15. The red color of tomato fruits and the round shape are determined by dominant autosomal genes located on the same chromosome at a distance of 18%
crossing-over. A plant with red and round fruits crossed with a plant having yellow
and oval fruits. It is known that the first plant is derived from the crossing of a plant
variety with yellow and round fruits with a plant variety with red and oval fruits.
What is the probability of offspring with yellow oval fruits?

Which of the following statements describes how the characteristics of different species of mammals reflect the evolutionary relationships among those species? shared anatomy among mammals, such as hair and mammary glands, suggests that a common ancestral species had these features. similarities in the dna and protein structures of mammal species suggest that these species evolved from a common ancestor. although all modern species of mammals share some features, the differences between them mean they cannot share a common ancestor.

Guinea pig coat color is determined by a single gene. the allele for black coat color is dominant to brown. in a cross between twoblack-haired guinea pigs, 20 offspring are born. if both parents were heterozygous, probability would predict that approximately howmany of the 20 offspring would have brown hair?

The activity of the modern sample is 1.10 bq . how long does that measurement take?
