According to Carl Sagan in "The Dragons of Eden": Large organisms such as human beings average about one mutation per ten gametes [a gamete is a sex cell, either sperm or egg] -- that is, there is a 10 percent chance that any given sperm or egg cell produced will have a new and ...

To find the types of gametes produced, we can use the principle of independent assortment. Each allele can combine with each of the other alleles. The possible combinations of alleles in the gametes can be determined as follows: - From Yy, the possible alleles are Y and y. - From Rr, ...
How many different gamete genotypes can be produced from the Ee Ff AA genotype? Show Genes A, B, C, D, and E are not linked. How many different genotypes would you expect to find among the gametes from a plant with the genotype AaBbCCDdEe? What is the number ...
When using a Punnett square to predict offspring ratios, we assume that a. each gamete contains one allele of each gene. b. the gametes have all possible combinations of alleles. c. male and female gametes combine at random. d. All of these are correct. Using the Punnett square to demons...
Science instructors need questions for use in exams, homework assignments, class discussions, reviews, and other instructional activities. Textbooks never have enough questions, so instructors must find them from other sources or generate their own questions. In order to supply biology instructors with ...
Fly toward those mountains, head to the left a little when you see the ocean, and make a nest in the first nice-looking tree you can find. Whales traveling in the Pacific Ocean near the North American west coast use this method -- their landmark is hard to miss, because it's the ...
Driving endonuclease genes (DEGs) spread through a population by a non-Mendelian mechanism. In a heterozygote, the protein encoded by a DEG causes a double-strand break in the homologous chromosome opposite to where its gene is inserted and when the brea
In live-bearing animal lineages, the evolution of the placenta is predicted to create an arena for genomic conflict during pregnancy, drive patterns of male sexual selection, and increase the rate of speciation. Here we test these predictions of the vivi
3. Quantitative trait loci and epigenetics related to parasites on research platforms 3.1. Comparison between research platforms We adopted the null hypothesis (H0) that the research platforms used and/or the number of keyword combinations do not interfere in the number of articles returned.
