What does the process of meiosis result in? - -A reduction in the chromosome number Why is crossing-over one of the most important events in meiosis? - -It produces new combinations of alleles on chromosomes. Which mode of inheritance describes a condition that exclusively affects males? - -Y-linked A man with disease X and a woman without disease X have five sons and five daughters. All of their daughters inherit the disease, while none of the sons do.Which mode of inheritance is described...

SimUText: Mendelian Pigs Latest 2023 Graded A+ Explain the general pathway of eukaryotic Membrane protein production in the nucleus of a diploid cell there are 2 alleles. They are both transcribed by RNA polymerase into premRNA. The premRNA is spliced and exits the nucleus where it is associated w/ a tRNA w/ the corresponding anticodon, causing the tRNA (linked to an amino acid) to bind to the ribosome. The mRNA does this by itself binding to the ribosome. The polypedide chain is synthesized. Ri...

Formation of a new species is called - ️️speciation As a mechanism of evolution, natural selection can be most closely equated with - ️️unequal reproductive success What is NOT an example of natural selection? - ️️On a tree, leaves that grow in the shade are larger than those that grow in the sun Which of the following pairs of anatomical structures are homologous? - ️️bat wing and human arm A gene pool is - ️️All of the alleles in a population The smallest bio...

how many species live in planet Earth? - ANSWER-unknown-roughly 3 to 5 million why is life so incredibly diverse, yet so strangely similar? - ANSWER-organisms can contain similar features. planes have wings, birds have wings-this feature is useful for different things (different for penguins, pelicans, bats, eagles) true or false: biodiversity on earth will likely decrease in the near future? - ANSWER- true or false: scientists believe in evolution even though they currently lack eviden...

Introduction: An organism’s traits, or characteristics, are controlled by genes. Genes are located on rod-like structures called chromosomes. Different versions of genes that code for the same trait are called alleles. In this Gizmo, there are 3 genes on each chromosome. For each gene there are eight possible alleles: W (white), R (red), G (green), B (blue), C (cyan), M (magenta), Y (yellow), and K (black). Question: Where does variation in a population come from? 1. Observe: Click on on...

what are two factors that contribute to phenotype? genotype and environment species individuals that are able to exchange genetic material gene pool all alleles present in individuals of that species populations interbreeding groups of organisms of the same species living in the same geographical area
