Gargoyles are tetraploid. A single gene determines whether they have wings or not. This gene has a completely dominant winged allele (W) and a recessive wingless allele(w). Now cross two winged gargoyles with genotypes WWWw  X  WWWw. so what will be the possible distribution of the progeny ?

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

These circles represent cells. The first cell is going through meiosis, and the 2 meiotic divisions are shown. Draw 4 chromosomes in the first cell. Two of these will be longer, and are homologs to each other; and two will be shorter and these will also be homologous to each other. Each pair of chromosomes will have exchanged parts due to “crossing over.” (Show crossover by shading or coloring, starting in the very first circle.) Follow the chromosomes through the 2 divisions.

Could the trait presented in the pedigree shown be caused by an X-linked recessive allele? Why or why not? 11 ||| IV ■ 5 6 Yes, with individual 2 of generation I being heterozygous. No, the offspring of 7 and 8 contradict an X-linked recessive inheritance. No, the offspring of 3 and 4 of generation II contradict an X-linked recessive inheritance. No, the offspring of 1 and 2 of generation I contradict an X-linked recessive inheritance.

In this pedigree, which parents-child pair allows you to reject the hypothesis of X- linked dominant as an inheritance pattern? If there are more than one pair, just pick one possibility. Be careful that the person is really a child. Specify generation and number. Use the notation format "I1-|11" II 12 3 III 1 3. 6. 7 8 9.

The presence of horns on satyrs is produced by a sex-influenced autosomal gene that is dominant in males and recessive in females. A horned female is crossed with a hornless male. The F1 are then intercrossed to produce the F2. What proportion of the F2 generation will be horned? O % of the males and none of the females O % of males and % of females O All of the males and none of the females O % of the males and % of females O ½ of the males and none of the females

In the world of Weeping angels, those with pointy wings are (A_), while those with round wings are (aa). In the efforts to explore this extraordinary species, you wish to determine the genotype of a pointy winged angel. Luckily, you have trapped a round winged angel that you can cross your pointy winged angel with. If the pointy winged angel is homozygous what phenotypic ratio do you expect from their offspring? (Pointy wing: round wing) Group of answer choices a. 1:0 b. 2:1 c. 1:1 d. 3:1
