4 genes existed in the tangerine to contribute the segment number. Because after crossing the F1 generation having maximum 8 alleles which are dominant controls the 12 segment character whil le if none of the dominant allele is present then it control the 4 segment of tangerine.

1. A series of unlinked genes contribute in an equal manner to determine the number of flowers in an inflorescence for a plant species. Two pure breeding lines, one with 4 flowers and a second with 12 flowers per inflorescence. After the cross is performed the F1 plants have 8 flowers per inflorescence. The F1 plants as crossed with each other and the resulting F2 produces plants with as few as 4 flowers per inflorescence and as many as 12....

6) You cross two pure-breeding strains of peas, one with white flowers and the other with purple flowers. All progeny (Fi) from this cross have purple flowers. You cross two F1 individuals, harvest the F2 seeds, and plant a row of twelve (12) seeds in your Aunt Mabel's front yard to improve the landscaping.

Question 29 0/2 pts Two unlinked, epistatic genes regulate production of flower pigments in diploid sweet peas, as shown in the metabolic pathway below. Each gene codes for the production of an enzyme, and each gene has two possible alleles-dominant and recessive. Plants with at least one dominant R allele will produce the blue pigment. Plants with at least one dominant R allele and at least one...

Question 2 0.5 points Save As Suppose that in plants, smooth seeds (5) is dominant to wrinkled seeds (s), and tall plants () is dominant to short plants (t). An F1 plant from a mating between homozygous plants that were tall/smooth and short/wrinkled was crossed to the short/wrinkled parent. What proportion of the progeny is homozygous for short and wrinkled alleles? 1/2 1/4 1/8 1/16 O 00 A Which genotypic ratio indicates a recessive lethal allele when two heterozygotes are...

1. In humans, red-green color-blindness is a sex-linked (carried on the X chromosome) recessive trait. If a woman who is not color blind but whose father was color-blind marries a man who is not color-blind, what is the probability that their first child will be a daughter who is color- blind? a) 0 b) 25% c) 50%- d) 100%- e) cannot tell from the information given 2.

please answer two question below
thankyou
e) 9; 9 3. In another plant species, the presence and type of hairs on the plant are controlled by epistatic interaction between two independently assorting genes. Gene C determines whether the plant has hairs (dominant) or not (recessive); Rene D determines whether the hairs are straight (dominant) or curly (recessive). In a cross between a straight-haired plant and a curly- haired plant, 1/4 of the offspring have no hairs. 3/8 have straight hairs,...

I have the answers to the two question below. Can you help explain why the answers please. Thanks Considering factors that account for the differences in Gene/ Allelic expression that lead to modidied Mendelian ratios. Tell whether the statements are True and Flase. a. Modified Mendelian ratios do arise as a result of patial expression of alleles in the heterozygote. True b. Typical Mendelian ratios are the result of the simultaneous expression of two alleles in the heterozygote. False c....

You cross two crows, one with yellow legs, and the other with green legs. All of the F1 offspring have purple legs. Leg pigment is produced by the pathway in Fig.3, where the dominant alleles (Y and G) produce functional versions of enzymes Y and G, and the recessive alleles (y and g) produce nonfunctional enzymes.
