Widow peak (H) is dominant to a straight hairline (h), and long eyelashes (E) are dominant to short (e). d. A homozygous widow peak man who is heterozygous for eyelashes mates with a straight hairline homozygous for long eyelashes woman. Genotype: A a Bb Complete the punnett square on the next page with this information. i. Use FOIL to determine the possible gametes and then create a dihybrid cross for this mating. F 01 Foil Method: A a B b Gametes: AB Ab aB ab Example of how to write ratios Ratios of possible phenotypes of offspring FOIL (mom) FOIL (dad) 2 tall: 2 short 2 HH: 2 hh

In pea plants, spherical seeds (S) are dominant to dented seeds (s). In a genetic cross of twoplants that are heterozygous for the seed shape trait,i. Explain the diagram ii. What fraction of the offspring should have spherical seeds? iii. Use punnett square to show your answer. iv. Interpret the results of a Punnett square

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…

A female with the genotype RRMM is crossed with a male with the genotype rrmm. Which of the following shows a dihybrid cross of the resulting F1 generation? Select one: O a. RRMM x Rrmm O b. RRMM x rrmm O C. RR x rr O d. Rr x rr Ое. RrMm x RrMm O f. Rr x Rr

please thoroughly explain why the asnwer is b

In the example below, crossing you left thumb over your right thumb is dominant T to crossing your right over left recessive t. Identify the genotype of the individual shown below: OShutterstock / robynleig O A. homozygous dominant (TT) O B. heterozygous dominant (Tt) or homozygous dominant (TT) OC. homozygous recessive (tt) O D. Cannot be determined from information provided

Gregor Mendel developed an understanding of heredity through his experiments with pea plants. The diagram below shows a cell with 2 pairs of homologous chromosomes and genotype of AaBb. a. Identify all the possible allele combinations that could be formed if this cell undergoes meiosis. b. Identify one of Mendel's laws that is illustrated when you write out these allele combinations. EXPLAIN this law.

Imagine you are a medical professional, and your patient is pregnant with a child whose karyotype has been determined. The unborn child's karyogram is shown below in the picture.   Create the symbol for this result, and then speculate on the outcome of this pregnancy, based on what you know about the viability of human trisomies.
