Which describes a mature speed in terms of the number of chromosomes it contributes during reproduction?

Identify structure A. Identify structure B. Identify structure C. Identify structure D. 3209-03-07-20-02

Vika [28.1K]

Answer: Plant Cell

Explanation: Since I cant see in your question about what structure is about I have found that it might be the plant structure and I hope that this would help. I will also post you a picture of it.

A is Vacuole

B is Chloroplast

C is Cell membrane

D is Golgi bodies

E is Smooth and rough endoplasmic reticulum

F is Cell wall

This structure is a plant cell structure and it has a cell wall and plasma membrane.

Also, it has vacuoles in the center that are taking much space since they are huge.

Since it is a plant cell it has a chlorophyll and with it organelles and both of them are called chloroplasts.

Chlorophyll is giving the plant cell a green color. This kind of cell is a basic and the most important for the Plantae kingdom organisms.

When a male pig from a line of true-breeding (homozygous) black, solid-hooved pigs was crossed to a female from

natita [175]

Answer:

When a male pig from a line of true-breeding (homozygous) black, solid-hooved pigs was crossed to a female from a breed (homozygous) of red, cloven-hooved pigs, their several progeny all looked alike with regard to color and hooves. These progeny were all mated to members of the same breed as their red, cloven-hooved mother pig. The offspring from this final cross were: 11 black, cloven-hooved; 8 black, solid-hooved; 14 red, cloven-hooved; and 10 red, solid-hooved. For each of these two genes (coat color and hoof type) determine which allele is the dominant one. Explain your reasoning. What were the phenotypes of the progeny produced by the first mating in this problem.

In chickens, comb shape is determined by genes at two loci (R, r and P, p). A walnut comb is produced when at least one dominant

mariarad [96]

Answer:

in the obtained options, there is no dominant gene for the crossed pairs, therefore, no answer would be correct, however, when assigning a dominant character to the P gene, the correct answer would be:

E. Rr pp *rrPp

Explanation:

According to the information obtained we deduce:

Comb shape is produced by R and P

Comb of walnuts with an R or a P

Pink comb: 1 dominant P and R at the first locus and 2 recessive at the next locus

Pea comb: 2 recessive at the start and one dominant in the next position

1 single comb: 2 recessive at both loci

Rr pp × rr Pp will produce from the interbreeding: 2 walnuts, 1 single and 1 pea offspring.

We deduce that for the pink comb the genotype is: Rrpp

and for the pea comb it is rrPp

Rr pp × rr Pp generates crosslinks containing RrPp, rrPp, rrpp as children in a 2: 1: 1 ratio.
