossed and below are the progeny phenotypes: 81 were strapped and have large flowers 79 were non-strapped and have large flowers 68 were strapped and have small flowers 72 were non-strapped and have small flowers Use X2 analysis to determine if these genes exhibit Mendelian inheritance.

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?

Variety of living organisms; includes genetic, species, and ecological types.

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