Answer #1

Option 1

​​​​​​The trait which skips generation is a recessive trait. In this case, unaffected parents can have affected progeny and vice versa. This trait is caused by two recessive mutation. Therefore first option is correct.

Second option is incorrect because this trait is caused by homozygous recessive mutation.

Third option is incorrect because the trait is having a recessive phenotype.

Last option is incorrect because heterozygous phenotype results in the dominant phenotype.

Please give a good rating.

In a Mendelian cross, a red flowering heterozygous male plant is crossed with a white flowering homozygous female plant. Most of the children of this cross (generation F1) produce red flower. 1) In this crossing by the progeny produced we can conclude that the recessive allele is: a-produce white flower b-produce red flower c-produce pink flower d-the recessive allele cannot be determined 2) phenotype of the female parent plant is: a-produce red flower b-homozygous dominant c-homozygous recessive d-produce white flower...

Which of the following correctly describes this cross? Choose all that apply. Now determine the genotypes of the possible gametes and set up a Punnett square for the cross between two double heterozygotes, as you did before in a previous question (no need to attach that Punnett square). From your Punnett square, determine how many individual kernels have the genotypes and phenotypes shown in the table below. Enter your answers as a number (e.g. 7) not a word (e.g. seven)...
