What crosses will reasult in all dominant phentotype offspring

Biology
1 answer:
Mars2501 [29]4 years ago
6 0

The dominance or recessivity associated with a particular allele is the result of masking, by which a dominant phenotype hides a recessive phenotype. By this logic, in heterozygous offspring only the dominant phenotype will be apparent.

hope this helps!

Ipatiy [6.2K]

Answer;

Bit clock

-Bit clock is the name given to the clock signal that occurs evenly spaced time durations during which data signals are sent in synchronous transmissions.

Explanation;

The term "bit clock" is used to describe a one cycle per sample "square wave" signal used for internal synchronization within digital audio equipment.

-In synchronous  transmission data signals are sent along with a clock signal which occurs at evenly spaced time duration referred to as the bit time. On the other hand, in asynchronous  Data signals are transmitted without an associated clock signal. The time spacing between data characters or blocks may be of arbitrary duration, meaning the spacing is not standardized. Therefore, frames require start and stop indicator flags.

Nataliya [291]

Answer:

sun/ visible light

moon/ invisible light

Explanation:

The Sun is the dominant source for visible-light waves our eyes receive. The outer-most layer of the Sun's atmosphere, the corona, can be seen in visible light. But it is so faint it cannot not be seen except during a total solar eclipse because the bright photosphere overwhelms it.The moon shines because its surface reflects light from the sun. And despite the fact that it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it.

when two true breeding pea plants that show contrasting traits are crossed 1) mention the pod shape in F1 generation 2)work out
agasfer [191]

Answer:

1.) Inflated pod shapes (Cc) in the F1 generation

2) See attached image for the work out of the cross from P generation to F2 generation.

3). CC- 1/4, Cc- 1/2, cc- 1/4

Explanation:

This question is related to the pod shape trait encoded by a single gene in pea plants. The alleles for inflated pod shape (C) is dominant over the allele for constricted pod shape (c). This means that allele "C" will be expressed over allele "c" in a heterozygous state.

The two truebreeding parent plants will have genotypes: CC (inflated pod shape) and cc (constricted pod shape). When these two plants are crossed, an all heterozygous plant with genotype: Cc will be formed in the F1 generation. Since, C is dominant over c, the F1 Cc plants will have an inflated pod shape phenotype.

The F1 Cc plants are self-crossed to produce the F2 generation offsprings i.e. Cc × Cc. The gametes C and c will be produced by each F1 parent, which will be used to draw a punnet square (see attached image). From the cross, offsprings with genotypes: CC, Cc and cc are produced in the F2 generation.

CC (phenotypically inflated pod shape)- 1/4

Cc (phenotypically inflated pod shape)- 1/2 or 2/4

cc (phenotypically constricted pod shape)- 1/4
