Mendel's work was ignored for about 35 years, until it was essentially replicated. Meanwhile, cell biologists worked out the details of meiosis and mitosis to try to understand inheritance.   True  False

Part 1: Make a three part process drawing (like a cartoon strip) to demonstrate Mendel's Principle of Segregation. Use two parents with homologous chromosomes marked with alleles "A" and "a". Circle and label these three action parts of the Principle of Segregation: a) parents are diploid, b) alleles separate to form haploid gametes (indicate when this happens), and c) gametes from each parent combine at random to form diploid offspring Part 2: Use the cross Aa x Aa and a Punnett square to demonstrate Mendel's Principle of Segregation. Circle and label these three action parts of the Principle of Segregation: a) parents are diploid, b) alleles separate to form haploid gametes and c) gametes from each parent combine at random to form diploid offspring. Part 3: Use homologous chromosomes marked with alleles "A" and "a" and a second pair of homologs marked with alleles "B" and "b". to demonstrate Mendel's Principle of Independent Assortment in cells in Meiosis. Indicate what phase this…

The image shows a pair of homologous chromosomes from a single parent before gamete production. M1 and M2 are maternal chromosomes, while P1 and P2 are paternal chromosomes. Two traits are shown: D represents seed color (D – green, d – yellow), while F represents flower color (F – purple, f – white). These two traits follow the patterns of basic Mendelian genetics. During crossing-over between the M2 F allele and the P1 f allele, a mutation occurred and the portion of P1 did not reattach to the chromosome. Which of the following explains what would happen to the proportion of white flowers in a population resulting from this mutation? A - There would be an increase in the proportion of white flowers because the f allele is distributed to more gametes. B - There would be a decrease in the proportion of white flowers because the f allele is not distributed to as many gametes. C - There would be an increase in the proportion of white flowers because the f allele would not be masked by the…

Below is a pedigree of a family with a history of X-linked recessive color blindness. We will use XB to represent the wild-type allele and Xxb to represent the mutant allele of the gene that leads to color blindness. The color vision status of the individuals with a question mark (?) is unknown. Part 1 Drag the correct genotype for each individual to the boxes under the pedigree symbols for the first two generations. O I. II. O1/4 O 1/2 O 3/4 xBxBxbxbxby xbxB XBXB or xbxB xBy O 0 Part 2 What is the probability that the female child in Generation III will be color-blind? Ⓒ1/4 1/2 O 3/4 000 O 0 0 Part 3 What is the probability that the male child in Generation III will be color blind? ? Autosomal dominant Autosomal recessive ? C Part 4 Are the first two generations of this pedigree consistent with the following modes of inheritance? ✓ No Yes
