Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.

Can i please get help with the answer and please show me the work with an explaintion so I can understand
This question deals with Mendelian Genetics. Read each part carefully before you answer it. In the following questions, assume green pea pods are dominant over yellow pea pods. a) If a pea plant that is Heterozygous for pod color is crossed with a pea plant with yellow pods, what do you expect to see in the offspring (the f1 generation)? Specifically, what genotypes, what phenotypes, and in what ratios? (Use G for the green pod gene and g for the yellow pod gene.) (It is usually helpful to write out all the possible genotypes and give the phenotype for each genotype before answering the specific question.)

This question will test your Mendelian genetics knowledge! On a piece of paper, construct TWO Punnett squares (set up both of your Punnett squares like the example square provided below). In this classic Mendelian genetics cross, you will start with a female cat from a PURE BREEDING brown furred population. You mate this female with a male cat selected from a PURE BREEDING yellow furred population. BROWN fur is the dominant allele. In your first Punnett square, show the P generation cross, with the F1 generation results. Be sure to label this as your P generation cross! Use the correct genotype symbols, as used in standard dominant / recessive allele systems, to show all genotypes. In your second Punnett square, do a monohybrid cross of the F1 generation, to show the expected F2 generation results. Be sure to use the correct genotype symbols. Next to BOTH of your Punnett Squares, write out the expected genotype and phenotype ratios for the offspring generations. Use the TERMS used to…
